This is less than 7.3 multipurpose cables, part one
00:04
USB, thunderbolt and lightning. So it's going to get started.
00:08
Okay, so what we're gonna do in this lesson Part one and part two, we're going to step through and talk about different multipurpose cables. So in part one, we're going to talk about us. Be the different varieties of us, be
00:22
U S B C. The mini USB micro, USB. We're gonna finish talking about Thunder Boat and the Lightning cable
00:30
on According to the company A plus, these are all on the county, a plus exam and for the 2 to 0 dash ones or one. So let's go ahead and march through these and get you up to speed on these cables.
00:44
So let's first talk about USB. Everyone knows about us be. It's probably one of the most common connectors nowadays. It connects pretty much almost every common peripheral today. Now the core of the USB is the USB host controller. It's an integrated circuit it normally built right into the chipset.
01:03
Now, the host controller of us be acts as the interface between the system and every USB device that's connected connected to it.
01:11
the USB route hub is connected to the USB controller. It makes the condition connection to each port.
01:19
Now a single USB controller can connect up to 100 and 27 USB devices. Now, theoretically, your motherboard may only have 6 to 8, sometimes even 10 USB ports, so this would be accomplished through USB hubs and so forth. So again, the USB controller can
01:38
can host up to 127 USB devices. So that's a lot of devices.
01:42
So let's go through the USB in orations. Inversion upgrades
01:47
when U. S. B first came out with the 1.0 and shortly after the one God one USB was the first widely adopted standard and divine to speeds of the low speed USB was a maximum of 1.5 megabits per second and a full speed US be running yet up to 12 megabits per second.
02:06
And the maximum cable lived. There was five meters, so 1.1 dot zero was the first iteration of us be followed by 1.1
02:15
and again, both of whom had a maximum speed of one, not five in a full speed running at 12 megabits USB two Dato introduced high speed US be running at 480 megabits. The maximum cable lived. There was five meters as well,
02:31
and after that we came out with us. Beat 3.0, and that was capable of speeds up to five gigabits per second.
02:42
Now the USB connectors were often very with the U. S. B A and B, but let's look at us be. See, that's the newest generation of the connectors on the USB line, U. S. B C is a Type C connector and uses 24 p n's,
02:55
which could be inserted in either orientation, meaning it could be up or down. It's the same either way,
03:01
not like the U. S. B. A or B. He's fully supports us be $3.1 which is I'm coming and even supports other buses such as the Apple Thunder Boat. Ah U S B C is being used universally now on you're starting stated on more mobile devices, desktops
03:21
even on mobile devices, mobile phones.
03:23
Ah, you SBC Because of its up, it's using its practicality. That you can use it in either orientation makes it a great choice. I don't know if you've ever tried using a USB port on a mobile device, and it only fits one way and you're trying to do it in the dark. That's where US Beast see comes into play.
03:40
It's either orientation, either up or down. If it's both ways
03:45
now, we're gonna take a step back and talk about other USB connectors first, starting with the mini USB
03:51
that many of the USB connectors were introduced together with the U. S B two Dato in April 2000 for use with smaller devices such as digital cameras, smartphones and tablet computers, both the many A in many be plugs are approximately three by seven millimeters or 70.12 by 0.28 inches,
04:10
and you can see on the image this is the many us being if you remember, those
04:14
with the older digital cameras and the other small form factor devices
04:19
and micro us being came out After that, which was smaller, micro USB connectors were introduced and back in January 2007. Now they have a smaller with than the mini USB, but approximately half the thickness. The micro A connector is 6.85 millimeter by 1.8 millimeter
04:39
or points to 70 by 700.71 inches.
04:44
Micro Be connector is 6.85 by 1.8 millimeter by 0.270 by 0.71 inches, and you can see right there. That's the more of the common USB port that you'll see on mobile devices nowadays and other small form factor devices.
05:03
The boat thunderbolt was an intel on Apple developed port as a high speed alternative to the existing technologies of us being FireWire, and it utilized the PC. I'II express bus for up to six external peripherals utilizing the PC. I express your guaranteed faster speeds.
05:21
Thunderbolt wanted thing about to use the same connector as the mini display Porter MDB.
05:28
You'll see that right there on the left of the image with the older Thunderbolt Port.
05:33
Now the newer Thunderbolt three that reads the same U S. B. C connector from the USB family. You can see that image right there in the meadow.
05:44
Now. The first version of Thunder Boat came in at a full duplex at 10 gigabits per second. That was the speed throughput for that version. Vulnerable to combines internal data channels, enabling throughput up to 20 gigabits per second. So that pretty much doubled the speed of the original version
06:01
and Thunderbolt three upto four gate, 40 gigabytes per second and half the power consumption off thunderbolt, too. So, as you can see, his technology advanced, power consumption went down and speed. What's up? So definitely advancement there.
06:19
And the Apple Lightning Cable. The Lightning cable is the proprietary computer bus and power connector created by Apple. It was first introduced in September 2012 and it replaced the original Apple 30 pin dot connector.
06:34
Now the lightning connector is used to connect on Apple Mobile devices, lectures, iPads, iPhones, iPods to host computers, external monitors, cameras, USB battery, chargers and other peripherals along the apple lines. So the lighting cable past his data as well as power.
06:54
So, in comparison to the US, better USB
06:57
that you use for mobile phones, same thing with his lightning cable power and data.
07:02
Okay, So just to review what we've covered today, we talked about the USB versions one dato to Dato and three notto USB. See the many us being in the micro USB and we finished off and rounded on our conversation today with the Thunder Boat and the Lightning.
07:19
So that is it for this lesson, and we will see you in the next lesson in this series.
