Operating System Fundamental

An operating system is a program that acts as an intermediary between a user of 

a computer and  the computer hardware. The purpose of an operating system  is 

to provide an environment in which a user can execute program. 

An  operating  system  is  an  important  part  of  almost  every  computer  system. A 

computer system can be divided roughly into four components: the hardware, the 

operating system, the applications programs, and the users) 

The hardware ñ the central processing   unit (CPU), the memory, and the input / 

output  (I/O) devices  - provides  the basic computing  resources. The applications 

programs  ñ  such  as  compilers,  database  systems,  games,  and  business 

programs  ñ  define  the  ways  in  which  these  resources  are  used  to  solve  the 

computing problems of the users.
