Multiprogramming is an extension to batch processing where the CPU is always kept busy. Each process needs two types of system time: CPU time and IO time. In a multiprogramming environment, when a process does its I/O, The CPU can start the execution of other processes. Therefore, multiprogramming improves the efficiency of the system. Throughout the system, it increased as the CPU always had one program to execute. Multiprogramming systems provide an environment in which various systems resources are used efficiently, but they do not provide any user interaction with the computer system. There are more than one processors present in the system which can execute more than one process at the same time. This will increase the throughput of the system. Increased reliability: Due to the multiprocessing system, processing tasks can be distributed among several processors.More than one processor present in the system can execute more than one process simultaneously, which will increase the throughput of the system.Īdvantages of Multiprocessing operating system: In Multiprocessing, Parallel computing is achieved. Multiprocessing operating system is more complex and sophisticated as it takes care of multiple CPUs simultaneously.Increased throughout: As several processors increase, more work can be done in less.ĭisadvantages of Multiprocessing operating System.This increases reliability as if one processor fails, the task can be given to another processor for completion. The multitasking operating system is a logical extension of a multiprogramming system that enables multiple programs simultaneously. It allows a user to perform more than one computer task at the same time. Batch processing operating system pdf software#.
