1 00:00:00,320 --> 00:00:02,880 Speaker 1: Brought to you by the reinvented two thousand twelve camera. 2 00:00:03,240 --> 00:00:08,960 Speaker 1: It's ready. Are you get in touch with technology with 3 00:00:09,119 --> 00:00:17,960 Speaker 1: tech Stuff from how stuff works dot com. Greetings, loyal 4 00:00:18,079 --> 00:00:20,960 Speaker 1: tech stuff fans, and welcome to the podcast. My name 5 00:00:21,040 --> 00:00:23,480 Speaker 1: is Chris Polette. I'm an editor at how stuff works 6 00:00:23,480 --> 00:00:25,840 Speaker 1: dot com, and sitting next to me, as usual, is 7 00:00:25,960 --> 00:00:32,080 Speaker 1: senior writer Jonathan Strickland. Hoi hoi. Okay, it's interesting way 8 00:00:32,120 --> 00:00:35,120 Speaker 1: to start off our podcasts this afternoon. Right, Well, there's 9 00:00:35,120 --> 00:00:37,720 Speaker 1: another interesting way we could start off our podcast. Okay, 10 00:00:37,760 --> 00:00:45,840 Speaker 1: that would be with listener made Yeah. I feel ambushed. Yeah, 11 00:00:45,880 --> 00:00:48,680 Speaker 1: well you know you walked right into that one. So 12 00:00:49,200 --> 00:00:53,360 Speaker 1: here's a listener mail from Leanna, and Leanna says, I 13 00:00:53,400 --> 00:00:56,800 Speaker 1: was wondering what's USB two point oh all about? Will 14 00:00:56,840 --> 00:00:59,360 Speaker 1: all my peripherals for my laptop stop working if I 15 00:00:59,360 --> 00:01:02,160 Speaker 1: don't install a USB two point oh hub. It'd be 16 00:01:02,200 --> 00:01:05,840 Speaker 1: cool to hear a podcast on this, Thanks Leanna. Hopefully 17 00:01:05,880 --> 00:01:08,000 Speaker 1: we didn't get to this too late. USB two point 18 00:01:08,000 --> 00:01:11,640 Speaker 1: i has been around for a while, Yeah, quite some time. 19 00:01:11,920 --> 00:01:15,520 Speaker 1: Chances are you're actually using USB two point oh peripherals 20 00:01:15,600 --> 00:01:19,520 Speaker 1: right now. In fact, um, I would be very surprised 21 00:01:19,560 --> 00:01:22,200 Speaker 1: to hear that you were using USB one point one. Uh, 22 00:01:22,280 --> 00:01:24,000 Speaker 1: two point oh has been the standard for a while, 23 00:01:24,040 --> 00:01:27,320 Speaker 1: and three point oh. The three point oh um specifications 24 00:01:27,319 --> 00:01:30,559 Speaker 1: were released last year. We can expect to see USB 25 00:01:30,680 --> 00:01:34,440 Speaker 1: three point oh devices probably sometime in two thousand ten. 26 00:01:34,480 --> 00:01:38,520 Speaker 1: I would say, yeah, I've seen as early as this year, 27 00:01:38,720 --> 00:01:41,319 Speaker 1: but uh, it's gonna take him a while to get 28 00:01:41,360 --> 00:01:45,320 Speaker 1: it in rolled out into the in the individual Yeah, 29 00:01:45,319 --> 00:01:48,760 Speaker 1: things like things like digital cameras and and B three 30 00:01:48,760 --> 00:01:50,360 Speaker 1: players and all that kind of stuff. It'll it's gonna 31 00:01:50,400 --> 00:01:52,480 Speaker 1: take a little while. But you asked, what's the deal 32 00:01:52,520 --> 00:01:54,040 Speaker 1: about it? And do you need a hub and all 33 00:01:54,080 --> 00:01:56,800 Speaker 1: these kind of questions. We're gonna tackle that. So USB 34 00:01:57,040 --> 00:02:00,920 Speaker 1: it's really a method of transferring data back and forth 35 00:02:00,960 --> 00:02:07,360 Speaker 1: between different devices using a cable, a USB cable, yep um. USB. 36 00:02:08,040 --> 00:02:10,840 Speaker 1: Going back to uh the very beginning, USB is actually 37 00:02:10,840 --> 00:02:12,880 Speaker 1: sort of an old technology now. I mean one point 38 00:02:12,880 --> 00:02:16,960 Speaker 1: oh was launched in November, and the first really the 39 00:02:16,960 --> 00:02:18,960 Speaker 1: one that that really took off was one point one, 40 00:02:19,040 --> 00:02:23,840 Speaker 1: which came out in September, which, uh, ironically was the 41 00:02:23,880 --> 00:02:26,600 Speaker 1: same month that they launched the Bondai Blue iMac. The 42 00:02:26,720 --> 00:02:29,240 Speaker 1: very very first iMac, which was the first computer that 43 00:02:29,360 --> 00:02:33,959 Speaker 1: used only USB and no other technologies. Right, so you 44 00:02:34,040 --> 00:02:36,800 Speaker 1: might wonder, Okay, so what's the big deal with USB? USB? 45 00:02:36,919 --> 00:02:40,040 Speaker 1: First of all, it stands for Universal Serial Bus, and 46 00:02:40,240 --> 00:02:43,120 Speaker 1: a USB is just a way of connecting a device 47 00:02:43,160 --> 00:02:46,400 Speaker 1: to something like a computer. Um, actually it is a computer. 48 00:02:46,440 --> 00:02:49,679 Speaker 1: I mean computer acts as the host for for USB devices. 49 00:02:50,680 --> 00:02:53,040 Speaker 1: And the reason why USB is such a big deal 50 00:02:53,840 --> 00:02:57,400 Speaker 1: is before USB, you had lots of proprietary or very 51 00:02:57,520 --> 00:03:00,760 Speaker 1: specialized kinds of cables and plugs you had to use 52 00:03:00,840 --> 00:03:03,440 Speaker 1: for different kinds of devices if you wanted to hook 53 00:03:03,480 --> 00:03:07,639 Speaker 1: them up to your computer, like parallel cereal scuzzy. Yeah. Yeah. 54 00:03:07,680 --> 00:03:09,800 Speaker 1: You had all these different different things like if you 55 00:03:09,840 --> 00:03:11,880 Speaker 1: had a printer, then you were going to use a 56 00:03:12,480 --> 00:03:15,920 Speaker 1: parallel printer port, which were you know, these pretty wide 57 00:03:16,360 --> 00:03:21,560 Speaker 1: uh cables. Monitors had their own kind of connectors, modems 58 00:03:21,600 --> 00:03:24,240 Speaker 1: had their own kind of connectors um. And then you 59 00:03:24,280 --> 00:03:27,000 Speaker 1: had other devices like special joysticks or whatever where you 60 00:03:27,000 --> 00:03:30,360 Speaker 1: would have to buy a specific kind of card that 61 00:03:30,400 --> 00:03:33,680 Speaker 1: you would have to install inside your computer. UM and 62 00:03:34,200 --> 00:03:36,920 Speaker 1: the at one end of the card was essentially a 63 00:03:37,000 --> 00:03:40,680 Speaker 1: port and you would plug the device into that port 64 00:03:41,160 --> 00:03:44,440 Speaker 1: and pretty much. Usually those ports were only good for 65 00:03:44,680 --> 00:03:47,720 Speaker 1: very specific devices. You couldn't you know, you couldn't multitask 66 00:03:47,760 --> 00:03:50,480 Speaker 1: with one of these things. So it ended up where 67 00:03:50,480 --> 00:03:53,040 Speaker 1: you had all these different proprietary plugs and all these 68 00:03:53,080 --> 00:03:57,240 Speaker 1: different proprietary ports, and it wasn't easy to switch out gadgets. 