00:00:00.160 --> 00:00:06.080
the u in usb stands for universal which

00:00:03.679 --> 00:00:10.480
is appropriate seeing as how usb devices are everywhere i mean you can even get a

00:00:08.320 --> 00:00:14.320
usb turret to shoot nerf projectiles at your irritating co-workers but one

00:00:12.320 --> 00:00:18.800
common annoyance is that there's been a plethora of usb connector types over the

00:00:16.880 --> 00:00:23.840
years making the experience not quite as universal as we'd like what's so special

00:00:21.359 --> 00:00:28.960
about usb where we can't have the same connector on both ends of the cable i

00:00:26.080 --> 00:00:33.360
mean Ethernet HDMI and good old rca jacks figured out so why can't usb take

00:00:32.079 --> 00:00:39.600
a look at this thing which you'll probably recognize if you've ever plugged in a printer over usb this is

00:00:36.880 --> 00:00:42.320
called a usb type b connector and unfortunately if you've ever needed one

00:00:40.800 --> 00:00:46.559
of these cables in a pinch there aren't a whole lot of other devices that use it

00:00:44.320 --> 00:00:50.559
meaning you probably don't just have one lying around to add insult to injury

00:00:48.800 --> 00:00:54.000
printer manufacturers usually don't include a type b cable in the box

00:00:52.559 --> 00:00:57.600
meaning you have to go out and buy one yourself so is this some kind of big

00:00:56.000 --> 00:01:02.000
racket by the electronics industry to suck more money out of you

00:00:59.520 --> 00:01:05.360
well maybe not a fundamental difference between usb and some of those other

00:01:03.840 --> 00:01:08.080
connection types we mentioned earlier is that usb carries

00:01:07.119 --> 00:01:12.320
power hence why so many usb gadgets don't need

00:01:10.560 --> 00:01:16.799
to be plugged into the wall separately but providing power on the same cable as

00:01:14.640 --> 00:01:20.640
data has the drawback that connecting things the wrong way

00:01:18.400 --> 00:01:25.920
can lead to damaged devices or other electrical hazards so the powers that be

00:01:23.119 --> 00:01:31.840
designed usb so that you always have an upstream and a downstream device with

00:01:28.960 --> 00:01:35.119
power only flowing in one direction as part of this design process different

00:01:33.600 --> 00:01:40.159
connectors were created for upstream and downstream devices the typical

00:01:37.439 --> 00:01:44.000
rectangular usb type a connector that you're used to seeing is usually on

00:01:41.759 --> 00:01:48.880
devices that provide power this is why you'll often see them on gadgets that

00:01:46.320 --> 00:01:53.040
you plug into the wall like desktop pcs and charging bricks for your smartphone

00:01:50.720 --> 00:01:57.360
the other end is often something different on purpose so that people

00:01:55.119 --> 00:02:01.920
won't try to connect two type a ports together so if for example you've ever

00:02:00.159 --> 00:02:06.799
wondered why you can't just send data between two computers by connecting them

00:02:03.680 --> 00:02:08.800
with type a to type a this is a big part

00:02:06.799 --> 00:02:11.280
of the reason why of course the standard type b

00:02:09.840 --> 00:02:16.239
that you see on a printer or something like a monitor with a usb hub or a

00:02:13.440 --> 00:02:21.360
desktop dac for you audio people is fairly bulky so the micro b connector

00:02:18.959 --> 00:02:25.440
became pretty common for small devices like smartphones that receive power you

00:02:23.760 --> 00:02:30.080
can even see this on your typical power bank where you plug in the full size

00:02:27.920 --> 00:02:34.400
type a connector when using it to charge a phone but instead plug in a micro b

00:02:32.400 --> 00:02:40.480
connector when you're recharging the power bank itself micro b was further

00:02:37.120 --> 00:02:41.840
revised once usb 3.0 was released

00:02:40.480 --> 00:02:46.879
as we saw these very funky looking connectors hit

00:02:44.239 --> 00:02:51.120
the market that extra lobe on the side enables more data to be carried making

00:02:48.959 --> 00:02:56.239
the connector compliant with higher usb 3.0 speeds but in my opinion this

00:02:53.519 --> 00:03:00.160
connector sucks they break easily and i don't like plugging them in

00:02:57.760 --> 00:03:05.920
ugly of course with the launch of usb type c as you can see here it's more

00:03:02.720 --> 00:03:08.560
common now to find a c to c cable as the

00:03:05.920 --> 00:03:13.040
usbc actually supports having two devices negotiate to determine which

00:03:11.040 --> 00:03:17.120
would be the host that provides power although this was possible with previous

00:03:14.959 --> 00:03:20.800
usb connectors with a protocol called usb on the go support for it was

00:03:19.519 --> 00:03:25.760
inconsistent however because many usbc devices need

00:03:23.200 --> 00:03:28.959
to connect to older hardware c to a cables should still be commonplace for a

00:03:27.840 --> 00:03:33.280
long time but do know that the days of juggling

00:03:31.040 --> 00:03:38.480
connectors should be numbered in the meantime you can always use your printer

00:03:35.920 --> 00:03:41.200
wirelessly oh god that sounds like a nightmare something about printers

00:03:40.159 --> 00:03:45.440
that's just never easy speaking of easy our sponsor

00:03:43.840 --> 00:03:49.120
brilliant do you want to learn something new brilliant is the place to do it

something for everybody whether you want to brush up on the basics of algebra

00:04:20.639 --> 00:04:25.680
learn programming or learn about cutting-edge topics like neural networks

00:04:24.240 --> 00:04:29.680
there's even some advanced stuff like differential equations if you're into

00:04:27.840 --> 00:04:34.000
