A computer system can roughly be divided into three components:
·The hardware (memory, CPU, arithmetic-logic unit, various bulk storage, I/O, peripheral devices…)
·System software (operating system, compilers, editors, loaders, utilities...)
·Application software (database systems, business programs...)
A computer system can be described or shown in the following Figure.
Fig. 1 Conceptual view of a computer system
The central processing unit (CPU) is located on chips inside the system unit. The CPU is the brain of the computer. This is the place where the computer interprets and processes information.
The operating system is the first component of the systems programs that interests us here. Systems programs are programs written for direct execution on computer hardware in order to make the power of the computer fully and efficiently accessible to applications programmers and other computer users.
An application software (also called end-user program) is any program designed to perform a specific function directly for the user or, in some cases, for another application program. Examples of application software include word processors; database programs; Web browsers; development tools; drawing, paint, and image editing programs; and communication programs.