69 00:03:57,320 --> 00:03:59,640 Speaker 1: Um if you decided that you wanted to upgrade, you 70 00:03:59,720 --> 00:04:02,680 Speaker 1: might have to buy a whole bunch of new new 71 00:04:02,720 --> 00:04:06,400 Speaker 1: hardware in order to upgrade. It just wasn't very convenient. Now, 72 00:04:06,560 --> 00:04:11,360 Speaker 1: the Universal Serial Bus is much more convenient because it's 73 00:04:11,360 --> 00:04:14,400 Speaker 1: a cable that if you create a device that uses this, 74 00:04:14,480 --> 00:04:16,720 Speaker 1: then you know you can plug it into the same 75 00:04:17,040 --> 00:04:20,560 Speaker 1: port as you would any other USB device. So you 76 00:04:20,600 --> 00:04:23,320 Speaker 1: could use let's say you've got a USB keyboard and 77 00:04:23,360 --> 00:04:26,640 Speaker 1: a USB mouse, and you also have a USB microphone, 78 00:04:26,720 --> 00:04:30,200 Speaker 1: and you have a USB uh MP three player. All 79 00:04:30,240 --> 00:04:32,560 Speaker 1: of those devices could plug into the exact same port 80 00:04:32,720 --> 00:04:35,560 Speaker 1: as your as any of the others to your computer, 81 00:04:35,680 --> 00:04:37,880 Speaker 1: unlike the old devices, which each had to have their 82 00:04:37,880 --> 00:04:43,080 Speaker 1: own that's right, and um USB has another serious, serious 83 00:04:43,080 --> 00:04:47,040 Speaker 1: advantage over those older technologies, which is it's hot swappable. 84 00:04:47,560 --> 00:04:49,520 Speaker 1: And what that means is if you have a printer 85 00:04:49,920 --> 00:04:51,960 Speaker 1: and uh, you want to plug it into your computer 86 00:04:52,000 --> 00:04:53,880 Speaker 1: and turn it on. You can plug it into your 87 00:04:53,880 --> 00:04:56,800 Speaker 1: computer and turn it on. UM, I'll give you an example. 88 00:04:57,040 --> 00:05:00,320 Speaker 1: I had most of you long time list. There's no 89 00:05:00,400 --> 00:05:03,760 Speaker 1: that I used to be a Commodore Amiga owner. Jonathan's 90 00:05:03,839 --> 00:05:05,920 Speaker 1: rolling his eyes. But what I used to use if 91 00:05:05,920 --> 00:05:08,160 Speaker 1: I wanted to plug something in was called Scuzzy, which 92 00:05:08,279 --> 00:05:12,919 Speaker 1: was an older technology, very fast. But UM, let me 93 00:05:12,920 --> 00:05:14,440 Speaker 1: explain what I'd have to do. To say, if I 94 00:05:14,480 --> 00:05:17,760 Speaker 1: wanted to to hook up a printer or um an 95 00:05:17,760 --> 00:05:21,479 Speaker 1: external DVD burner. Of course I didn't have those when 96 00:05:21,560 --> 00:05:23,640 Speaker 1: I used my Amiga, but if I wanted to do 97 00:05:23,680 --> 00:05:25,839 Speaker 1: that using the old interface, I'd have to turn my 98 00:05:25,880 --> 00:05:30,200 Speaker 1: computer off and turn the peripheral off, plug it in, 99 00:05:30,680 --> 00:05:32,880 Speaker 1: and make sure that there was a terminator plugged into 100 00:05:32,880 --> 00:05:36,280 Speaker 1: the external port on the Scuzzy device, and then turn 101 00:05:36,360 --> 00:05:39,120 Speaker 1: them on. Now, with USB, you can go ahead, plug 102 00:05:39,120 --> 00:05:42,560 Speaker 1: in your your you know, iPod, you can plug in whatever, 103 00:05:42,720 --> 00:05:45,880 Speaker 1: your keyboard, mouse. You don't have to worry about whether 104 00:05:46,000 --> 00:05:48,000 Speaker 1: or not it's gonna cause your computer to foul up, 105 00:05:48,080 --> 00:05:50,920 Speaker 1: because it would using some of those older technologies. So 106 00:05:50,960 --> 00:05:54,800 Speaker 1: this is very intuitive and and it's you know, you 107 00:05:54,800 --> 00:05:56,200 Speaker 1: don't have to mess with it. You don't have to 108 00:05:56,200 --> 00:05:58,520 Speaker 1: turn things off and worry about which one is in 109 00:05:58,600 --> 00:06:02,240 Speaker 1: what order, and those there are problems that USB really 110 00:06:02,279 --> 00:06:05,120 Speaker 1: made a difference in. It made it easier for manufacturers 111 00:06:05,120 --> 00:06:07,400 Speaker 1: to come up with a single standard that they could 112 00:06:07,480 --> 00:06:11,640 Speaker 1: use for PCs and MAX both. Right, Yeah, it was 113 00:06:11,680 --> 00:06:16,480 Speaker 1: actually a wonderful development. Um. When you when you plug 114 00:06:16,560 --> 00:06:19,880 Speaker 1: something into a USB board or when you turn on 115 00:06:19,880 --> 00:06:23,200 Speaker 1: a computer and things are already plugged into those ports, uh, 116 00:06:23,240 --> 00:06:27,560 Speaker 1: the computer goes through a process called enumeration, and in enumeration, 117 00:06:27,800 --> 00:06:30,839 Speaker 1: it it checks all the different ports and it assigns 118 00:06:30,920 --> 00:06:34,479 Speaker 1: an address to each device that is connected to the computer. 