A computer system comprises hardware and software components, aiming to offer a powerful computational tool. These systems play a crucial role across diverse domains, aiding us in numerous tasks. The prevalence of the internet has significantly bolstered the utilization of computers for information sharing and communication. Computer systems empower us to store, process, display, and transmit information. Even in a basic modern computer system, multiple programs are typically required to carry out various functions effectively.

Multiprogramming operating systems

In batch operating system, the jobs are submitted in the batch and all the resources are reserved to one job at a time. This drawback of batch operating system may be overcome by multiprogramming operating systems.

When two or more programs are in memory at the same time, sharing the processor is referred to the multiprogramming operating system. Time sharing is a special case of multiprogramming where a single CPU serves a number of users at the interactive terminals.

Multiprogramming assumes a single processor that is being shared. Multiprogramming operating system monitors the state of all active programs and system resources. This ensures that the CPU is never idle unless there are no jobs.

In a multiprogramming system, several programs are in a state of partial completion at any time. Resources allocated to a program are utilized when the program is executed.

Multiprogramming improves both system throughout and resource utilization. The job submitted to the operating system requires CPU for computation and I/O for their I/O needs.

There are three different forms of multiprogramming operating system:
*Multitasking operating system
*Multiuser operating system
*Multiprocessing operating system
