12. What is IT?
• INFORMATION
– When information is entered into and stored in a
computer, it is generally referred to as data. After
processing (such as formatting and printing),
output data can again be perceived as
information.
– Information is data that has been processed in
such a way as to be meaningful to the person who
receives it
12

13. • Information can be obtained from various sources: you
can be told information, for example through a lecture
or a television programme, or you can find information
through your own research.
• Information is essential to finding your route to
university in the morning, writing an essay, getting the
right ingredients for a recipe, conducting an
experiment, renting a flat, filling in a job application
form, exam revision and for many, many other
everyday and not-so-everyday tasks.
Why we need information?

14. CONT..
• Examples of data are weights, prices, costs,
numbers of items sold, employee names, product
names, addresses, tax codes, registration marks
etc.
• Examples of information are Time Table, Merit
List, Report card, printed documents, pay slips,
receipts, reports etc.
• Marks obtained by students and their roll
numbers form data, the report card/sheet is the
information.

15. • TECHNOLOGY
– Is the technology required for information
processing, use of electronic computers,
communication devices and software applications
to convert , store, protect, process, transmit and
retrieve information from anywhere, anytime.
15

16. Cont..
• Historically, the term information technology
referred to all the technologies associated
with the gathering, processing, storing, and

• However, with the passage of time and the
progress of technologies, is now used
generally to embrace both computer and
communication technologies.

33. Introducing Computer Systems
• Computers were originally designed for the purpose of
scientific calculations.
• Computers are no longer just calculating machines, as
implied by the name, but are also tools for
communications and are also able to act as audio and
video players and so forth.
• Computers, however, are now commonplace in
schools, offices and homes and are used to store,
process and retrieve enormous quantities of
information for an incredible variety of purposes.
• Many communications facilities are now more or less
like computers with special uses
