Mainboard

The mainboard or motherboard is the main part of your computer These vary in price depending on quality and features from circa £20 to £300.

A typical computer has its microprocessor, main memory,sound, graphics controller and other essential components intregrated into the motherboard.

An important component of a motherboard is the microprocessor's supporting chipset, which provides the supporting interfaces between the CPU and the various components. This chipset determines, to an extent, the features and capabilities of the motherboard.

Modern motherboards include, at a minimum:

• sockets in which one or more microprocessors may be installed
• slots into which the system's main memory is to be installed (typically in the form of DIMM modules containing DRAM chips). The number of sockets varies from 2 to 6 on a typical mainboard. Server mainboards tend to have 6 to 8 sockets. The specification and size of the socket will determine which type of memory can be used. See Memory page for the different types available.
• a chipset which forms an interface between the processors, main memory, and peripheral buses
• non-volatile memory chips (usually Flash ROM in modern motherboards) containing the system's firmware or BIOS. see rom on memory types page.
• a clock generator which produces the system clock signal to synchronize the various components
• slots for expansion cards (these interface to the system via the buses supported by the chipset). Common types of sockets are isa(not used now), pci, agp(older graphics slot) and pci-x (v1 and 2).
• power connectors, which receive electrical power from the computer power supply and distribute it to the CPU, chipset, main memory, and expansion cards.

Mainboards also have a set of connectors for interfacing to keyboards, printers and monitors etc.

There used to be various connections for different devices such as printers etc. These included scsi, parallel and serial. the majority of peripherals now use a universal serial bus connector or usb. There are different versions of usb connector which offer different speeds( currently up to version 2). All usb connectors are backwards compatible.

	Chorley's leading computer shop for Business and home computer repair. Service and Repair of PC's and Apple Mac . When we were looking for premises for 1 Stop Tech shop we had a number of considerations. We wanted to be located in a strategic area at the centre of the motorway network that allowed PJR Micro Ltd to service our business and domestic customers easily and cost effectively. We therefore chose Chorley as this location. As we have continued expanding we quickly realised that our Chorley shop was to small for our purposes. We therefore started looking for new larger premises. There was nothing suitable within the immediate area so we expanded our search further afield, and located a building in Whelley, Wigan which was ideally suited for our purposes which we moved to in 2009. As our business is now going more and more data based we need a premises with fast backbone connection and as the fastest speeds we can obtain at Wigan is 3mb we have amalgamated all our business under one roof at our business service center at Coppull Where we have a 15mb and a 11mb backbone connection. Our Business customers range in areas from Liverpool to Wilmslow and Kendal to York and we have domestic customers all over Lancashire and Greater Manchester. Our new computer shop and premises have extensive offroad parking so short distance to carry sickly pc's.
