Motherboards Explained

What is a motherboard so that’s what we’re going to talk about in this video. Now the motherboard is the main component of a computer. It’s often referred to as the main board or mobo for short it’s basically a large circuit board that fits into the computer case and it’s where all the computer components connect to so for example There’s the CPU socket the CPU socket is where the CPU or central processing unit is placed. There’s the memory slots and this is where the primary memory DIMM modules known as RAM are inserted, and there is also the bus slots or expansion slots And these are used to install various components to add more capabilities to a computer, such as a video card sound card, network card and so on, then there’s also the SATA connectors, and this is where you would attach your storage devices, such as SSDs or hard drives Motherboards we’ll have several of these connectors so you can attach multiple storage drives. And on some modern motherboards you might find the M.2 slot, and this is a newer slot for attaching an M.2 solid-state drive and Also on modern motherboards, you’ll also find the PCH or platform controller hub, and this hub is the latest chipset architecture by Intel that’s replaced the older architecture. Now on older motherboards there would be a couple of chips on the motherboard called a chipset. There would be the northbridge chip and the southbridge chip, and these chips would have different functions. Now the northbridge, which was located on a northern or upper portion of the motherboard, acted like a middleman between the CPU PCI express bus and memory. And the southbridge which was located on a southern or lower portion of the motherboard, was responsible for things like the standard PCI slots, SATA connectors, USB ports and so on. So in order for the CPU to communicate with these lower interfaces it had to go through the southbridge. But now this architecture has been replaced by the platform controller hub chip. In the PCH architecture, the functions of the northbridge have been largely integrated into the CPU. So the northbridge chip has been completely eliminated. And the functions of the southbridge are now done entirely by the platform controller hub chip. Now motherboards come with several input/output interfaces and these interfaces are largely located on the rear input/output panel of the motherboard. So for example, the most common interface on a motherboard is a USB port. USB stands for universal serial bus and motherboards will typically have Several USB ports because there are so many different peripherals that utilize the USB interface. Such as keyboards, mice, cameras, external drives, and printers. And in addition to connectivity the USB port also supplies electrical Power to that specific device. Now the majority of USB ports are mounted in the rear Input/output panel and some are located on the surface of the motherboard. Some motherboards will also have a built-in video adapter and this is known as integrated video because the video adapter and the motherboard are essentially one unit. Older motherboards will have either a DVI or VGA port while modern motherboards will have an HDMI port or a displayPort. Now integrated video adapters are not very powerful They are good for normal everyday use with light applications But when used for extensive graphic applications such as gaming they can fall short that’s why a lot of people will bypass the integrated video and add an expansion video card that has enough power to suit their needs. And some other things that would appear on a rear input/output panel is the network interface card. And this port is designed for an RJ-45 connector with an Ethernet cable to connect the computer to a network. And there’s also a sound card. And just like integrated video, if a motherboard has a built-in sound card Then this is known as integrated sound. A sound card is what processes audio through the computer speakers Now motherboards come in different shapes and sizes. And this is known as a form factor. And the most common motherboard form factor that’s used in PCs today is ATX. ATX stands for advanced technology extended. It was created in 1995 and is now the de facto standard form factor for PCs today A full-size ATX motherboard is 12 x 9.6 inches. Now prior to the ATX was the AT form factor. AT stands for advanced technology And this was used in the 1980s and was developed by IBM AT motherboards are 12 x 13.8 inches in size and they are no longer in development since the succession of the ATX Another version of the ATX motherboard is the micro ATX Micro ATX motherboards are smaller than ATX boards as its name suggests Micro ATX boards are 9.6 x 9.6 inches. So it’s a square design compared to the standard rectangular design of the ATX. These boards are cheaper than ATX boards and were designed to fit in smaller computer cases They also have fewer features and consume less power than a standard ATX board So thank you all for watching this video as an introduction to motherboards And if you want to know which motherboards that I recommend I’ll put a list in the description below of this video So please subscribe and I’ll see you in the next video

  1. Fantastic, I am always like "wow, so that was why" , when I see your videos. Thanks for sharing all this with public. Very appreciated.

  2. sir animation are amazing I like it and your way of explanation too good too good too good 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

  3. Great video! Thanks. your video is super effective help me learn fast what i have to learn, keep update videos yes..? i will support you 🙂

  4. Thank you so much ,this is a great video, it was informative. I have some questions to you.
    The first one :Are there any difference between MCH (memory controller hub) and PCH (platform contoller hub),
    2. Could you make an explanation video about VRM? (voltage regulator module and what's the meaning of phases like 4+4 or 8+3)?
    3. What is the MOSFET and PWM?
    and the last one is: How the motherboards naming works? (I mean X, B, H etc and what's the difference between them?).