119 00:06:35,040 --> 00:06:36,880 Speaker 1: And the same thing happens when you plug something in 120 00:06:37,000 --> 00:06:40,080 Speaker 1: on the fly, and if the computer recognizes the device, 121 00:06:40,160 --> 00:06:42,920 Speaker 1: it works right away. If it doesn't recognize the device, 122 00:06:42,960 --> 00:06:45,720 Speaker 1: it might ask you for a driver, which you may 123 00:06:45,760 --> 00:06:48,080 Speaker 1: have either on a disk or you may be able 124 00:06:48,080 --> 00:06:51,160 Speaker 1: to download one off the web, and then you're ready 125 00:06:51,160 --> 00:06:53,919 Speaker 1: to go. You can just plug it and play. That's 126 00:06:54,000 --> 00:06:58,240 Speaker 1: the common turn of phrase, I guess for that. But uh, 127 00:06:59,000 --> 00:07:02,039 Speaker 1: the other neat thing, as you can connect way more 128 00:07:02,160 --> 00:07:05,160 Speaker 1: devices to your computer than you could if you had 129 00:07:05,200 --> 00:07:08,760 Speaker 1: to depend on you know, individual plugs and ports, right, 130 00:07:09,320 --> 00:07:12,320 Speaker 1: that's right. In fact, um, you can include up to 131 00:07:12,360 --> 00:07:18,680 Speaker 1: a D twenty seven with USB. That's a lot of devices. Now, um, 132 00:07:18,720 --> 00:07:20,920 Speaker 1: those of you who are listening probably caught the fact 133 00:07:20,960 --> 00:07:22,800 Speaker 1: that I said printer for the Amiga and that would 134 00:07:22,800 --> 00:07:24,840 Speaker 1: actually have been on the parallel port. So don't write 135 00:07:24,840 --> 00:07:27,040 Speaker 1: in and tell me that. But say, um, say I 136 00:07:27,080 --> 00:07:29,840 Speaker 1: did have a device I wanted to plug in via this, guys, 137 00:07:29,840 --> 00:07:32,760 Speaker 1: report to Miamiga. See if you plug in a printer 138 00:07:33,480 --> 00:07:36,760 Speaker 1: using USB on a modern computer PC or Mac, it's 139 00:07:36,800 --> 00:07:41,320 Speaker 1: going to automatically assign, uh that a number from one 140 00:07:41,360 --> 00:07:45,760 Speaker 1: to one seven, I guess um. On Miamiga, I would 141 00:07:45,760 --> 00:07:48,640 Speaker 1: have had to have actually assigned a number on myself. 142 00:07:49,040 --> 00:07:51,040 Speaker 1: So on the back of those devices there would be 143 00:07:51,040 --> 00:07:53,320 Speaker 1: a little counter. It looks like those counters that you 144 00:07:53,440 --> 00:07:56,400 Speaker 1: hand holding your hand when somebody's walking through the turnstiles 145 00:07:56,400 --> 00:07:58,480 Speaker 1: and you're actually doing a manual count. So whenever a 146 00:07:58,480 --> 00:08:00,120 Speaker 1: girl winks at me and I hit the little and 147 00:08:00,280 --> 00:08:04,840 Speaker 1: that thing, yeah, that's the one. Uh. It's actually it's 148 00:08:04,840 --> 00:08:06,800 Speaker 1: actually very much like that though. It has that that 149 00:08:06,920 --> 00:08:08,680 Speaker 1: digit counter. So you plug it in and you have 150 00:08:08,720 --> 00:08:11,000 Speaker 1: to assign it a number yourself from one to eight. 151 00:08:12,040 --> 00:08:17,400 Speaker 1: So here again USB hundred twenty seven versus very you know, 152 00:08:17,480 --> 00:08:21,800 Speaker 1: a manually assigned eight. So huge advantage. And I know 153 00:08:21,840 --> 00:08:24,360 Speaker 1: what some of you are thinking. Some of you are thinking, 154 00:08:24,560 --> 00:08:28,320 Speaker 1: how can I but Jonathan and Chris, my computer only 155 00:08:28,360 --> 00:08:31,920 Speaker 1: has one or two USB ports? How could I possibly 156 00:08:31,960 --> 00:08:34,800 Speaker 1: hook up as many as one and twenty seven devices? 157 00:08:35,480 --> 00:08:38,320 Speaker 1: Well you couldn't directly, but if you used what we 158 00:08:38,400 --> 00:08:41,319 Speaker 1: call hubs USB hubs, you could do that. In the 159 00:08:41,400 --> 00:08:44,680 Speaker 1: hub essentially plugs into your computer and it divides that 160 00:08:44,960 --> 00:08:48,600 Speaker 1: connection into further ports. Most of them are like four 161 00:08:48,720 --> 00:08:52,280 Speaker 1: ports hubs, and but you can get eight or even more. 162 00:08:52,559 --> 00:08:56,520 Speaker 1: You can find some that that divided into into larger numbers. 163 00:08:56,600 --> 00:09:00,320 Speaker 1: And by hooking hubs to hubs, you then increase, you know, 164 00:09:00,400 --> 00:09:03,520 Speaker 1: the number of ports that you can plug things into. Plus, 165 00:09:03,559 --> 00:09:08,079 Speaker 1: some peripherals like keyboards sometimes have additional USB ports on them, 166 00:09:08,200 --> 00:09:10,640 Speaker 1: or monitors if you're using a desktop computer, a lot 167 00:09:10,640 --> 00:09:13,800 Speaker 1: of monitors now have additional USB ports plug into them, 168 00:09:13,800 --> 00:09:16,719 Speaker 1: so you can use those. So yeah, just by by 169 00:09:16,840 --> 00:09:19,760 Speaker 1: adding all these hubs you can you can connect tons 170 00:09:19,760 --> 00:09:22,520 Speaker 1: and tons of devices to your computer. Uh. The other 171 00:09:22,600 --> 00:09:27,160 Speaker 1: neat thing is that that that that devices can pull 172 00:09:27,200 --> 00:09:30,720 Speaker 1: power from your computer. There are powered and unpowered devices. 173 00:09:31,000 --> 00:09:33,800 Speaker 1: Uh the USB chord if you were to cut one open, 174 00:09:33,960 --> 00:09:37,719 Speaker 1: don't do it, but if you were, you would find 175 00:09:37,760 --> 00:09:40,560 Speaker 1: out that there are there was it. I think it's 176 00:09:40,600 --> 00:09:43,520 Speaker 1: five wires in it or is it four? No, it's 177 00:09:43,559 --> 00:09:46,160 Speaker 1: got it's got two wires for power and a twisted pair. 178 00:09:47,120 --> 00:09:50,319 Speaker 1: It's more added five more for USB three. That's why 179 00:09:50,320 --> 00:09:53,320 Speaker 1: I'm saying that's the thing um about that is that 180 00:09:53,400 --> 00:09:57,000 Speaker 1: they had to change the wiring. Yeah. But USB two, 181 00:09:57,000 --> 00:09:59,800 Speaker 1: which is the common standard right now, there are four 182 00:10:00,040 --> 00:10:02,760 Speaker 1: wires within the cable. Uh so yeah, you've got you've 183 00:10:02,760 --> 00:10:06,600 Speaker 1: got a pair that provides the transfer of data and 184 00:10:06,640 --> 00:10:08,840 Speaker 1: then you have a pair that that's for the power. 185 00:10:08,880 --> 00:10:11,880 Speaker 1: So you've got a power in the ground essentially. Um 186 00:10:11,960 --> 00:10:15,320 Speaker 1: so the power right, and it's five volts. I know 187 00:10:15,400 --> 00:10:18,679 Speaker 1: that five volts of power for USB two point oh 188 00:10:18,720 --> 00:10:21,559 Speaker 1: and uh so yeah, you can you can actually power 189 00:10:21,559 --> 00:10:24,360 Speaker 1: your devices. You can charge them through your computer. Um 190 00:10:24,400 --> 00:10:26,960 Speaker 1: they're actually drawing power from your computer to the device. 