EXAMPLE FOR SEGMENTATION
Consider an instance as given in the table and we have five segments numbered from 0 through 4 the segment is stock in the physical memory as shown. The segment table has a detach entry for every segment giving the beginning address of the segment in physical memory and length of that segment.
For illustration segment 2 is 400 bytes long as well as begins at location 4300 and a reference to byte 53 of segment 2 is mapped onto location 4300+53=4353.
Q. Segmentation is alike to paging but uses variable-sized "pages". Describe two segment-replacement algorithms based on FIFO and LRU page replacement schemes. Remember that since
In a multiprogramming and time-sharing environment, several users share the system simultaneously. This situation can result in various security problems. a
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 elemen
Q. When a process creates a fresh process using the fork() operation which of the following state is shared among the parent process and the child process? 1 Stack 2 Heap
Smith, who is a civil engineer, purchased a 30-hectare block of land in Australia in 1986 and used two hectares of it as a main residence. The part that was not main residence cost
Determine the syntax of the Fork and Join Primitive Answer: Syntax of the Fork and Join Primitive is as follow: Fork Join
Define the Main reason to encrypt a file Major reason to encrypt a file is secure it for transmission.
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 conta

A- Consider a computer system that provides a virtual memory space that consists of 8 pages. The physical memory contains 4 pages where the page size is 4Kbytes. Assume that at sp