    Thank you in advance and apologize for many question.

  5. i want to build a good spec and small gaming pc.. but in my country m-atx mobo price is higher than standard atx mobo.. i feel sad about it..

  6. This chanel is too good for me and for everyone who want to learn IT. Well explained and image was very useful and helpful ❤️❤️(I am Romanian)

  7. Very informative. Can you do a video about all mother board sizes like eatx or itx? As well as some other lesser know sizes

  8. Excellent Video again.. I'm glad your doing these video's assuming that most of us are not Computer experts.. Maybe you'll get into a more complicated subject, like how a CPU & GPU works, and what a layperson can do to make things better…..

  9. Thought not going to learn anything but will watch it for giggles… Then discovered the north / south bridge had been replaced. Haven't built many PCs over the last few years and have lost touch with technology.

  10. Have you made a video of "How does the storage device work?" Especially SSD. If you haven't, please make one. This channel is by far the best educational channel I've ever watched!

  11. i don't know why you still have 314k subscribers, but your videos are better than other YouTube channels.Your channel should hit 1M subscriber's.

  12. Your powerpoint skills, build through the years your time and your effort will be paid, from?
    One of the best videos on youtube for HARDWARE, I really will need this 13 years ago!
    Nice reminder!
    May God bless you and guide us to the straight path!
    Why we dont have teachers in school like this?

    "M.2 slot"

    M.2 is a form factor. It means only that the storage device that plugs into it is similar in size to a piece of chewing gum.

    There are two types of M.2 drives:

    1) SATA and 2) NVMe

    The SATA versions of M.2 drives are, in terms of performance, identical to the 2.5" form factor SATA drives. Both connect to the chipset's AHCI (Advanced Host Controller Interface).

    NVMe M.2 drives connect directly to the PCI Express bus, and (unless you purchase a lousy one) will be 4 to 7 times faster than the SATA drives.

    The SATA versions for M.2 drives are not interchangeable with the NVMe M.2 drives. They look the same, but they are not the same.

    Here is a photo of an M.2 SATA drive:×1280/products/805/2124/Crucial_M2_SATA_M550_2__86447.1425573408.jpg?c=2

    (note that it will perform exactly the same as this form factor of a SATA drive: ).

    Here is a photo of an M.2 NVMe drive:

    Note the differences in the notches, on the right-hand side of the photos. That is how you can tell the difference between a SATA M.2 drive and an NVMe M.2 drive.
    The notch on the other end is there for a screw to hold drive in place.

    So you have to know which type of M.2 drive is compatible with your motherboard.
    Or, if you are planning on purchasing a motherboard, make sure you purchase one that is a match for what you are planning.

    The SATA versions are less expensive. They are also slower (but that does not mean that they are slow).
    The SATA drives are like a new Corvette. Whereas, the NVMe drives are like Top Fuel drag racing cars.
    For most people, you might not even notice the difference in normal day-to-day use. If something takes .5 seconds or .1 seconds, will it be noticeable? If your computer will be used in a manner where storage speed must be warp speed, then go for NVMe.


  14. It is a good applaudable work, but is like learning heart surgery by watching cartoons! Most likely the patient would die if you do what you learned from it in real!

  15. Thank you! Will you be making any material for the core series available for purchase? I found the pdfs you made before really helpful.

  16. Im an electrical engineering student and this channel is really helps me a lot to understand the basics! Thank you very much for uploading these nice gems

  17. Greetings from switzerland. Thank you! You explain it way better (and more in detail) than my teachers.
    You deserve more views – great job Sir!
    Best regards, a IT trainee

  18. What software is used to create these videos? Is this done with PowerPoint or Keynote? Or are they using some high end Adobe animation software?

  19. Wonderful job 👍ur all videos r very very helpful,fantastic, easy to understand, such a fabulous job…plz making the video related to desktop support engg or basic interview level questions answer video.

  20. Thanks for this video.. You explained a lot and in a way that is easily understood.. I have always had good luck with Gigabyte motherboards and AMD CPU's.. I am slowly converting over to SSD's..

  21. Omg where did you learn to teach like that, geeze you sre a genius in not just your field but very cleaverly talented in every way as i see it, very thorough teachings of every subject you teach, keep it up cuz i know thw audience loves it.

  22. Kindly explain, how the data is distributed and processed among multiple CPU's in a 2 and 4 CPU supported server motherboard. what happens to current processing data when 1 of 2 CPU, or 1 or more of 4 CPU's fails or burns in a motherboard. i did not get proper details online. i believe that you would post a video about it. Thanks in advance. Your videos are extremely useful for learners.