191 00:10:27,520 --> 00:10:31,080 Speaker 1: And uh and so you can get hubs that are 192 00:10:31,120 --> 00:10:33,760 Speaker 1: powered as well. Um, where you would actually plug the 193 00:10:33,840 --> 00:10:36,120 Speaker 1: hub in so that way you don't you know, overload 194 00:10:36,160 --> 00:10:39,800 Speaker 1: your computer with a hundred twenty seven devices all trying 195 00:10:39,840 --> 00:10:43,160 Speaker 1: to pull power from your poor little laptop or whatever 196 00:10:43,200 --> 00:10:45,640 Speaker 1: you're using. Yeah, it depends on it depends on what 197 00:10:45,679 --> 00:10:48,680 Speaker 1: you're doing. If you're plugging in a mouse, Um, it's 198 00:10:48,720 --> 00:10:51,280 Speaker 1: going to draw a power from the computer. But if 199 00:10:51,280 --> 00:10:54,839 Speaker 1: you're plugging in something more substantial, say a printer, that's 200 00:10:54,840 --> 00:10:57,439 Speaker 1: not gonna be able to pull the power from the computer. 201 00:10:57,480 --> 00:10:59,320 Speaker 1: It's going to need its own power. Now, in the 202 00:10:59,320 --> 00:11:01,680 Speaker 1: case of a a printer, it's got its own power supply. 203 00:11:01,800 --> 00:11:03,960 Speaker 1: You you plug it into the wall. But what say 204 00:11:04,000 --> 00:11:06,800 Speaker 1: you have you know you're you're gonna work in garage, 205 00:11:06,840 --> 00:11:09,920 Speaker 1: band or something else where you want to plug in 206 00:11:10,160 --> 00:11:15,640 Speaker 1: a keyboard electronic music keyboard, not a typing keyboard. Um, 207 00:11:15,720 --> 00:11:18,640 Speaker 1: you're gonna need another source of power. And if you 208 00:11:18,679 --> 00:11:20,600 Speaker 1: have a powered hub that can that can help out 209 00:11:20,600 --> 00:11:25,960 Speaker 1: with some of those sort of in between uh peripherals. Yeah, 210 00:11:26,280 --> 00:11:29,280 Speaker 1: and um let's see what else can we talk about 211 00:11:29,360 --> 00:11:31,880 Speaker 1: USB before we move on to FireWire and then USB 212 00:11:32,040 --> 00:11:34,360 Speaker 1: three point Well, I was going to talk about how 213 00:11:35,160 --> 00:11:38,280 Speaker 1: how far you can get away because USB cable can 214 00:11:38,320 --> 00:11:41,920 Speaker 1: be about five meters from the source. Right, you can 215 00:11:41,960 --> 00:11:44,600 Speaker 1: extend that a power to hub has that used too, 216 00:11:44,640 --> 00:11:47,400 Speaker 1: because uh it can extend up to UM up to 217 00:11:47,440 --> 00:11:50,520 Speaker 1: thirty meters away. Okay. And also we should point out, 218 00:11:50,559 --> 00:11:53,040 Speaker 1: like we mentioned before, the computer acts as a host, 219 00:11:53,520 --> 00:11:58,000 Speaker 1: so each device is ultimately connecting directly to the computer. UH. 220 00:11:58,040 --> 00:12:01,199 Speaker 1: That's important for us to to note because even though 221 00:12:01,640 --> 00:12:05,000 Speaker 1: the hub might provide a node or whatever you know, 222 00:12:05,160 --> 00:12:08,560 Speaker 1: connect a further connection, but ultimately the device is interacting 223 00:12:08,559 --> 00:12:10,839 Speaker 1: directly with the computer, not with other devices that are 224 00:12:10,880 --> 00:12:14,040 Speaker 1: on your UM uh that are hooked up through the 225 00:12:14,120 --> 00:12:16,440 Speaker 1: USB ports. That's important to note because when we talk 226 00:12:16,480 --> 00:12:20,360 Speaker 1: about FireWire, things change, it's different. Um. But we should 227 00:12:20,360 --> 00:12:22,480 Speaker 1: also talk about the speeds. That's true. I was going 228 00:12:22,520 --> 00:12:24,560 Speaker 1: to say, this is the part at which we actually 229 00:12:24,559 --> 00:12:27,920 Speaker 1: address the guts of the question. Right. So USB one 230 00:12:28,000 --> 00:12:31,520 Speaker 1: point one when that came out, the speed of data 231 00:12:31,520 --> 00:12:34,719 Speaker 1: transfer was around twelve megabits per second. Right, it's got 232 00:12:34,720 --> 00:12:37,880 Speaker 1: two modes one point five and twelve megabits per second, 233 00:12:39,000 --> 00:12:42,920 Speaker 1: pretty fast. But USB two point oh was four hundred 234 00:12:43,040 --> 00:12:46,079 Speaker 1: eighty megabits per second, which is even faster, much faster 235 00:12:46,559 --> 00:12:50,480 Speaker 1: now between USB one point one in USB two point 236 00:12:50,480 --> 00:12:53,480 Speaker 1: oh that's when we saw the introduction of FireWire. That's true, 237 00:12:53,600 --> 00:12:56,400 Speaker 1: Can I mention one more thing? Go ahead? Okay, So 238 00:12:56,480 --> 00:12:58,360 Speaker 1: the other the other part of of this, and it 239 00:12:58,440 --> 00:13:00,880 Speaker 1: sort of ties back into the hubs. I've got a 240 00:13:01,080 --> 00:13:03,720 Speaker 1: USB one point one hub that I got from my 241 00:13:03,800 --> 00:13:06,240 Speaker 1: very first iMac, and I have a brand new iMac 242 00:13:06,280 --> 00:13:08,920 Speaker 1: that I got last fall. Well, now I don't have 243 00:13:09,000 --> 00:13:11,600 Speaker 1: to replace that hub. But when I plug that hub 244 00:13:11,640 --> 00:13:14,440 Speaker 1: into my computer and then I try to plug something 245 00:13:14,480 --> 00:13:18,360 Speaker 1: else that has USB two as the standard, my computer 246 00:13:18,440 --> 00:13:21,880 Speaker 1: immediately goes, hey, you know, since this is a one 247 00:13:21,920 --> 00:13:25,640 Speaker 1: point one hub, I can't send for eighty megabits per 248 00:13:25,679 --> 00:13:27,959 Speaker 1: second down this line. Are you sure you really want 249 00:13:28,000 --> 00:13:30,280 Speaker 1: to do that? See, it works fine, It will transfer 250 00:13:30,360 --> 00:13:33,240 Speaker 1: data fine, just at the speeds of one point one 251 00:13:33,280 --> 00:13:35,520 Speaker 1: as opposed to point out exactly so, if you were 252 00:13:35,520 --> 00:13:37,520 