Hi and welcome to the camp Tia A plus 2 to +0-1001 module to in this lesson lesson to dot To form factor and sizes. The different motherboard form factors in sizes. I'm your instructor, Bill Price.
Okay, for today's lesson, we're gonna start off talking about the form factor and explain what the form factory is when we hear that in speaking of commuter computer terms
next we're gonna look at a motherboard history how we arrive, where we are today in the history of motherboards. From there, we're going to talk about for three main motherboards that the camp t A eight plus expect us the technician to know and be able to choose a different street between them, the three motherboards,
and see the benefits of each as faras in when you're configuring system or what recommendation you would make depending on a system that you're looking at and that will be the 80 x,
the micro a T X and the M I A. T X mother, many I t. X.
So let's go and get started.
First, we're gonna talk about the form factor. What is the form factor? So choosing the right motherboard is based on the purpose of system you're building. Whether the system is going to be a cat design or injured in computer, you want to choose the right board that will handle the appropriate devices that you need for that particular machine.
The next important choice would be to the would be the size of the case
that the motherboard will fit. In that case, we need to be ableto handle the various connect reports, power supply and other devices for the particular form factor motherboard.
Other considerations would be cooling for your computer. If your system you're building or a smaller system for a specific use, such as a set top box or home theater PC, you would need a smaller form factor motherboard that she would get in a smaller case
now again, depending on what form factor motherboard you choose. All connection ports would be standard layout for that particular form factor motherboard, even from different vendors.
Ah form Factor serves as a standard or category that could be used to ensure that there's a level of hardware compatibility between the devices of similar form factor, even though they may come from different manufacturers.
So if you choose a smaller form factor on that and choose a smaller board and get a case for that, all the case ports would line up to that smaller form factor if it's rated for that particular
Mother Border form factor. Same thing with a larger PC or larger case. If you go to a larger motherboard and it's rated differences like an A T X, all the ports would line up for that and would fit
and situate themselves to that particular case because it's rated. And again, that's the beauty of a form factor because all the devices will line up on the motherboard to the case,
even though from different manufactures and vendors.
So, according to the county, a A plus objectives you need to know in a given scenario how to install, configure motherboards, CPUs and add on cards. So you is. The technician will need to know the appropriate form factor motherboard that you will need depending on the computer need.
So with that being said, let's for jump into some motherboard history,
Um, and so we can kind of see where we are today. In the area of motherboards
back in 1981 on the plan. Our bread board was the first more the board used in a PC
and then came along in 1984. IBM came up with the 80 or the advanced technology design that the component based PC, which we know today, was born. The 84 factor proved very popular and became a standardized motherboard to fit all desktops in tower cases.
The IBM 80 form factor was the forerunner of our mother bore form factors, and that's where our lover boards came. Derived from today was theeighty.
Theeighty also had a variant known as the Baby. 80 was similar, but it was in a different with
in 1995 that began the new a TX motherboard. That's when that came out, and that's what revolutionized motherboards. And that's the standard or the when the most popper sizes. Today, Intel released the new 80 extort advanced technology extended. This new form factor featured many improvements,
including new design and layout, improving space and interchangeability of parts.
It's solved many issues faced by system builders from the original 80 design.
Later on, in 1987 Intel began manufacturing motherboards. They started their own manual motherboard manufacturing division.
Now the standard size of the A T X motherboard is 12 inches by 9.6 inches, or 305 millimeters by 245 millimeters.
Later on in 1998 the Micro a TX boards were produced.
This was board was the first backwards compatible, bored with the a T X,
Although it was nearly half the size of a standard, a TX board, its size was 9.6 inches by 9.6 inches, or 244 millimeters by 204 millimeters.
Now, later on in 2001 accompanied by name of Via Technologies introduced the I T X family of motherboards. Information technology extended is what I t. X stood for. The many I T. X was built for small cases, yet managed to pack out all the features of a regular 80 X, but again
had less expansion ports and usually just one.
And but the performance was strong as an a T X for micro a TX. The size rating on that board was only 6.7 inches by 6.7 inches, or 17 centimeters, by 17 centimeters. so in the drive of technology to go smaller and smaller while keeping the same power. That's what this was born out off.
And this for particular form factor is used in a lot of different unique situations
where it may be something smaller than a desktop format. Maybe something small, really small, like a set top box or something along those lines.
So let's look at all these motherboards individually again. The 80 x the advanced technology extended was released in 1995 and at that time it had the integrated IREPORTS. What had not been seen before integrated PS two miles connectors. But now it's USB, of course, and also
reduced drive bay interference and, um,
reduced expansion card interference. And this helped because the original 80 form factor had a problem overlapping and interfered with the drive. Bay extensions or expansion cards are adding expansion cards had a better power supply. Became would also supported 3.3 vote power support
and originally came with a 20 pan power supply connector. Later on, a 24 p. M. Power supply connector was introduced
again. This is the most comets and largest motherboard in production again. 12 inches by 9.6 inches. 305 millimeters by 244 millimeters. So the A T X is the standard as faras desktop PCs. Of course, there are many different variations of motherboards outside of
the ones that were going to speak here today, but we're only focusing on the ones that the cop aids here.
I expect you to know
Micro A T X, introduced in 1998. It was a smaller motherboard size, backward compatibility and at the same mounting holes in power supply as the 80 X limited expansion slots. Again, the size here was only 9.6 by 9.6 inches,
making it unique for very devices
or a situation that you needed a smaller desktop or smaller form factor. Sometimes you may not want a Tower PC that we were traditionally no. That's where you would use a smaller form factor and the mic micro. A T X would be a great fit for that
Ah, very popular motherboard for smaller desktop PCs and other small form factor uses.
And finally, the I t X, the M I t X from the i T X family information technology extended. Introduced in 2001 they were often used in low cost, small setups found in cars,
network devices, set top boxes and other small computers
designed for famous cooling with low power consumption. Architecture that made him very used for like for home PC theaters, where the fan noise did not distract from the cinema experience. And the size for this unit was 6.75 by six points on five inches or 17 centimeters by 17 centimeters.
And here we can see all three lined up together.
First, we have the standard A TX at 12 inches by 9.6 inches, and you can see how the small motherboards came into play and got smaller and smaller.
The micro a TX 9.6 inches by 9.6 inches. And yet we even went smaller to the many I T. X as 6.7 inches by 6.7 inches. And again, all of them have unique features, depending on your system that you're building.
If you're using a or building a tower PC or a regular standard desktop PC, you don't want to go to a standard A TX
if you're looking for a smaller form factor PC like a table top PC or something along those lines, you would use the micro A T X, and finally, the many I t X were especially unique situations. Set top boxes. Small, ultra small, developed a device form factors. Unique situations where you need it.
Less space but still the same power that 6.7 inches by 6.7 inches.
OK, so let's review what we went over today. In our lesson, we talked about the form factor and got an understanding of what the form factor or what that's Herm really means.
Then we had a little bit of motherboard history to explain how we are arrived at where we are today.
We talked about Theeighty ex mother board, which is the most common and standard motherboard that we used today. Then we talked about the micro A T X, and how that was got even smaller and smaller. Yet we talked about the many I t. X and again. There are many different variations of motherboards on the market today,
but four calm Tia purposes were talking about the a t X,
my critics, and in many I t X So that's all for less than today. I hope you learned a lot and I will see you in the next lesson.
