3) Discuss a complication that concurrent processing adds to an operating system.Support your response.

4) Address the following: why use threads?

5) Given an operating system that supports a one-to-one relationship between user-level threads and kernel-level threads and allows one or more threads from a process to issue blocking system calls while other threads (within that process) continue to run.
