COMPUTERIZED FILE

SYSTEM

Computer file

Is a block of arbitrary information, or

resource for storing information, which is

available to a computer program and is

usually based on some kind of

durable storage.

Computer files can be considered as the

modern counterpart of

paper documents which traditionally are

kept in offices' and libraries' files, and this

is the source of the term.

File System

Is a means to organize data expected to be

retained after a program terminates by
