Difference between Process and Thread
Process:
Process means any program is in execution. Process control block controls the operation of any process. Process control block contains the information about processes for example: Process priority, process id, process state, CPU, register etc. A process can creates other processes which are known as Child Processes. Process takes more time to terminate and it is isolated means it does not share memory with any other process.
Thread:
Thread is the segment of a process means a process can have multiple threads and these multiple threads are contained within a process. A thread have 3 states: running, ready, and blocked.
Thread takes less time to terminate as compared to process and like process threads do not isolate.
Difference between Process and Thread:
| S.NO | Process | Thread |
|---|---|---|
| 1. | Process means any program is in execution. | Thread means segment of a process. |
| 2. | Process takes more time to terminate. | Thread takes less time to terminate. |
| 3. | It takes more time for creation. | It takes less time for creation. |
| 4. | It also takes more time for context switching. | It takes less time for context switching. |
| 5. | Process is less efficient in term of communication. | Thread is more efficient in term of communication. |
| 6. | Process consume more resources. | Thread consume less resources. |
| 7. | Process is isolated. | Threads share memory. |
