In computing, a collection of data or a
program stored in a computer's external
memory, for example on disc. It might include
anything from information on a firm's
employees to a program for an adventure game.
Serial files hold information as a sequence
of characters, so that, to read any
particular item of data, the program must
read all those that precede it. Random access
files allow the required data to be reached
directly. Files usually consist of a set of
records, each having a number of fields for
specific items of data. For example, the file
for a class of schoolchildren might have five
fields containing each child's family name
(1), first name (2), house name or number
(3), street name (4), and town (5). To find
out which children live in the same street
one would look in field 4.
