Question

explain the concept of segmented memory. What are its advantages?

Answer 1

Segmented memory is a system of addressing computer memory, which may be physical or virtual and may be operating in real or protected mode.

The segmented memory system was used to expand the 64KB limit on first-generation flat address space. Computers made prior to segmented memory used a flat addressing system based on a four-digit hexadecimal code. With hexadecimal, the highest 4-digit number you can create is FFFF (or 65535), which equals 64KB.
