Explanation Of the Computer Core Motherboard


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 is where the CPU or central processing unit is placed there's the memory slots and this is where the primary memory.

What Is  Motherboard?

 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 m2 slot and this is a newer slot for attaching an MDOT to solid-state drive and also on modern motherboards you also find the PCH or platform controller hub and this hub is the latest chipset architecture .

  • SSD
  • Hard Drive
  • Bridge
  • CPU

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 South Bridge chip and these chips would have different functions now the North Bridge which was located on a northern or upper portion of the motherboard acted like a middleman between the CPU PCI Express bus and memory.

South Bridge 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the CPU to communicate with these lower interfaces a had to go through the Southbridge but now this architecture has been replaced by the platform controller hub chip in the PCH architecture the functions .

 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 .

  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 .

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 rj45 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 80 X 80 X 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 .

What Is ATX Motherboard?

ATX motherboard is twelve by nine point six inches now prior to the ATX was the eighty form factor eighty stands for advanced technology and this was used in the 1980s and was developed by IBM eighteen motherboards R twelve by thirteen point eight 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 nine point six inches by nine point six 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 .
