As can be seen from the plan of the computer system, the mother, or main
board is at the center of the PC computer system. Effectively it is a printed
circuit board containing the central processing unit (CPU) and the memory
modules (SIMM’s). It allows the CPU to interfaces with other parts of the computer via a
'BUS' system, into which sockets are fitted, for connection of various 'expansion'
boards. Also on the motherboard is the RAM memory, normally in the form of SIMM, or
DIMM modules in the modern PC computer, and cache memory in the form of
integrated circuits (chips). All these various components will be examined in more detail
in their appropriate sections.
Modern boards utilize a CPU with four PCI and three, or four, ISA expansion slots. Most
video boards now use the PCI connection. So, if you are upgrading from a 386, or 486,
motherboard that have a video board with VESA connectors, you may well have to
purchase a new video panel.
Most Pentium boards are also fitted with controllers for Floppy Drives, 4 EIDE devices
and Enhanced Parallel and Fast Serial Ports. This 'free's up' a couple of expansion slots
for other devices