Speaker 1: going to try to plug in your iPod and sink 253 00:13:37,559 --> 00:13:40,520 Speaker 1: it with your computer, it's not going to be able 254 00:13:40,520 --> 00:13:44,800 Speaker 1: to transfer songs, movies, etcetera. Nearly as fast if you're 255 00:13:44,880 --> 00:13:48,199 Speaker 1: throttling it by putting it through a one point one hub. 256 00:13:48,720 --> 00:13:52,000 Speaker 1: But that's that's basically the difference. It doesn't render it inoperable, 257 00:13:52,000 --> 00:13:56,040 Speaker 1: It just slows it right, it's it's backward compatible. So 258 00:13:56,200 --> 00:13:59,400 Speaker 1: USB two point oh will work with USB one point 259 00:13:59,480 --> 00:14:03,600 Speaker 1: one UM devices or cables, whatever, whichever one you're looking at. 260 00:14:03,640 --> 00:14:05,920 Speaker 1: So if you've got a device that has that only 261 00:14:05,920 --> 00:14:08,400 Speaker 1: works on USB one point one and you plug it 262 00:14:08,440 --> 00:14:10,800 Speaker 1: into a port that's USB two point oh, you should 263 00:14:10,800 --> 00:14:12,760 Speaker 1: still be okay, You're just gonna be going at that 264 00:14:12,880 --> 00:14:16,120 Speaker 1: lower speed. Um. You know, for for it to go 265 00:14:16,160 --> 00:14:18,960 Speaker 1: at the higher speed, everything needs to be ready, you know, 266 00:14:19,120 --> 00:14:23,720 Speaker 1: capable of performing at the highest of the standards. So technically, 267 00:14:23,800 --> 00:14:25,800 Speaker 1: right now, we could say that's USB three point oh, 268 00:14:25,920 --> 00:14:28,040 Speaker 1: although you aren't going to find a lot of devices 269 00:14:28,040 --> 00:14:30,640 Speaker 1: and or computers that can do that right now. But 270 00:14:30,760 --> 00:14:34,160 Speaker 1: if you did have a USB three point oh capable 271 00:14:34,200 --> 00:14:39,120 Speaker 1: computer chord and device, then you could transfer at the 272 00:14:39,160 --> 00:14:42,320 Speaker 1: top speed. And you wanted to talk to talk about FireWire, 273 00:14:42,360 --> 00:14:44,720 Speaker 1: which was actually in development around the same time as 274 00:14:44,840 --> 00:14:49,320 Speaker 1: USB and supposed to be a solution to the same problem. Right, 275 00:14:49,560 --> 00:14:52,960 Speaker 1: So we're talking. You know, there's certain devices that tend 276 00:14:53,000 --> 00:14:56,440 Speaker 1: to create very large files that you may want to 277 00:14:56,440 --> 00:15:00,000 Speaker 1: transfer to a computer at some point, and the obvious 278 00:15:00,000 --> 00:15:05,480 Speaker 1: example of that is a camera, like exactly, so you're 279 00:15:05,520 --> 00:15:09,200 Speaker 1: taking these pictures or you're taking video and this. These 280 00:15:09,200 --> 00:15:11,480 Speaker 1: tend to generate very large file sizes and it could 281 00:15:11,480 --> 00:15:14,560 Speaker 1: take a very long time to transfer if you're you know, 282 00:15:14,600 --> 00:15:17,960 Speaker 1: if you have to do it through normal cables. So 283 00:15:18,440 --> 00:15:21,240 Speaker 1: FireWire was one of those solutions. And UM, I believe 284 00:15:21,280 --> 00:15:23,920 Speaker 1: Apple was behind the development of that, wasn't it. That's true, 285 00:15:23,960 --> 00:15:26,840 Speaker 1: But they weren't alone. They had other people in there 286 00:15:26,840 --> 00:15:30,400 Speaker 1: with him, including IBM. There you go. Um So, from 287 00:15:30,440 --> 00:15:32,680 Speaker 1: from what I read anyway, so USB one point one 288 00:15:32,720 --> 00:15:36,080 Speaker 1: comes out, that's one of the possible solutions to this problem. 289 00:15:36,200 --> 00:15:40,680 Speaker 1: FireWire comes out shortly thereafter. FireWire had much faster speed 290 00:15:40,880 --> 00:15:43,160 Speaker 1: than um us BE one point one, so we're looking 291 00:15:43,160 --> 00:15:45,120 Speaker 1: at twelve megabits per second at the top speed for 292 00:15:45,200 --> 00:15:48,120 Speaker 1: one point one. FireWire four hundred which was the first 293 00:15:48,120 --> 00:15:50,040 Speaker 1: one to come out, and that was four hundred megabits 294 00:15:50,040 --> 00:15:54,400 Speaker 1: per second. Wow, how aptly named? Yes, how do you 295 00:15:54,560 --> 00:15:58,760 Speaker 1: what do you know? FireWire four hundred, um and FireWire 296 00:15:59,320 --> 00:16:02,240 Speaker 1: shared a lot of other similarities with the USB. You 297 00:16:02,280 --> 00:16:05,080 Speaker 1: could you could hook up many different devices to a computer, 298 00:16:05,320 --> 00:16:08,440 Speaker 1: not as many as USB. USB was a D twenty seven, 299 00:16:08,720 --> 00:16:14,480 Speaker 1: FireWire was sixty three. Another big difference is that unlike USB, 300 00:16:14,680 --> 00:16:17,520 Speaker 1: where you had where each device was ultimately hooked to 301 00:16:17,680 --> 00:16:21,600 Speaker 1: a computer, and FireWire you could hook to fireware devices 302 00:16:21,640 --> 00:16:24,680 Speaker 1: to each other. And so it's the difference between a 303 00:16:24,880 --> 00:16:29,120 Speaker 1: a host and client relationship and appear to peer relationship. 304 00:16:29,800 --> 00:16:33,640 Speaker 1: So whereas you you could think of M A A, 305 00:16:34,200 --> 00:16:36,800 Speaker 1: let's think of a think about like a USB hub 306 00:16:36,880 --> 00:16:40,320 Speaker 1: as a bunch of spokes that all ultimately end at 307 00:16:40,320 --> 00:16:43,080 Speaker 1: the computer on one end and on a device on 308 00:16:43,120 --> 00:16:47,120 Speaker 1: the other end. Okay, so FireWire you could actually daisy 309 00:16:47,240 --> 00:16:50,120 Speaker 1: chain the devices. You could hook one device to another 310 00:16:50,560 --> 00:16:52,920 Speaker 1: and then with a second cable, hook that device to 311 00:16:53,000 --> 00:16:56,240 Speaker 1: a third device, and then hook that device to say 312 00:16:56,280 --> 00:16:59,240 Speaker 1: a computer, and all of these could transfer data back 313 00:16:59,280 --> 00:17:02,520 Speaker 1: and forth, so you didn't have to have a whole 314 