What are the advantages of multiprogramming?
Multiprogramming makes effifcient use of the CPU by overlapping the demands for the CPU and its I/O devices from various users. It attempts to increase CPU utilization by always having something for the CPU to execute.
Advantages of multiprogramming operating system: i) It increases CPU utilization. ii) It decreases total read time needed to execute a job. iii) It maximizes the total job throughput of a computer. Disadvantages of multiprogramming operating system: i) It is fairly sophisticated and more complex ii) A multiprogramming operating system must keep track of all kinds of jobs it is concurrently running.
Multiprogramming is the rapid switching of the CPU between multiple processes in memory. It is done only when the currently running process requests I/O, or terminates. It was commonly used to keep the CPU busy while one or more processes are doing I/O. It is now mostly superceded by multitasking, in which processes also lose the CPU when their time quantum expires.
