Best answer 0 votes 0 votes Option B Virtual Memory is designed to extend the limited physical memory. If a computer has 32-bit address length that means "each process" has its individual $2^{32} -1$ address space (around 4GB) but as we have only limited physical memory we can't fulfill this demand of all processes so we use Virtual memory in combination with Page + segmentation File system, so that process is divided into smaller unit and as all of these units are not required at a time, only the required once can be brought in the main memory. By using this technique we can keep thousand of process in our Main Memory simultaneously. bhuv answered Sep 26, 2017 • selected Sep 26, 2017 by rishu_darkshadow bhuv comment Share Follow See 1 comment See all 1 1 comment reply Devendra Patel commented Sep 26, 2017 reply Follow Share Possible if supports virtual memory concept 0 votes 0 votes Please log in or register to add a comment.
