Overlay structured program:
A program consisting of overlays is referred as overlay structured program in which an overlay is a part of program which has similar load origin as some other part(s) of the program. Such type of a program contains
a. A permanently resident portion, called the root
b. A set of overlays
The overlay structure of a program is planned by identifying mutually exclusive modules- i.e. modules that do not call each other. The major idea is that such modules do not require residing simultaneously in memory. Therefore they are located in different overlays with similar load origin.

Hashed page table method A general approach for managing address spaces larger than 32 bits is to use a hashed page table with the hash values being the virtual-page number.
Assume there are only 4 page frames in the physical memory, for the following reference string: 1, 2, 3, 4, 5, 3, 4, 1, 6, 7, 8, 7, 8, 9, 7, 8, 9, 5, 4, 5, 4, 2, 8. a) What i

What are the different files attributes? File name:-it's the name of the file. It's the name with which the user identifies. Identifiers:-it's created when a file is created
Explain the various file types A common technique for executing file types is to contain the type as part of the file name. The name is split into two parts - a name and an ext
