OPERATING SYSTEM PROPERTIES ???-\ EXPLAIN MULTIPROGRAMMING????
When two or more programs are residing in memory at the same time, then sharing the processor is referred to the multiprogramming. Multiprogramming assumes a single shared processor. Multiprogramming increases CPU utilization by organizing jobs so that the CPU always has one to execute.
Operating system does the following activities related to multiprogramming.
#The operating system keeps several jobs in memory at a time.
#This set of jobs is a subset of the jobs kept in the job pool.
#The operating system picks and begins to execute one of the job in the memory.
#Multiprogramming operating system monitors the state of all active programs and system resources using memory management programs to ensures that the CPU is never idle unless there are no jobs
