Explain the term Overlays.

An overlay is an element of program that has the same load origin as several other part of the program. These are used for reduce the main memory requirement of a program. If the problem arises when the size of program exceeds the memory size, so overlays are used. Structure of these programs contains a permanently resident portion, termed as the root.

A set of overlays
