Example Of Process Management In Operating System

The operating system also has to synchronize the different processes of computer system. A process consists of set of instruction to be executed called process code. Actually this process is called as process scheduling in which operating system decide which process needs to get into the cpu for execution and how much.

Scheduling processes and threads on the cpus.

Example of process management in operating system. The pcb is a full form of process control block. It is a data structure that is maintained by the operating system for every process. There s a question which arises while discussing operating systems that involves when to call all the activities of the cpu. The operating system is responsible for the following activities in connection with process management.

Providing mechanisms for process synchronization. Every process is represented in the operating system by a process control block which is also called a task control block. The resources that a process. Even on a single user operating system like microsoft windows a user may be capable of running more than a few programs at one time like ms word processor different web browser s and an e mail messenger.

Process priority and other scheduling information which is required to schedule the process. Suspending and resuming processes. A process is also associated with some data that is to be processed. When a process runs on computer device memory and cpu of computer are utilized.

For example devices allocated to the process open files etc 8. This includes the information of page table memory limits segment table depending on memory used by the operating system. Can be ready running etc. A process state is a condition of the process at a specific instant of time.

A unique identifier assigned by the operating system 2 process state. Providing mechanisms for process communication. Creating and deleting both user and system processes. Like the program counter cpu registers must be saved and restored when a process is swapped in and out of cpu 5 accounts information.

Processor management in case of multiprogramming environment system gets multiple programs for execution and operating system has to decide which program should be send to cpu for execution and for how much time.
