Multiprogramming:

  • Multiprogramming is the concept in which several processes or programs runs in a single Central Processing Unit (CPU).
  • The multiple processes are scheduled by running the programs in CPU. Sometimes, the computer will be blocked for a specific time to permit the processing time for other programs.
  • If the program is executed concurrently then it improves the system throughput and there will be complete utilization of system resources.

Operating System (OS):

In a computer, OS is a collection of software that enables the computer hardware to communicate with the software.

  • This helps to control the traffic in the computer and also schedules the processing time and memory for each process.
  • The basic operations such as reading the input through keyboard, displaying the output in monitor are managed by the OS.
