A Computer Motherboard is commonly known as Main board or MB or System board or logic board is designed on PCB (Printed Circuit Board).That holds or connects all components and parts together on a single sheet. The Computer Motherboard holds all the circuitry to connect the various components of a computer system. Therefore it is also called as backbone of Personal computer system.
The Main board or Motherboard is the main, cruical and important part of the computer system. It holds many important components such as Computer memory slots,cpu,sata IDE slots, expansions slots(PCI,AGP etc),capacitor’s, resistor’s ,BIOS chip etc The Computer main board is made up of thin sheet of non conductive material from plastic .The traces which are present on the motherboard is made up of copper/aluminum foil.
There are many companies which manufacture excellent quality of logic boards these day's such as Intel, Asus, Gigabyte, Msi, Asrock, Sapphire technology, Biostar etc

Components and Parts Used in Computer Motherboard
There are various component embedded in MB/PCB(Printed Circuit Board).You should know the basic computer functionality and uses of the various component attached to main board to use it and installed in Computer case.
Today Computer Motherboards comes in number of variety but the basic functionality and uses are pretty much the same? You must be familiar with the use and aware of the basic architecture of PC and Laptop motherboard design
As it is difficult to understand each and every part of MB still you should be aware of some common and important component & parts attached to it.

Complete Description of Computer Motherboard
The desktop or PC motherboard is mounted inside the computer case with the help of small screws which are used to tighten the system board into the computer case.The computer case possess some pre-drilled holes so that the screws can be easily fit into it.
System or Main board consist of a single CPU socket which is pre-soldered into it. There are various types of CPU socket which are used to determine the computer motherboard and the CPU which is compatible with it.
You can determine which processor is compatible or suited to the motherboard as there is a number printed on the CPU socket which determines which CPU to be installed on it.
There are memory slots commonly called as DIMM or SIMM which allow users to install memory (RAM) into it. Number of memory slots depends entirely upon the manufacturer of motherboard.

Expansion slots are used in motherboard so that you can install additional video cards, sound cards, and graphic cards into it. These expansion slots are pre-install.
Some of the expansion slots are :: PCI,AGP,ISA etc
Front panel connectors on motherboards has a Power switch, Reset, Power led, HDD led connectors which are connected by wires.
Jumpers are used for specific purposes such as CMOS clear jumper is used to reset bios password.
On the left side of the motherboard, there are number of ports which are used to connect to other peripherals of computer system such as monitors, USB drives, printers, keyboard, mouse,LAN , modem etc
There is a small coin-shaped cell commonly called as CMOS battery which is inserted into a battery connector present in the motherboard.
SATA and IDE slots are available to connect to other devices such as hard drives and DVD-RW with the help of cables. 24 pins power connector is available to connect power supply(SMPS) and additional 4 pin p4 power connector is also available.
