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.

MEMORY MANAGEMENT USING BIT MAPS In this memory is separated into different allocation units each of some particular size(a few bites).consider every space of size 4k. A
Q. Several CPU-scheduling algorithms are parameterized for instance the RR algorithm requires a parameter to indicate the time slice. Multilevel response queues require parameters
Enhanced Second chance algorithm In this a modify bit is as well used. Now if the ordered pair of reference and modify is (0,0) neither recently used nor modified - the best

When a program issues a memory load or store operation, the virtual addresses (VAs) used in those operations have to be translated into "real" physical memory addresses (PAs). This
