1 Anonymous Asked: December 1, 2019In: Computer Science What is the need of segments in Registers? 1 1 Answer Voted Oldest Recent Best Answer admin Added an answer on December 1, 2019 at 10:08 pm Segments logically divide a program into logical entities of Code, Data and Stack each having a specific size of 64K. The segment register holds the upper 16 bits of the starting address of a logical group of memory, called the segment. The main advantages of using segments are: Logical division of program, thus enhancing the overall possible memory use and minimize wastage. The addresses that need to be used in programs are relocatable as they are the offsets. Thus, the segmentation supports relocatability. Although the size of address is 20 bits, yet only the maximum segment size, that is 16 bits, needs to be kept in instruction, thus reducing instruction length. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Featured image Select file Browse Save my name, email, and website in this browser for the next time I comment.