00:17:02,560 --> 00:17:04,880 Speaker 1: bunch of direct connections going to the computer. That's another 315 00:17:04,880 --> 00:17:08,720 Speaker 1: one of the big differences. UM and uh there. The 316 00:17:08,840 --> 00:17:12,359 Speaker 1: cable was also slightly different. UM. It had six wires 317 00:17:12,359 --> 00:17:16,440 Speaker 1: in it instead of four the FireWire cable had. UM 318 00:17:16,640 --> 00:17:20,240 Speaker 1: had two for power and two twisted pair sets for 319 00:17:20,320 --> 00:17:23,399 Speaker 1: data transfers instead of just the single twisted pair set 320 00:17:23,520 --> 00:17:29,440 Speaker 1: for the USB had UM. So this was Apple really 321 00:17:29,440 --> 00:17:32,040 Speaker 1: pushed this. This and put it in a lot of 322 00:17:32,040 --> 00:17:35,399 Speaker 1: their products for a really long time, and then until 323 00:17:35,480 --> 00:17:38,880 Speaker 1: just recently they started to kind of back off of it. Well, 324 00:17:38,880 --> 00:17:41,359 Speaker 1: they still have it available on on a lot of 325 00:17:41,359 --> 00:17:44,560 Speaker 1: the high end computers, but they're sort of backing off. 326 00:17:45,359 --> 00:17:48,280 Speaker 1: And although they did come out with a second version 327 00:17:48,320 --> 00:17:51,120 Speaker 1: of that called um, you know, you're never gonna get 328 00:17:51,160 --> 00:17:54,800 Speaker 1: this FireWire eight. Wait, let me guess how fast it went? 329 00:17:55,640 --> 00:17:59,160 Speaker 1: Eight hundred megabits per second. I can't put anything past you, yea, 330 00:18:00,000 --> 00:18:02,840 Speaker 1: So yes, you know it's it's it's very efficient. Um, 331 00:18:02,920 --> 00:18:05,080 Speaker 1: slightly different, the connector is a little different, but it 332 00:18:05,160 --> 00:18:07,919 Speaker 1: is it does work essentially the same way and you know, 333 00:18:08,480 --> 00:18:11,560 Speaker 1: just faster. So yeah, let's sea if we're looking at 334 00:18:11,560 --> 00:18:14,680 Speaker 1: the timeline. Then USB one point one comes out, FireWire 335 00:18:14,680 --> 00:18:17,560 Speaker 1: four hunter comes out, blows away the speed for USB 336 00:18:17,680 --> 00:18:20,520 Speaker 1: one point one. USB two point oh comes out. It's 337 00:18:20,560 --> 00:18:24,440 Speaker 1: actually a little faster than FireWire. FireWire a hundred comes out, 338 00:18:24,520 --> 00:18:27,080 Speaker 1: and it's almost twice as fast as USB two point oh. 339 00:18:27,280 --> 00:18:31,399 Speaker 1: So for competition, yeah, but then again, at this point 340 00:18:31,400 --> 00:18:36,440 Speaker 1: you're dealing with USB and FireWire versus serial parallel, Scuzzy 341 00:18:36,760 --> 00:18:40,040 Speaker 1: A d B, you know, all those other ports so 342 00:18:40,119 --> 00:18:43,720 Speaker 1: now we're just down to two connectors, which is much nicer. Yeah, 343 00:18:43,760 --> 00:18:46,920 Speaker 1: and really when you look at most computers, you're really 344 00:18:46,960 --> 00:18:50,000 Speaker 1: done to one connector pretty much now because USB has 345 00:18:50,200 --> 00:18:53,840 Speaker 1: essentially one this this format battle UM all but one it. 346 00:18:53,920 --> 00:18:57,159 Speaker 1: I mean, there's still people who who work in video 347 00:18:57,920 --> 00:19:01,280 Speaker 1: UM that prefer FireWire because a lot of video cameras 348 00:19:01,320 --> 00:19:05,399 Speaker 1: that that's that's the the format they use. Well, Sony 349 00:19:05,560 --> 00:19:07,679 Speaker 1: was a big proponent of it, but of course Apple 350 00:19:07,760 --> 00:19:11,240 Speaker 1: owned the FireWire names, so Sony used eyelink or I 351 00:19:11,400 --> 00:19:13,959 Speaker 1: got link um, you know, and a lot of other 352 00:19:14,000 --> 00:19:17,680 Speaker 1: people called it by its standard name, which the Institute 353 00:19:17,720 --> 00:19:22,720 Speaker 1: of Electrical and Electronics Engineers actually they use I triple 354 00:19:22,760 --> 00:19:26,320 Speaker 1: E says it on the website. But yeah, I E. 355 00:19:28,119 --> 00:19:31,280 Speaker 1: If you see that, that's FireWire, so um Yeah, very 356 00:19:31,359 --> 00:19:36,640 Speaker 1: very popular with UM with video camera enthusiasts. But yeah, 357 00:19:36,680 --> 00:19:39,399 Speaker 1: I think I think things are moving towards USB only 358 00:19:39,640 --> 00:19:44,240 Speaker 1: or even Bluetooth. Now. There's still there's still some development 359 00:19:44,240 --> 00:19:46,560 Speaker 1: on the FireWire front. I know that there there's a 360 00:19:46,560 --> 00:19:50,600 Speaker 1: push to to pull out another yet another new standard 361 00:19:50,640 --> 00:19:54,359 Speaker 1: for FireWire, which I think would transferred data an excess 362 00:19:54,480 --> 00:19:57,720 Speaker 1: of six gigabits per second. That's funny. You should mention 363 00:19:57,800 --> 00:20:02,960 Speaker 1: six gigabits this. Other people are are doing that too. Yeah, yeah, like, Um, 364 00:20:03,080 --> 00:20:07,280 Speaker 1: the E S A T A transfer standard. Um, it's 365 00:20:07,320 --> 00:20:10,359 Speaker 1: it's less popular than the other two, but it is 366 00:20:10,440 --> 00:20:13,960 Speaker 1: probably the the last of the holdouts, I guess. Of 367 00:20:14,040 --> 00:20:16,359 Speaker 1: course S A T A is a popular standard for 368 00:20:16,640 --> 00:20:20,399 Speaker 1: internally mounting components on a computer. Um, but there is 369 00:20:20,440 --> 00:20:22,439 Speaker 1: an external connector and you see you do see that 370 00:20:22,520 --> 00:20:26,119 Speaker 1: on some pecs in different places. Um, but that the 371 00:20:26,440 --> 00:20:29,080 Speaker 1: current standard for UH for S A T A is 372 00:20:29,359 --> 00:20:34,040 Speaker 1: six gigabit per second. But USB three is approaching that. Yeah, 373 00:20:34,080 --> 00:20:37,640 Speaker 1: it's not quite it's not. It's in four point eight 374 00:20:37,640 --> 00:20:40,720 Speaker 1: gigabits per second, which if you look at the USB 375 00:20:40,800 --> 00:20:43,359 Speaker 1: two point oh, that's