Essay on Motherboard

A motherboard is the physical arrangement in a computer that contains the computer's basic circuitry and components. On the typical motherboard, the circuitry is imprinted or affixed to the surface of a firm planar surface and usually manufactured in a single step. The most common motherboard design in desktop computers today is the AT, based on the IBM AT motherboard. A more recent motherboard specification, ATX, improves on the AT design.

There are different slots and sockets for CPUs, and it is necessary for a motherboard to have the appropriate slot or socket for the CPU (Christian, 2002). Newer sockets, those with a three digit number, are named after the number of pins they contain. Older ones are simply named in the order of their invention, usually with a single digit. A sample of sockets and associated processors:

Sockets supporting Intel CPUs

Socket 1 - 80486SX, 80486DX, 80486DX2, 80486DX4, and compatible processors from other manufacturers
Socket 2 - 80486SX, 80486DX, 80486DX2, 80486DX4, and clones
Socket 3 - 80486SX, 80486DX, 80486DX2, 80486DX4, and clones
Socket 4 - early Intel Pentium processors
Socket 5 - early Intel Pentium processors
Socket 6 - 80486DX4
Socket 7 - Intel Pentium and Pentium MMX (also some AMD and Cyrix CPUs)
Socket 8 - Intel Pentium Pro
Slot 1 - Intel Pentium II, older Pentium III, and Celeron processors (233 MHz - 1.13 GHz)
Slot 2 - Intel Xeon processors based on Pentium II/III cores
Socket 370 - Celeron processors and newer Pentium IIIs (800 MHz - 1.4 GHz)
Socket 423 - Pentium 4 and Celeron processors (based on the Willamette core)
Socket 478 - Intel Pentium 4 and Celeron processors (based on Northwood, Prescott, and Willamette cores)
Socket 479 - Intel Pentium M

Socket 603/604 - Intel Xeon processors based on the Northwood and Willamette Pentium 4 cores
