What is Motherboard and its types
Motherboard: A motherboard (also called mainboard, main circuit board or mobo) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system,
The motherboard is just like a "mother" in a family who connects all family members to each other and makes a family happy, likewise the motherboard connects all the devices to each other.
There are a few top motherboards manufacturers:
- ASRock.
- Asus.
- Biostar.
- EVGA Corporation.
- Gigabyte Technology.
- MSI (Micro-Star International)
- Intel.
Types of Motherboards:
Motherboards are described using a form factor called Advanced Technology eXTENDED(ATX) and this form factor is invented by INTEL company. ATX not only describes motherboard layout but also lays specifications for power supply and PC cabinets and different connectors for compatibility purposes
There are three main types of sizes in the motherboard:
1. Standard ATX: This motherboard comes in 305*244mm (length*breadth) dimensions, these dimensions can vary with different manufacturers.
