which microprocessor is used of the dozens currently available determines not only the processing power of the computer but also what software language it understands(and thus what program it can run)
opropcessors : An adjunct to the mircoprocessor,the coprocessor permits a computer to carry out certain operations much faster.A coprosessor can make a computer run five to ten times faster in some operations.
Memory : Required by the by the microprocessor to carry out its calculations,the amount and architecture of the memory of a system determines how it can be programmed and,to some extent,the level of complexity of the problems that it can work upon.
Bios ; The basic input/output system or BIOS of a computer is a set of permanently recorded programs routines that give the system its fundamental opernational characteristics.It determines what the computer can do without loading a program from disk and how the computer reacts to specific instructions that are part of those disk based programs.
Expansion Slots : They act as portals that allow new signals to enter the computer and directly react with its circuitry expansion slots allow new features and enhancements to be added to the system as well as permitting the quick and easy alteration of certain computer prerequisites,such as video adapters.
Support Circuitry : A Microprocessor,although the essence of a computer,is not a computer in itself(if it were it would be called a computer). It requires a number aof additional circuits to bring it to life:clocks,
controllers,and signal converters.Each of these support circuits has its own way of reaching to programs,and thus helps determine how the computer works..
