What is motherboard

Motherboard Definition

Motherboard is the most important component of a computer, this device works as a platform or main circuit of a computer, integrates and coordinates all the other elements. Motherboard is also called  motherboard, central board, mother board,  in English it is known as  motherboard or mainboard . For a motherboard to do its job, very basic software called BIOS is installed on it . It also usually has slots along with other circuitry that allow communication ports and peripheral devices to be connected.

Motherboard is a board that contains all the connectors that are needed to connect the other cards of the computer. A motherboard houses the connectors for the processor, RAM, Bios, serial ports, parallel ports, memory expansion, screen, keyboard, hard drive, plugs. Once the motherboard has been equipped with the aforementioned elements, it is called a “ Chipset ” or processor set.

Functions

A motherboard must basically perform the following tasks:

  • Physical connection.
  • Administration, control and distribution of electrical energy.
  • Data communication.
  • Timing.
  • timing.
  • Control and monitoring.

On most computers it is possible to add memory cards directly to the motherboard. You may also be able to upgrade to a faster PC by replacing the CPU chip. To add additional core features, you may have to replace the entire motherboard. Motherboard is sometimes abbreviated as mobo.

Components

The most important components of the motherboard are mentioned below:

  • A CPU socket, actual CPU is soldered directly onto this socket.
  • A power connector to distribute power to the CPU and other components.
  • Slots for main system memory, usually in the form of DRAM chips.
  • Interface chip between CPU, main memory and other components. On many types of motherboards this is known as the Northbridge. This chip also contains a large heat sink.
  • A second chip controls the input and output (I/O) functions. It is not connected directly to the CPU, but to the Northbridge. This I/O controller is known as the Southbridge. The Northbridge and Southbridge combined are known as the chipset.
  • Various connectors provide the physical interface between input and output devices and the motherboard. The Southbridge handles these connections.
  • Slots for one or more hard drives. The most common types of connections are Integrated Drive Electronics (IDE) and Serial Advanced Technology Attachment (SATA).
  • Read Only Memory (ROM), contain the firmware or boot instructions for the computer system. Also known as BIOS.
  • Slot for a video or graphics card. There are a number of different types of slots, including Accelerated Graphics Port (AGP) and Peripheral Component Interconnect Express (PCIe).
  • Additional slots for connecting hardware in the form of Peripheral Component Interconnect (PCI) slots.
