Explain about interprocess communication
The cooperating processes communicate with each other via an interprocess communication facility. IPC gives a mechanism to permit processes to communicate and to synchronize their actions without sharing the similar address space.
In a multiprogramming and time-sharing environment, several users share the system simultaneously. This situation can result in various security problems. a
Consider the following C program where M, N, K are predefined constants. Assume int is 4 bytes. Suppose this program is run on a machine with 4KB page size and 32 TLB entries. Init
The different paging techniques are 1. Multilevel paging or hierarchical paging method: In definite cases the page table may consist up to 1 million entries. This would be
what are the objective of operating system assignment
Suppose a logical address space is 1KB, and the page-size is 16 bytes. Assume no page is in the main memory for this process initially and the pure demand paging is used. Current f
VARIABLE PARTITIONING We can differ the partitions and change the location according to the size of the process. 50k 40k
Q. Several CPU-scheduling algorithms are parameterized for instance the RR algorithm requires a parameter to indicate the time slice. Multilevel response queues require parameters
In a multiprogramming and time sharing environment several users share the system simultaneously .what are two such problems?
How can deadlocks be represented? Deadlocks are able to be described in terms of a directed graph called as a system resource-allocation graph. This graph contains of the foll
