Multitasking
| Multitasking | Multithreading | |
|---|---|---|
| 1. | Multiple task(process) processed in computer. | Single task(process) has multiple sub tasks(threads). |
| 2. | A program in running state called process(task). | During exicution, process(task) divides into subprocess(subtask) called thread |
| 3. | Each task is a heavy-weight process. | Each thread is light-weight process. |
| 4. | Each task has own memory location. | All threads share common memory space. |
| 5. | Multitasking used for utilization of CPU. | Multithreading for maximum CPU utilization. When task exicutes then sub tasks like input/output operations, read from file etc. During input output operations CPU becomes idle SO multithreading helps to reduce idle time of CPU and CPU utilization optimally. |
| 6. | Multiple task like running antivirus, printing document, listening music, copying data etc. | Multiple thread in single task like taking input stream, processing data, drawing graphics on screen etc. |