ten times faster. I was going 376 00:20:43,400 --> 00:20:47,200 Speaker 1: to say that falls into the nothing to sneeze at category. Yes, yes, 377 00:20:47,240 --> 00:20:49,159 Speaker 1: if you were to sneeze it that you should be 378 00:20:49,200 --> 00:20:52,640 Speaker 1: reprimanded exactly, for it is nothing to sneeze at. Yes, 379 00:20:52,680 --> 00:20:56,040 Speaker 1: the USB three point oh sometimes people call it USB superspeed, 380 00:20:57,080 --> 00:21:01,119 Speaker 1: And um, they've added five line, as I was saying 381 00:21:01,119 --> 00:21:03,480 Speaker 1: earlier when I was fumbling around thinking was it four? 382 00:21:03,640 --> 00:21:06,399 Speaker 1: Was it five? But they're not all copper anymore. No, 383 00:21:06,920 --> 00:21:11,240 Speaker 1: there's fiber optics, and uh yeah, we're looking at UM 384 00:21:11,240 --> 00:21:13,400 Speaker 1: we're looking at the potential for devices to be able 385 00:21:13,440 --> 00:21:17,800 Speaker 1: to move data very very quickly. UM. Still, it's still 386 00:21:17,800 --> 00:21:21,399 Speaker 1: one of those device host arrangements. The thing I like 387 00:21:21,440 --> 00:21:24,080 Speaker 1: about FireWire is the idea of being able to share 388 00:21:24,119 --> 00:21:27,359 Speaker 1: information between two separate devices without even bringing a computer 389 00:21:27,440 --> 00:21:31,400 Speaker 1: into the picture. UM. I really do like that that capability. 390 00:21:32,040 --> 00:21:34,520 Speaker 1: I don't tend to use anything that has FireWire in it. 391 00:21:34,720 --> 00:21:37,119 Speaker 1: I just happened to think that's a that's a neat 392 00:21:37,960 --> 00:21:40,880 Speaker 1: ability to have, UM, as opposed to having to use 393 00:21:40,920 --> 00:21:45,200 Speaker 1: a computer as the middleman for all of your data transfers. UM. 394 00:21:45,280 --> 00:21:48,840 Speaker 1: But I do think that USB has become pretty much 395 00:21:48,880 --> 00:21:52,800 Speaker 1: the de facto standard across the industry, and so USB 396 00:21:52,880 --> 00:21:54,760 Speaker 1: three point has got a good chance of being the 397 00:21:55,119 --> 00:21:59,920 Speaker 1: standard for high speed data transfers between devices and your computers. 398 00:22:00,040 --> 00:22:04,200 Speaker 1: So I'm looking forward to our USB overlords. UM. I'm 399 00:22:04,200 --> 00:22:08,000 Speaker 1: sure I'll be using plenty of devices that use that standard. 400 00:22:08,160 --> 00:22:10,000 Speaker 1: So I'm gonna hit you with a question that you 401 00:22:10,080 --> 00:22:14,240 Speaker 1: probably weren't expecting. How good, So I assume that USB 402 00:22:14,400 --> 00:22:17,560 Speaker 1: three point I will be backward compatible. Also and that 403 00:22:17,600 --> 00:22:21,200 Speaker 1: you will be able to use your USB one point 404 00:22:21,200 --> 00:22:24,560 Speaker 1: one or USB two hub if you want to, or 405 00:22:24,640 --> 00:22:26,520 Speaker 1: you know, it's just gonna be slow. I know the 406 00:22:26,600 --> 00:22:31,080 Speaker 1: connectors are a little different. So I'm not entirely sure 407 00:22:31,119 --> 00:22:35,560 Speaker 1: that you could plug a USB three chord. You haven't. No, 408 00:22:35,720 --> 00:22:40,440 Speaker 1: they're pretty. Oh they're not pretty. It's a chord, it's 409 00:22:40,480 --> 00:22:43,760 Speaker 1: a cable. Actually, the ones I saw were blue. Um. Yeah, 410 00:22:43,760 --> 00:22:47,359 Speaker 1: they had some at ces um. Yeah. I you know, 411 00:22:47,400 --> 00:22:50,040 Speaker 1: I didn't take a good close enough look. I don't. 412 00:22:50,119 --> 00:22:54,440 Speaker 1: I'm not entirely certain that you would be able to 413 00:22:54,440 --> 00:22:58,520 Speaker 1: to plug a USB three chord into a non USB 414 00:22:58,680 --> 00:23:02,679 Speaker 1: three device. However, I do think it's backwards compatible in 415 00:23:02,680 --> 00:23:05,280 Speaker 1: the sense that you could use a USB two chord 416 00:23:05,680 --> 00:23:09,040 Speaker 1: to connect your computer to a device. It just would 417 00:23:09,160 --> 00:23:14,400 Speaker 1: move data at the USB two speed. Um. So yeah, 418 00:23:14,440 --> 00:23:16,040 Speaker 1: if you had the if you had a USB two 419 00:23:16,119 --> 00:23:18,399 Speaker 1: chord and a USB two device, you could they you 420 00:23:18,400 --> 00:23:21,440 Speaker 1: could plug it into your computer to a USB three chord. 421 00:23:21,520 --> 00:23:24,160 Speaker 1: You're gonna need a USB three device because the end 422 00:23:24,160 --> 00:23:28,800 Speaker 1: that plugs into your device is going to be different. Okay, Yeah, 423 00:23:29,000 --> 00:23:31,040 Speaker 1: was that the question or were you leading up to something. 424 00:23:32,480 --> 00:23:34,159 Speaker 1: It's like, well, you know, all right, now hit me 425 00:23:34,160 --> 00:23:39,479 Speaker 1: with your question. I had a Mexican for lunch in 426 00:23:39,520 --> 00:23:43,280 Speaker 1: case that was another question, Just in case. That's all 427 00:23:43,320 --> 00:23:46,880 Speaker 1: I've got. That's all you got. Awesome, fantastic. That's all 428 00:23:46,880 --> 00:23:50,680 Speaker 1: I've got to except um, oh, well, you know, there's 429 00:23:50,720 --> 00:23:54,000 Speaker 1: one other thing we could talk about very briefly. There's 430 00:23:54,040 --> 00:23:58,080 Speaker 1: one other standard that's in development that we may see 431 00:23:58,160 --> 00:24:00,760 Speaker 1: or we may never see, which is why or less USB, 432 00:24:01,200 --> 00:24:05,360 Speaker 1: which I find to be sort of oxymoronic. Yeah, kind 433 00:24:05,400 --> 00:24:08,480 Speaker 1: of um. And and from what I understand, most of 434 00:24:08,480 --> 00:24:10,879 Speaker 1: the wireless USB, it's and we're talking about ultra short 435 00:24:11,000 --> 00:24:15,680 Speaker 1: range data transfers um and shorter than Bluetooth, shorter than YEA. Yeah, 436 00:24:15,720 --> 00:24:18,960 Speaker 1: we're talking about really close to to whatever devices. And 437 00:24:18,960 --> 00:24:22,560 Speaker 1: here's the other thing about wireless USB. There's one important 438 00:24:22,600 --> 00:24:26,000 Speaker 1: component of USB that you cannot achieve wirelessly as of 439 00:24:26,119 --> 00:24:28,640 Speaker 1: right now. The plug. How would be it? The power? 