memory contains 3 holes of 10 mb each. a sequence of 14 requests for 1 mb each is to be processed. (a) for each of the four memory allocation strategies, determine the sizes of the remaining holes after all 14 requests have been satisfied:
a. first fit
b. next fit
c. best fit
d. worst it

Respuesta :

Option A is correct. The following are four typical memory management strategies used by operating systems.

The simplest allocation strategy utilized by MS-DOS is a single contiguous allocation. A process has access to all memory (apart from that that is reserved for the OS).

Memory is divided into various partitions or blocks during partitioned allocation. The allocation of each process depends on the requirement.

Paged memory management: In a virtual memory environment, memory is partitioned into fixed-sized units called page frames. Memory is separated into various segments (a segment is a logical grouping of the process' data or code). This is known as segmented memory management. Allotted memory does not need to be contiguous under this management. Segmentation with paging is used by the majority of operating systems, including Windows and Linux. A process is broken down into segments, and each segment has a page.
