In the world of computer science both process and thread are counted as important terms. Process is the program under action whereas a thread is the smallest segment of instructions that can be handled independently by a scheduler. Let’s analyze the difference between process and thread.
What Is Process?
When a program is under execution, then it is known as a process. Basically, a process allows you to execute all the relevant tasks in a program. In this, the operating system helps you to design, plan, schedule, and terminate the processes used by the CPU.
What Is thread?
In the world of computer science, a thread is the smallest segment of instructions that can be handled independently by a scheduler.
Difference between Process and Thread
| S.No | Process | Thread |
| 1. | When a program is under execution, then it is known as a process. | A segment of a process is known as thread. |
| 2. | It consumes maximum time to stop. | It consumes minimum time to stop. |
| 3. | It needs more time for work and conception. | It needs less time for work and conception. |
| 4. | Context switching takes maximum time here. | Here, context switching takes minimum time. |
| 5. | It is not that effective in terms of communication. | It is effective in terms of communication. |
| 6. | It takes more resources. | It takes less resources. |
| 7. | It is a heavy weight process. | It is a light weight process. |
| 8. | If one process is obstructed then it will not affect the operation of another process. | If one thread is obstructed then it will affect the execution of another process. |
