MOTHERBOARD

A motherboard (sometimes alternatively known as the mainboard, system board, planar board or logic board,[1] or colloquially, a mobo) is the main printed circuit board (PCB) found in computers and other technological systems. It holds many of the crucial electronic components of the system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard contains significant sub-systems such as the CPU.

Motherboard specifically refers to a PCB with expansion capability - the board is the "mother" of all components attached to it, which often include sound cards, video cards, network cards, hard drives or other forms of persistent storage, TV tuner cards, cards providing extra USB or Firewire slots, and a variety of other custom components. (The term mainboard is applied to devices with a single board and no additional expansions or capability - in modern terms this would include controlling boards in televisions, washing machines and other embedded systems, which are not true motherboards.)

Types of Computer Motherboards

There are different ways to classify motherboards, which are: 

Classification Based on Assembly

Integrated Processors

Video, graphics, sound... such facilities involve components. Peripheral device slots, serial parallel ports and input output ports are other physical components or parts that are involved in the working of a computer. When such components are provided for by the motherboard, i.e. they are built into the motherboard, the motherboard is called integrated. 

Non-integrated Processors

With non-integrated motherboards, electronic components and parts are fitted individually and as needed. Input output ports, connectors, RAM etc. are fixed to the motherboard using expansion slots. So you can add one or more components as needed. This allows for greater customization and freedom in designing a PC. Gamers, for example, could fix a high-end...
