All of the components of a computer are connected to the motherboard via a single platform. It uses cables or other direct connections to connect the CPU, RAM, hard drives, optical drives, video cards, sound cards, and other ports and expansion cards. It might be viewed as the foundation of a computer.

What is Motherboard?

A motherboard is the primary printed circuit board (PCB) in general-purpose computers and other extensible systems. It is also referred to as a mainboard, main circuit board, MB, board, backplane board, base board, system board, logic board (only in Apple computers), or the mobo. The primary printed circuit board in all-purpose computers and other expanding systems is called a motherboard. It provides connectors for additional peripherals and retains and enables the communication between many of the critical electronic parts of a system, including the memory and central processing unit.

Features of Motherboard

A motherboard has the features listed below:

  • The ability of a motherboard to accommodate multiple component types varies substantially.
  • One type of CPU and a small number of memory types are supported by the motherboard.
  • To work effectively, hard drives, sound cards, and video cards must be compatible with the motherboard.
  • To function correctly with one another, motherboards, chassis, and power supply must be compatible.

Popular Manufactures

The well-known motherboard manufacturers are listed below.

  • Intel
  • ASUS
  • AOpen
  • ABIT
  • Biostar
  • Gigabyte
  • MSI

About of Motherboard

Inside the case, the motherboard is placed and firmly fastened using tiny screws that are inserted through pre-drilled holes. All of the internal components can be connected via the motherboard’s connectors. The CPU, it offers a single socket, whereas there are typically one or more slots available for the memory. Ribbon cables can be used to connect the hard drive, optical drive, and floppy drive to ports on motherboards. The motherboard has fans and a unique port for the power supply.

Video cards, sound cards, and other expansion cards can be linked to the motherboard using a peripheral card slot that is located in front of the motherboard.

The monitor, printer, mouse, keyboard, speaker, and network cables can all be connected to the motherboard’s various ports on the left. Additionally, motherboards have USB ports that can be used to plug in and plug out suitable devices. Pen drives, digital cameras, etc. are a few examples.

History of Motherboard

The IBM Personal Computer used the first motherboard, which was originally referred to as a “planar.” IBM released the AT, or Full AT, motherboard form factor in August 1984. In 1985, IBM unveiled the Baby AT motherboard form factor. Western Digital created the LPX motherboard form factor in 1987.

FAQ - Frequently Asked Questions

Ans. The first motherboard used in a computer was an IBM “Planar Breadboard in 1981. IBM engineer Patty McHugh was the creator of this technique. The model was simple with oddly arranged chips, housing RAM and CPU with supplier parts and cassette/keyboard tapes. This was the first time a computer had a motherboard.

Ans. It is the primary circuit board of the computer and can be increased by adding more circuit boards to it, hence it is called the motherboard.

Ans. The motherboard serves as the backbone of the computer, connecting all of its parts and enabling communication between them. None of the components of the computer, including the hard disc, GPU, and CPU, could interact without it. For a computer to function properly, the motherboard must be fully functional.

Ans. From largest to smallest, motherboards are available in three different sizes: ATX, Micro-ATX, and Mini-ITX (Yes, Mini is smaller than Micro). With the micro or mini boards, you can use a smaller chassis, but you’ll have to make do with fewer PCIe slots, RAM slots, and other interfaces.

Ans. It is also referred to as a mainboard, main circuit board, MB, mboard, backplane board, base board, system board, logic board (only in Apple computers), or the mobo.
