Question

Differentiate between process and thread?

Answer 1

There are the following differences between the process and thread.

• A Program in the execution is called the process whereas; A thread is a subset of the process
• Processes are independent whereas threads are the subset of process.
• Process have different address space in memory, while threads contain a shared address space.
• Context switching is faster between the threads as compared to processes.
• Inter-process communication is slower and expensive than inter-thread communication.
• Any change in Parent process doesn't affect the child process whereas changes in parent thread can affect the child thread.
