BENEFITS OF THREADS OVER PROCESS
If implemented correctly after those threads have some advantages of (multi) processes, they take:
1. Less time to create a new thread than a process, for the reason that the newly created thread uses the current process address space.
2. Less time to finish a thread than a process.
3. Less time to switch among two threads within the same process, partly for the reason that the newly created thread uses the current process address space.
4. Less communication expenses communicating between the threads of one process is easy because the threads share everything address space in particular. Consequently, data produced by one thread is right away available to all the other threads.
We are faced with three major components of the page-fault service time. 1. Service the page-fault interrupts. 2. Read in the page. 3. Restart the processes.
Synchronization serves two purposes: 1) to ensure safety for updates on shared data (e.g. to avoid races conditions), and 2) to coordinate and order actions taken by threads (e.g.
