    Give some important differences between threads and processes.
    When should I use thread and when should I use processes?
    You are given a single processor. Will it be still beneficial if I use threads to parallelize my work? Explain with reasons. If yes, give me a case.

Not necessarily, because a single processor any how will process only single thread at a given point of time, so in that case we can use a single process only to complete our work

But in case of context switch, Processes will present more overhead than threads, even on a uniprocessor

different processes occupy different memory locations, whereas different threads of the same process share the same code space.

So it will save a lot of time by using the same cache content, instead of fetching the code everytime the process switches(which will be the case if threads are not used)
