Medium term scheduling is form of the swapping operation. This attaches to processes that are in a suspended or blocked state. They are swapped out of real-memory storage until t
Using pages makes it easier to manage the whole memory, avoiding excessive fragmentation and waste. As an analogy, think of Tetris, but with only square blocks: it is relatively ea
What criteria are important in choosing a file organisation?
What is internal fragmentation? Consider holes of 20k assume the process requests 18 bites. If we allocate accurately the request block, we are left with a hole of 2k. The over

What are the various file operations? The six basic file operations are Creating a file Reading a file Writing a file Repositioning within a file Tr
Define throughput? Throughput in CPU scheduling is the number of processes that are completed per unit time. For long processes, this rate might be one process per hour; for sh
Explain thread in details
For example, by initializing a semaphore to 0, threads can wait for an event to occur, and impose an ordering constraint, similar to a monitor using condition variables, but with m
