INTRODUCTION Operating system (OS) is a set of programs that acts as an interface between user and computer hardware. It also manages the internal resources of a computer like control Unit‚ arithmetic logic unit‚ memory unit‚ I/O unit etc. simply we can say that operating system (OS) is a communication channel between the user and the computer machine. It is must for any computer system because the OS is only: The one program that runs at all the times on the computer. The program that

Operating System An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. It is a program designed to run other programs on a computer. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software

System call provides the means for a user program to ask OS to perform OS tasks on the user program’s behalf. When a system callis executed‚ it is treated by H/W as a S/W interrupt. Timer protects CPU resource from getting stuck by a user program. To ensure OS maintains
