=> Memory segmentation is the division of a computer's primary memory into segments or sections. In a computer system using segmentation, a reference to a memory location includes a value that identifies a segment and an offset within that segment. Segments or sections are also used in object files of compiled programs when they are linked together into a program image and when the image is loaded into memory.
Some of the advantages of memory segmentation in the 8086 are as follows :
- With the help of memory segmentation a user is able to work with registers having only 16 bits.
- By memory segmentation the various portions of a program can be of more than 68kb.
- The data and the users code can be stored separately allowing for more flexibility.
- Also due to segmentation the logical address range is from 0000H to FFFFH the code can be loaded at any location in the memory.
