This is the third part of the operating system interview series.
In this session, we will look at the following:
1. Interprocess communication ( IPC )
2. Introduction to threads
3. Difference between threads and process
4. Multiprocessing vs multithreading
5. Multithreading challenges

I will also be showing real examples of these on my linux based operating system.
