Multitasking refers to the ability of a computer system to perform multiple tasks simultaneously, switching between them quickly to give the appearance of parallel execution. This is typically achieved through time-sharing, where the CPU rapidly switches between different tasks to give the illusion of parallel processing.
Multiprogramming, on the other hand, refers to the ability of a computer system to execute multiple programs concurrently. In multiprogramming, multiple programs are loaded into memory and the CPU switches between them based on certain criteria, such as priority or time slice. This allows for better utilization of system resources and can improve overall system performance.
In summary, multitasking involves switching between multiple tasks quickly to give the appearance of parallel execution, while multiprogramming involves executing multiple programs concurrently to improve system performance.

Multitasking
- Allows multiple tasks to run concurrently on a single processor.
- Allocates CPU time to each task in a round-robin or priority-driven fashion.
- Gives the illusion of simultaneous execution, but in reality, the tasks are executed one at a time.
- Each task has its own dedicated memory space.
- Suitable for systems with limited resources or for tasks that do not require significant processing power.
Multiprogramming
- Allows multiple programs to reside in memory simultaneously and share the CPU.
- Runs multiple programs concurrently, but only one program executes at any given time.
- When one program is waiting for input or output operations, the CPU switches to another program.
- Improves CPU utilization by keeping it busy when one program is idle.
- Each program has its own dedicated memory space.
- Requires more memory resources than multitasking, as multiple programs are loaded into memory.
Key Differences
| Feature | Multitasking | Multiprogramming |
|---|---|---|
| CPU Execution | Concurrent on a single processor | Non-concurrent on a single processor |
| Memory Space | Dedicated for each task | Dedicated for each program |
| Suitable for | Resource-limited systems | Resource-rich systems |
| Illusion | Provides the illusion of simultaneous execution | No illusion of simultaneous execution |
