A typical motherboard
provides attachment points for one or more of the following: CPU,
graphics card, sound card, hard disk controller, memory (RAM), and
external peripheral devices.
A motherboard can come in many configurations to fit different
needs and budgets. At its most basic, it comes with several interfaces
for necessary components and a BIOS chip set to control setup of
the motherboard. Many computer enthusiasts favor one type of BIOS
over another and will choose a motherboard partially based on the
BIOS manufacturer. For example, many gamers prefer the Nvidia BIOS
as it is rated as one of the best for graphics applications.
An equally important feature of the motherboard is the type of
CPU it will support. Some motherboards support AMD CPUs, while others
support Intel processors. Within the manufacturer's categories,
there are different grades of CPUs. An AMD 64-bit processor requires
a different CPU socket than an AMD 32-bit processor. Thus, if purchasing
parts independently, one must decide on the CPU before choosing
the motherboard to ensure compatibility.
Another important consideration is the amount and type of RAM
the motherboard will support. It is always best to buy a board that
supports more RAM than currently needed. If new technology for RAM
chips is available, getting a board that supports the newer chips
will help future-proof the investment..
The number of PCI slots varies from motherboard to motherboard,
as do other interfaces like the number of SATA ports, differing
RAID abilities, and USB and Firewire ports. As mentioned prior,
sound and video capability might be built-in, though purists generally
prefer to disable internal video and sound and add superior third
party cards. A motherboard also comes in one of a few standard footprints
or sizes. This figures in when purchasing the system case. Along
these lines, many motherboard manufacturers recommend particular
power supplies that have been tested with the board.
Though building a computer used to be somewhat challenging, today
most motherboards are color-coded with controllers built-in, making
it very easy to build a computer from scratch. The only time consuming
aspect is investigating which hardware will best suit your needs
while fitting into your budget. Once the CPU and motherboard is
chosen, RAM is somewhat determined by the board itself. Hard drives,
an optical disk, a video card, a sound card and a floppy round out
the basics.
Most motherboard today was designed for IBM compatible computers
which holds over 96% of the computers in the market today.
