Additional Reference bits algorithm
Here we keep an 8-bit byte for every page in memory. At standard intervals the reference bit is shifted by the OS. If a shift register contains 00000000 then the page hasn't been used for the last 8 time periods. A page with a history 11000000 is more recently used than 01000000. The no of bits are able to be varied accordingly to the needs of the OS.

Two Level Directory This kind of structure overcomes the problems of assigning unique names to the files. Thus there need not be any confusion among users. In this kind of s
What are the benefits of thread pools:- The benefits of thread pools are 1. It is usually faster to service a request with an existing thread than waiting to make a thread.
Can a direct access file be read sequentially? Explain. Yes. Keep a counter, cp, initially set to 0. After reading record cp, increment cp.
Question 1 What is a file? Write down the operations on files Question 2 What do you mean virtual machine? Write down the application of virtual machine Question 3 What
What is the different between basic synchronization and high level synchronization
Now, let us discuss two related algorithms for deciding which pages to evict. The clock algorithm is one of the most popular choices. It works by keeping frames in a circular struc
Virtual addresses are made up of two parts: the ?rst part is the page number, and the second part is an offset inside that page. Suppose our pages are 4kb (4096 = 212 bytes) long,
Briefly discuss on real-time scheduling? It is divided into two types. Hard real-time systems are needed to complete a critical task within a guaranteed amount of time. T
In this project, you will implement the Chandy and Misra's (CM) algorithm using POSIX Threads (Pthreads). The algorithm is a distributed algorithm to solve a generalized dining
