Hii friends...
I have read this in a book...juz wasnt able to elaborate the meaning...please can u help??

At a top level,a computer consists of processor,memory and I/O Components with one or more modules of each type.These components are interconnected in some fashion to achieve the main function of the computer which is to execute programs.Thus there are 4 main structural elements:
Processor:Controls the operation of the computer and performs its data processing functions.When there is only one processor,it is often referred to as CPU.
Main Memory:Stores data and programs.This memory is typically volatile i.e when the computer is shut down,the contents of the memory are lost.In contrast,the contents of disk memory are retained even when the computer system is shut down.
I/O Module:Moves data between computer and its external environment.The external environment consists of a variety of devices including secondary memory devices ,communications equipment and terminals.
System Bus:Provides for communication among processors,main memory and I/O Modules.

Please help!!!
Thnx!
