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.
Long term scheduler calculates which processes are admitted to the machine for processing. It accepts the degree of multiprogramming. Once accepted, a job converts a process.
Explain the various page replacement strategies. Page replacement-basic scheme with diagram Optimal page replacement LRU page replacement FIFO page replacement LRU
NEXT FIT ALGORITHM Here scanning starts from the first fit position and then it finds the next position which is large sufficient to hold the process. Thus the name next fit.
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
Questiion 1 Use Priority Scheduling Algorithm to schedule the following processes Process Burst Time Priority/Time P1
why we say " OS is a resource allocator" and “OS is a control program"?
SSTF stands for Abbreviation of SSTF is Shortest-Seek-time-first scheduling
Explain the Proper Distribution of Functionality and Code It is important to note that the bandwidth of the server operating system and server processor availability is fixed.
my Operating System is windows trust but when the windows start say its windows xp. help pleaes
The procedure for handling the page fault is as follows 1. We check the internal table to verify whether the reference was valid or invalid. 2. If the reference was invalid,
