4. INTRODUCTION TO INFORMATION AND
COMMUNICATION TECHNOLOGY

6. INFORMATION and COMMUNICATION
TECHNOLOGY (ICT)
▪is defined as a diverse set of technological tools and
resources used to transmit, store, create, share or
exchange information. Unesco.org
▪is the use of computing and telecommunication
technologies, systems and tools to facilitate the
way information is created, collected, processed,
transmitted and stored. Techopedia.com

7. 3 Components of ICT
refers to the knowledge
obtained from reading,
investigation, study or
research.
INFORMATION
is an act of transmitting
messages. It is a
process whereby
information is
exchanged between
individuals using
symbols, signs or verbal
interactions.
COMMUNICATION
is the use of scientific
knowledge, experience
and resources to create
processes products
that fulfill human needs.
Technology is vital in
communication.

10. What Are The Primary
Components Of A Computer ?
•Input devices.
•Central Processing Unit
(containing the control unit
and the arithmetic/logic unit).
•Memory.
•Output devices.
•Storage devices.

11. Keyboard: Thekeyboard is
the main input device of the
computer that is used most
often. The keyboard is used to
perform all typing tasks on
the computer.
Input Devices

12. Mouse: The mouse is also the
main input device. With which the
pointer on the computer screen is
controlled. That is why it is also
called a pointing device. Mouse is
used to open, close, drag and
drop files, icons on a computer.

13. Scanner: A scanneris adevice
that capturesimagesfrom
photographic prints, posters,
magazine pages and similar
sources for computer editing
and display.

14. Webcam: A webcam is an input
device. A webcam is a camera that
you use to take pictures or video
conferences by connecting it to
your computer or laptop. You can
connect the webcam to your
computer with a cable, or you can
also use a wireless webcam.

15. CPU/Processor:Processor
stands for Central Processing
Unit (CPU). The CPU is the
brain of the computer and is
located on the motherboard.
Process Devices

16. Graphics Card: used to
process good videos and
images.

17. A printer isa device that accepts
text and graphic output from a
computer and transfers the
information topaper,

common typesofauxiliary
storageusedonpersonal
computersarefloppydisks,
harddisksandCD-ROM
drives.

20. is a set of
instructions, data
or programs used
to operate
computers and
execute specific
tasks.
SOFTWAREHARDWARE
refers to the physical
and visible components
of the system.
Computer is divided into 2
categories:

21. Hardware that keeps data inside
the computer for later use and
remains persistent even
whenthe computer has no
power.
EXTERNALINTERNAL
Describes a hardware
device installed outside
the computer.

28. Advantages of Using
Computers
•Speed: Computers can carry out instructions in less
than a millionth of a second.
•Accuracy : Computers can do the calculations
without errors and very accurately.
•Diligence : Computers are capable of performing
any task given to them repetitively.
•Storage Capacity : Computers can store large
volume of data and information on magnetic media.

29. •A Computer Network
is interconnection of
Computers to share
resources.
•Resources can be :
Information, Load,
Devices etc.
Networking

30. Types of Networks
On the basis of Size:
•Local Area Network (LAN)
Its a network of the computers locally i.e. in
one room, one building.
•Wide Area Network (WAN)
Its a network of the computers spread widely
geographically.

31. Types of Networks
On the basis of Size:
METROPOLITAN AREA NETWORK (MAN)
is a computer network that connects computers within a
metropolitan area.
Campus Area Network (CAN)

32. Benefits of Computer
Networks
•Information Sharing
•Device Sharing
•Load Sharing
•Mobility
•Fast Communication
•Anywhere Anytime Banking

33. How Does a Computer Know
what to do?
•It must be given a detailed list of instructions, called a
compute program or software, that tells it exactly
what to do.
•Before processing a specific job, the computer
program corresponding to that job must be stored in
memory.
•Once the program is stored in memory the compute
can start the operation by executing the program
instructions one after the other.
