AND COMMUNICATION
TECHNOLOGY AND SOCIETY
(ICTS)
Introduction to ICT
How our ancestor used to
disperse information to others?
In the early year of The Headman of the village Different rhythms signified
Tanah Melayu, when was the one who announced different events. The rhythm of

or radio. The ‘Beduk’ time of prayers or even when was different from the rhythm
play an important role. the village was in danger. used to announce prayers.
Definition of ICT
ICT is a technology required for information
processing, in particular, the use electronics
computers, communication devices and application
software to convert, store, protect, process, transmit
and retrieve information from anywhere, anytime.
Information
1. Information refers to the knowledge obtained from reading,
investigation, study or research.
3. The tools to transmit information are the telephone, television and
radio.
5. We need information to make decisions and to predict the future.
For example, scientists can detect the formation of a tsunami using
the latest technology and warn the public to avoid disasters in the
affected areas.

performing drama and poetry. With the advent of
technology, these ‘older’ forms of communication are less
utilized as compared to the use of the internet, e-mail or
video conferencing.
Technology
1. Is the use of scientific knowledge, experience and resources
to create processes and product that fulfill human needs?
3. Aiding Communication - telephone and fax machines are the
devices used in extending communication.
5. Spreading Information – To broadcast information such as
news or weather reports effectively. Radio, television,
satellites and the World Wide Web (www) are powerful
tools that can be used.
Evolution of computers
GENERATION COMPONENT FUNCTION PICTURE
First Vacuum tubes • to store and process data
1940 - 1956 • example: ENIAC
Second Transistor • to replace vacuum tubes in
1956 - 1963 computers
• do not produced lots of heats
and use less power
• faster, cheaper and smaller
Third Integrated circuits • replacing transistors
1964 - 1971 • more reliable and compact
than computer made with
transistor
• cost less to manufacture
Fourth Microprocessor • built onto a single silicon chip
1971 - Current • 100 times smaller than ENIAC
Fifth Artificial • still in development
Present and Intelligence • some application such as
beyond voice recognition
Usage of ICT in everyday life
