MULTIPROGRAMMING Meaning and
Definition
-
Multiprogramming refers to a computer operating system technique or strategy where multiple programs or tasks can be simultaneously executed on a single computer system. It allows for the efficient utilization of the CPU (central processing unit) by having several programs loaded into memory at the same time, with the CPU switching back and forth between them, known as context switching.
In a multiprogramming environment, each program is allocated a specific amount of CPU time, and the operating system dynamically assigns the CPU to different programs based on their priority and availability. This switching occurs so quickly that it gives the illusion of simultaneous execution to the users.
One of the key advantages of multiprogramming is the prevention of idle time for the CPU, as when one program is waiting for input/output (I/O) operations, the CPU can be utilized by executing another program. This significantly improves the overall efficiency and throughput of the system.
Furthermore, multiprogramming allows for better time-sharing capabilities as multiple users can interact with the computer system simultaneously, as each user's actions are given time slices for execution.
However, it is important to note that in a multiprogramming environment, each program is allocated a portion of the CPU time, which may result in decreased individual program performance if multiple resource-intensive programs are running concurrently. The effective management of memory, input/output devices, and scheduling algorithms are crucial for the smooth execution of multiprogramming systems.

Etymology of MULTIPROGRAMMING
The word "multiprogramming" is derived from two components: "multi-" and "programming".
1. "Multi-" is a prefix meaning "many" or "multiple", indicating the presence of more than one. It comes from the Latin word "multus", meaning "much" or "many".
2. "Programming" refers to the process of creating a sequence of instructions for a computer to perform specific tasks. It originated from the term "program", which initially referred to a schedule or plan and later evolved to denote coded instructions for computers.
Combining these components, "multiprogramming" literally means "many programming" or "multiple programming". It represents the ability of a computer system to execute multiple programs simultaneously by rapidly switching between them.
