Mention briefly the advantages of memory segmentation in 8086?



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.

Answer 2

Answer:

•    It provides a powerful memory management mechanism.

•    Data related or stack related operations can be performed in different segments.

•    Code related operation can be done in separate code segments.
•    It allows processes to easily share data.
•    It allows to extend the addressability of the processor, i.e. segmentation allows the use of 16-bit registers to give an addressing capability of 1 Megabyte. Without segmentation, it would require 20-bit registers.
•    It is possible to enhance the memory size of code data or stack segments beyond 64 KB by allotting more than one segment for each area.
