Data
Dank is
a Computer's Speciality
The computer's splendid memory makes
it
easy
to
com¬
pile a list with a number of items. The sequence of items
as
data,
for example,
name,
age, date of birth, present address
and permanent address, is brought into memory. This is called
a data bank.
This data bank makes
it
simple
to
retrieve and sort
out
items depending
on the type of program.
Retrieving is made
for all the data related
to
any required items assigned. For
example, a blood type is assigned to retrieve all people
of
the
same blood type, and this
is
called
"retrieving by
blood type".
In
addition,
with
an
eye
to
a certain
item,
names are
arranged
in
ABC
order,
for example, or
ages
are
arranged in the order
of
the young
to
the old. This is called "sorting".
