Basic Information Technology
Concept

Information technology - the use of
modern technology to aid the capture,
storage,
retrieval,
analysis,
and
communication of information.

The various methods of delivering
information are by the use of data, text,
image, and voice for personal or
organization needs.
History of Computers

sets of units to represent numbers or quantities.
 A number or a quantity can be represented by
a physical thing, whether it is:
a pebble
a transistor
an electrical relay
a mark on a bit of paper
a bead of wire
a mechanical gear wheel
a vacuum tube