440 00:24:29,119 --> 00:24:33,159 Speaker 1: Because um, even Tesla has not figured out how to 441 00:24:33,200 --> 00:24:37,119 Speaker 1: do that. Um. Yeah, broadcasting power back and forth between 442 00:24:37,119 --> 00:24:40,520 Speaker 1: your device and the computer is not not really possible 443 00:24:40,680 --> 00:24:44,959 Speaker 1: right now. So, um, that part of the USB equation 444 00:24:45,359 --> 00:24:47,960 Speaker 1: is null and void when you're talking about wireless us B. 445 00:24:48,560 --> 00:24:50,600 Speaker 1: So if you had a wireless USB mouse, you'd have 446 00:24:50,640 --> 00:24:52,600 Speaker 1: to have some kind of battery power going on in 447 00:24:52,600 --> 00:24:56,840 Speaker 1: the mouse in order for you to use that device. Yeah, yeah, 448 00:24:56,880 --> 00:25:01,480 Speaker 1: And I mean I've I've got a wireless I've got 449 00:25:01,520 --> 00:25:04,359 Speaker 1: a wireless mouse, but it's not a USB mouse, so 450 00:25:04,400 --> 00:25:06,879 Speaker 1: and of course it has the as a docking station 451 00:25:06,960 --> 00:25:09,480 Speaker 1: sort of thing that actually plugs into the computer, so 452 00:25:09,480 --> 00:25:14,399 Speaker 1: it's not yeah, kind of like a dongle, dongle the 453 00:25:14,440 --> 00:25:18,800 Speaker 1: French called dongle um. But yeah, that's that's that. I 454 00:25:18,840 --> 00:25:23,240 Speaker 1: hope that answers your question, Leanna. The really, when you're 455 00:25:23,240 --> 00:25:27,000 Speaker 1: looking at USB, you're just looking at moving data back 456 00:25:27,000 --> 00:25:30,400 Speaker 1: and forth between devices and computers. You shouldn't need any 457 00:25:30,440 --> 00:25:32,440 Speaker 1: sort of adapter. I mean, if you are using an 458 00:25:32,440 --> 00:25:35,560 Speaker 1: old hub that's plugged into your computer and you're you 459 00:25:35,600 --> 00:25:37,720 Speaker 1: realize that it's taking a really long time to move data, 460 00:25:37,720 --> 00:25:39,320 Speaker 1: it might be time to buy a new hub, because 461 00:25:39,320 --> 00:25:40,800 Speaker 1: it may be that the hub you've got is a 462 00:25:40,880 --> 00:25:44,880 Speaker 1: USB one point one and that would be the problem. 463 00:25:44,960 --> 00:25:46,600 Speaker 1: But if you know, as as long as everything is 464 00:25:46,600 --> 00:25:49,080 Speaker 1: that USB two point oh, then you know you're gonna 465 00:25:49,119 --> 00:25:51,760 Speaker 1: you're gonna move at pretty good speeds. There you go. 466 00:25:52,280 --> 00:25:55,439 Speaker 1: So this. Um, this brings us round to uh our 467 00:25:55,560 --> 00:26:04,679 Speaker 1: second bout of listener made oh man, So this comes 468 00:26:04,720 --> 00:26:09,840 Speaker 1: from Jesse. Hey, guys, I just wanted to say, while 469 00:26:09,880 --> 00:26:13,480 Speaker 1: I love the last podcast technology we can thank NASA for, 470 00:26:14,080 --> 00:26:16,280 Speaker 1: I must admit that I was very disappointed at the 471 00:26:16,320 --> 00:26:19,280 Speaker 1: list of inventions. While many of these are great ideas 472 00:26:19,520 --> 00:26:22,919 Speaker 1: and benefit mankind in a nonchalant way, I found I 473 00:26:22,960 --> 00:26:27,200 Speaker 1: was eager to hear about great world changing advances. Unfortunately, 474 00:26:27,240 --> 00:26:31,520 Speaker 1: the hype climax somewhere near the mention of a space pen. 475 00:26:32,359 --> 00:26:36,080 Speaker 1: Although extremely entertaining, if I am maybe cliche, it isn't 476 00:26:36,080 --> 00:26:38,919 Speaker 1: the sort of thing it takes a rocket scientist to 477 00:26:38,960 --> 00:26:43,879 Speaker 1: figure out. Anyways, Thanks for the entertaining podcast. Well, Jesse, Um, 478 00:26:43,880 --> 00:26:45,520 Speaker 1: we thought about this, and you know, we were really 479 00:26:45,560 --> 00:26:48,160 Speaker 1: looking at different technologies that benefit us on a day 480 00:26:48,160 --> 00:26:50,159 Speaker 1: to day basis and the kind of things that you know, 481 00:26:50,200 --> 00:26:53,159 Speaker 1: we might not have if we didn't have NASA. But 482 00:26:53,200 --> 00:26:56,760 Speaker 1: if you want something that's really world changing, how about 483 00:26:57,480 --> 00:27:00,280 Speaker 1: a ship that can take a man to the a 484 00:27:00,400 --> 00:27:05,600 Speaker 1: freaking moon. That sounds pretty advanced. Yeah, yeah, that would 485 00:27:05,600 --> 00:27:07,960 Speaker 1: be a big one, I would say, UM, lots of 486 00:27:08,000 --> 00:27:11,120 Speaker 1: other ones big The communication satellites. We actually mentioned that. 487 00:27:11,640 --> 00:27:15,439 Speaker 1: And the ship that can launch and then return like 488 00:27:15,560 --> 00:27:18,760 Speaker 1: a plane. Yeah, another big one. Um. Yeah, there's some 489 00:27:18,960 --> 00:27:22,000 Speaker 1: there's some pretty decent inventions masses made that have been 490 00:27:22,000 --> 00:27:25,399 Speaker 1: world changing. Um and you know who who Who's to 491 00:27:25,480 --> 00:27:30,119 Speaker 1: say that the smaller quote unquote inventions haven't changed the 492 00:27:30,160 --> 00:27:33,600 Speaker 1: world in some fundamental way. We wouldn't know unless we 493 00:27:33,600 --> 00:27:35,400 Speaker 1: were able to look in on a world that did 494 00:27:35,440 --> 00:27:38,199 Speaker 1: not have those inventions, now would we? And I have 495 00:27:38,280 --> 00:27:40,040 Speaker 1: one of those inventions, but I'm not sharing it with 496 00:27:40,119 --> 00:27:43,680 Speaker 1: the rest of you. Ha ha ha. So if any 497 00:27:43,760 --> 00:27:46,199 Speaker 1: of you want to be mocked by tech stuff, please 498 00:27:46,320 --> 00:27:49,360 Speaker 1: write to tex Stuff at how stuff works dot com. 499 00:27:50,040 --> 00:27:52,000 Speaker 1: Uh no, we won't really mock you.
