Process vs Thread in Operating System

In an operating system, a process is a unit of execution that has its own memory space, resources, and state. A thread, on the other hand, is a subset of a process and shares the same memory space and resources of the process it belongs to.

Key differences between a process and a thread:

1. A process is an independent entity, whereas a thread is a part of a process.
2. Processes have their own memory space, while threads share memory with other threads in the same process.
3. Switching between processes requires more overhead compared to switching between threads.
4. Processes are heavyweight, while threads are lightweight in terms of resource usage.
5. In a multi-threaded process, threads can communicate easily with each other as they share the same resources.

Understanding the differences between processes and threads is important for designing efficient and stable operating systems.
