3. We can only define Information Technology as “Whatever technology we use to get information is called
information technology".
Sometimes, the term IT is applied to computers and computer-based systems. But the root word for technology
is "the means" for achieving goals.
For example:
- when using a matchbook it is a means of creating fire. Finally is the fire itself.
- Bicycles are a means of transportation. The purpose of riding a bicycle is to reach the destination, and
maybe also to get the training needed.
As a result, when we talk about the use of technology, we must always remember that it is a means, Technology
is the application of modern communication and computing technology for the creation, management , and
use of knowledge.
Information Technology means the use of hardware, software, services, and supporting infrastructure to
manage and deliver information using voice, data and video.

conversion, analyzing, calculating, information as data.
3. Generating :IT will produce or organize information into useful forms. For example graphs, tables, calculations,
and so forth.

7. E. Components of Information Technology
In information technology activities there are 5 main components in it, namely:
1. Computer: A computer is an electronic system that can be programmed to receive data processing, store it for
future use, and display data and information.
2. Hardware: The physical part of the computer such as a system unit etc.
3. Software: The logical part of a computer that tells the computer what to do.
4. Network Communication: this is the interconnection of various locations through media that allows people to
send and receive information. Communication networks allow people and businesses to work together. This
includes hardware, programs, and information. IT has become revolutionary through the use of
communication networks. Information can be transferred from one place to another without difficulty and
quickly.
