Explain segmentation hardware?
We define an completion to map two-dimensional user-defined addresses into one-dimensional physical addresses. This mapping is affected by means of segment table. Every entry in the segment table has a segment base and a segment limit. The segment base holds the starting address where the segment resides in memory, where the segment limit specifies the length of the segment.
A logical address consists of two parts that are a segment number's, and an offset into that segment d. The segment number is utilized as an index to the table. The offset d of the logical address should be between 0 and the segment limit. The segment table is fundamentally an array of base-limit register pairs.

Q. Consider the two-dimensional array A: int A[][] = new int[100][100]; Whereas A [0][0] is at location 200 in a paged memory system with pages of size 200. A little process
What are the various process scheduling concepts? a) Scheduling queues with diagram b) Queuing diagram c) Schedulers d) Context switch with diagram
explain simple segmentation
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
What is page fault and what are the steps taken by the OS to remove page fault? A page fault is caused while a page that hasn't been brought into memory is being addressed. The
What is a reference string? An algorithm is evaluated by running it on a particular string of memory references and computing the number of page faults. The string of memory re
What is the purpose of system programs? System programs can be thought of as bundles of useful system calls. They give basic functionality to users and so users do not require
1. Suggest some mechanism(s) to lower the dispatch latency while scheduling for a real-time system. Also, discuss any trade-off or consequent constraint associated with it, if a
What is the use of multiprogramming on individual processors ? In the usual multiprocessor, which is dealing with independent or coarse-grained synchronization granularity, it i
