Hashed page tables
A common approach for handling address spaces larger than 32 bits is to use a hashed page table. Every entry in the hash table having a linked list of elements that hash to the similar location.
Each element consist of three fields
a) The virtual page number
b) The value of the mapped page frame
c) A pointer to the next element in the linked list.
Deadlock Avoidance It's a method to evade deadlock by careful resource scheduling. This approach to the deadlock problem foresees deadlock before it actually occurs. This a
What is operating system?
Medium term scheduling This is component of the swapping function. Usually the swapping in decision is based on the need to manage the degree of multiprogramming. At a system t
The hardware to support demand paging is as follows Page table: This table has the skill to mark an entry invalid though a valid-invalid bit or particular value of protectio
Extend task 1 so that the requests are issued by the clients instead of the server. The server now do not use the "all_requests.dat" file. Instead every client thread reads from
Basic concepts When a process is to be changed in, the pager guesses which pages will be used before the process is changed out again. Instead of swapping in a entire process,
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
What are conditions under which a deadlock situation may arise? A deadlock situation can arise if the following four conditions hold simultaneously in a system: a. Mutual ex
categorize the CPU scheduling algorithms and among them explain the non-preemptive algorithms..
