Program

  • It is a set of instructions that has been designed to complete a certain task.

  • It is a passive entity.

  • It resides in the secondary memory of the system.

  • It exists in a single place and continues to exist until it has been explicitly deleted.

  • It is considered as a static entity.

  • It doesn’t have a resource requirement.

  • It requires memory space to store instructions.

  • It doesn’t have a control block.

Process

  • It is an instance of a program that is being currently executed.

  • It is an active entity.

  • It is created when program is in execution and is being loaded into the main memory.

  • It exists for a limited amount of time.

  • It gets terminated once the task has been completed.

  • It is considered as a dynamic entity.

  • It has a high resource requirement.
