Video Description

Floppy drives connectors are very unique from any other connector inside of your computer. It has a 31 pin that sits on the twisted side of the connector cable with the non-twisted side fixed to the motherboard. It is a one-way connection and power component in that the connector side is a 4pin berg connector which is unique only to the floppy drive. Should you ever encounter a floppy drive whose light constantly eliminated and it doesn't read, chances are its cable is inverted with the twisted end sitting on the motherboard rather than on the floppy disk drive itself. USBs – universal serial bus – is the most commonly used connector and is used mostly for connecting to a keyboard, mouse, printer, or even mobiles devices. The USB comes in several types which denotes the differing speeds its available in. USB has a definitive symbol, so we'll diagram each show you how to identify the symbol, list the different transfer speeds for the standard USB, the Hi-Speed USB and the SuperSpeed USB. And we'll explain the differences between all the connectors that support them and how they are used.

00:04
moving on to some of our other devices will have in our computer. We're going to check out our floppy connectors now are floppy Connector
00:13
is a 34 wire
00:15
ribbon cable
00:17
that looks very similar to
00:19
our payday connectors.
00:21
But one of the very quick and obvious differences is this twist in the cable we have here. This twist in designates floppy drive in. So the end that's closer to this twist. Wanna make sure it's plugged into our floppy drive rather than a motherboard. So as we have here are floppy drive and we just simply plug our cable in here
00:40
and then our other end our non twist and it's plugged into your motherboard.
00:43
If you turn on a computer and you notice that you have a floppy drive that has a constantly illuminated light on the front,
00:50
and it's not able to read, you're not able to do anything with it. Chances are you actually have the cable inverted with the twist in toward the motherboard, so we need to open it up and check out that cable and make sure that it's pointed toward the right and so are floppy. 34 pin on Lee one way again. Its power is a four pen
01:10
Bloomberg connector
01:11
are four pin Berg connector. Is this small connector here? And we'll simply attach. This is a very unique connector for the floppy drive, and we simply attach it as such into our floppy drive. Our next
01:25
device connector and one of our Met most ticks Popular external device connectors is going to be our USB connector.
01:32
Our unit, U S. B, stands for Universal Serial Bus, and it comes in a couple different types, one of our most popular being the Type A. It's the flat, most common connector that you'll see on USB sticks or external drives, and we actually come in a couple different versions for the U. S. B. We have a U. S. B 1.1,
01:49
and this is actually gonna transfer data at 12 megabits per second.
01:52
It's simply known as just a standard USB USB two point. Oh is gonna let us transfer data at 480 megabits per second, and this is known as, ah, high speed us be when we're looking at a USB symbol will see a symbol
02:08
which looks like this with an arrow on one end a circle upon the top
02:14
and a square down on the bottom. And if we just see this symbol, this is our USB
02:20
1.1.
02:22
If we see this with a plus next to it, that's our USB high speed.
02:27
And if we see this with a S s,
02:30
that's our USB superspeed. What's our USB superspy? Our USP superspeed is our next one are us be 3.0, which allows us to transfer data up to five gigabits per second. This is our super speed. Not only are we transferring data and different iterations or 1.12 point Oh, and 3.0,
02:50
we also have a couple of different types of connectors
02:53
into our USB. We have type A and type B connectors for both our. For each of our 1.12 point Oh, in three point are type A connectors for 1.12 point. Oh, and 3.0 are going to be the same across the board. Our Taipei connectors are simply going to be our flat standard connectors with the block at one end
03:13
their pens on our other end
03:15
and will notice it as looking just like this connector here, Rus, be a connector standard flat connector are tightened. Be connector is a bit more square connector. And this tight. Be on Lee. Looks like this
03:28
for our U S. B three point. Oh, so type the four. Only 1.1 and two point. Oh, he's going to look like our connector here, and you'll most often see this on our printers will have us be a T U S B B type B,
03:45
and the Taipei will plug into your computer and the tight be will plug into your printer
03:49
are tightened, be for our USB 3.0 is a bit different connector and actually looks like more blocky square type connector
03:55
for the standard. But we also have, ah type B, many connector, which is more common. And that looks like this one. And you'll most often see this USB three point. Oh, tight, be many connector on external hard drives and this is a super speed 3.0 connector. So the Titan be standard for 3.0,
04:15
and then the tight. Be
04:16
many for three point. Oh, looks like that now, just like tight. Be for 3.0 has a standard in the mini Type A and B for all the different versions. Also have mini and micro versions. You'll commonly see USB Type A microt
04:30
on your phones, and those will be used when you need thio. Charge your phone when you need to transmit data from your phone
04:38
because having the big, blocky standard type a connector on your phone would be very unwieldy. So having the type A micro is a lot smaller, a lot easier to transmit that data and recharge your phone.
