Multitasking refers to the ability of a system to run multiple tasks concurrently, allowing users to switch between tasks quickly. This can be seen in modern operating systems where users can have multiple applications open at the same time and switch between them seamlessly.
Multiprogramming, on the other hand, refers to the ability of a system to run multiple programs concurrently, but not necessarily at the same time. In multiprogramming, the system switches between running programs in order to maximize CPU utilization and efficiency.
In summary, multitasking allows users to switch between tasks quickly, while multiprogramming allows the system to run multiple programs concurrently to maximize efficiency.

Multitasking
- Involves a single processor that executes multiple tasks or processes concurrently.
- Each task is allocated a time slot for execution.
- The processor switches between tasks based on the time slots or priorities assigned to them.
- Only one task has actual control of the CPU at any given time.
- The operating system manages the scheduling and time allocation for tasks.
Multiprogramming
- Involves a single processor that executes multiple programs concurrently.
- The processor keeps several programs in memory at the same time.
- When one program is waiting for input or output operations, the processor switches to another program that is ready to run.
- This allows the processor to utilize time that would otherwise be wasted while waiting for I/O operations.
- Multiple programs can be in execution concurrently, but only one has control of the CPU.
Key Differences
| Feature | Multitasking | Multiprogramming |
|---|---|---|
| Concurrency | Multiple tasks executed concurrently | Multiple programs executed concurrently |
| Processor | Single processor | Single processor |
| CPU Control | Only one task has CPU control at a time | Multiple programs share CPU control |
| Purpose | Improve efficiency by overlapping tasks | Utilize processor time efficiently during I/O operations |
| Resource Sharing | Tasks share the same resources (e.g., memory) | Programs share the same resources (e.g., memory) |
| Scheduling | Time-slicing or priority-based | Memory management and I/O scheduling |
