Process vs Thread:
- The process can be referred as program in execution whereas thread is part of process.
- Process has its own address space whereas multiple threads share same address space of process. Each thread has its own stack.
- Process can have multiple threads but thread is the smallest unit which can execute concurrently with other threads.
- Process are quite heavyweight and have more overhead whereas thread is light weight and have less overhead.
- Process do not depend on each other whereas threads are not independent as they share address space.
- You do not require synchronization in case of process. Threads require synchronization to avoid unexpected scenarios.
- Processes can communicate to each other using inter-process communication only where as thread can communicate directly as thread share same address space.
- You can easily create new threads by calling thread’s start method but you need to copy resources of parent process to create a new child process.
