Operating System: Multiprogramming

• The most important operating system capability for sharing computer resources is multiprogramming.
• Multiprogramming permits multiple programs to share a computer system’s resources at any time through concurrent use of CPU.
• By concurrent use, we mean that only one program is actually using the CPU at any given moment.
• However, at the same time other programs can collect inputs and display outputs.
• Two or more programs are active at the same time, but they do not use the same computer resources simultaneously.
• With multiprogramming, a group of programs takes turns using the processor
