Slightly less than the number of processor in the system.
multiprogramming
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 complexii) A multiprogramming operating system must keep track of all kinds of jobs it is concurrently running.
THE multiprogramming system was created in 1968.
timesharing is logical extention of multiprogramming.
is it possible to do multiprogramming with only one partition
Multiprogramming is collecting several jobs in a job pool and the OS selects the job from the pool so that the CPU has one job to execute , in case of any IO request for the job in execution the CPU switches to another job here switching is less compared to multitasking.So a computer system which allows such type of switching in between jobs is called a multiprogramming system. Please make note that multitasking is done by user but multiprogramming is done by operating system only.
What determines the theoretical throughput of a bus
Multiprogramming increases CPU utilization by organizing jobs so that the CPU always has a job to execute.
The principal disadvantge of too much multiprogramming is the overhead of excesssive context-switching. If the context-switch rate is too high, the overhead can actually overwhelm the benefit of multiprogramming.
