Explain with the help of examples FIFO algorithms?
FIFO policy: This policy easy removes pages in the order they arrived into the main memory. By using this policy we easily remove a page based upon the time of its arrival into the memory.
For illustration if we contain the reference string: 1, 2, 3, 4, 1, 2, 5, 1, 2, 3, 4, 5 and 3 frames (i.e. 3 pages can be into memory at a time per process) after that we have 9 page faults as demonstrated
If frames are raised say to 4 then no. of page faults also raises, to 10 in this case.
Indirect addressing mode - assembly language: The Indirect addressing mode and the address field of the instruction refers to the address of a word in memory, which in turn co
What is virtual memory? Virtual memory is a technique that permits the execution of processes that may not be completely in memory. It is the separation of user logical memory
