5. INFORMATION &
COMMUNICATION TECHNOLOGY
What is ICT? It refers to all aspects of managing,
communicating and processing information.
It includes computer hardware and software,
telecommunications, audio-visual systems, cabling,
microwaves, radio waves, etc.
ICT is about saving time, being more effective, working
smarter and communicating faster and more effectively.

6. INFORMATION &
COMMUNICATION TECHNOLOGY
Different Types of ICT Services/ Uses
Various uses of ICT:
 Internet Services: The internet is a world-wide network
of computers that can be used in various ways enabling
faster and cheaper means of communication.
 Mobile Technology: With the introduction of smartphones
and tablet, mobile device can be used as a mobile phone,
GPS navigation device, web browser and instant messaging
client, game console…
 Office Productivity Applications: A suite of functions,
including word processing, spreadsheets, databases,
presentation software and an email application, e.g. MS
Office, Google Docs…

7. Main Types of Computers
 Desktop Computer – (often called PC), is a personal
computer that fits on or under a desk. It has a monitor or
another display, keyboard, mouse, and either a horizontal
or a vertical case.
 Laptop/ Notebook – is a lightweight, portable computer
that includes built-in screen, keyboard and touchpad, and
can operate from a built-in battery or electricity.
 Tablet – is a slate-shaped device, that comes in various
sizes and are mostly operated by touch screen. Tablets are
mobile computers larger than smartphones that draw
power from a rechargeable battery.

8. Main Types of Devices
 Smartphone – is a mobile phone offering advanced
computing and connectivity capabilities.
 They differ from ordinary phones in 2 ways: how they are built and
what functions they can perform.
 In terms of features, most smartphones support full email capabilities,
organizer, a built-in camera and GPS, the ability to read business
documents in several formats, & web browsing…
 The most common OSs used in smartphones are Google Android, Apple
iOS, and Microsoft Windows.
 Media Player – a multimedia player is a portable device
that store, organize and play media including audio,
images, and video files.
 Examples are the MP3, MP4 and iPod.
 Digital Camera – provide a convenient way of storing
videos or images on a microchip or memory card.

9. Main Parts of a Computer
 The Processor – The computer’s central processing unit,
or CPU, is the most important part of a computer.
The computer’s speed, performance and multitasking
abilities depend on the CPU.
 Random Access Memory (RAM) - RAM is the working
memory of the computer or device, most data goes into
the RAM
 Read Only Memory (ROM) –is an integrated circuit,
programmed with a specific, permanent set of instructions
and data when it is manufactured.
 Cache Memory – is a RAM that the CPU can access more
quickly than the RAM.

11. Parts of a Computer
 There are two basic parts that make up a
computer...
Hardware Software

12. Parts of a Computer (Cont’d)

13. Hardware
 Hardware is basically anything that you can touch
with your fingers.
Computer Case
CPU
Monitor
Keyboard & Mouse
Disk Drive, CD-ROM, DVD,
Hard Drive
Memory (RAM)
Speakers
Printer

14. Hardware (Cont’d)
 There are three
types/categories of
hardware
 Input Devices
 Output Devices
 Storage Devices

15. Input Devices
 Input basically means getting data into the computer to
be processed.
 Scanner
 Keyboard
 Mouse
 Trackpad/ Touch Pad
 Webcam
 Microphone, Speakers
 Docking Station
 Light Pen, Pointing Stick
 Touch Screen
 Bar Code Reader
 Joystick

16. Output Devices
 Output basically means getting data out of the computer.
 Printer
 Impact Printer
 Non-Impact Printer
 Printer Driver
 Print Spooler
 Screen
 Cathode Ray Tube (CRT)
 Liquid Crystal Display (LCD)
 Light-Emitting Diode (LED)
 Screen Resolution

17. Storage Devices
 Storage devices are both input and output devices in one.
A storage device is a place to keep data that has been
processed so that it can be retrieved at a later time to be
used again.
 Hard Disk
 Floppy Disk
 CD’s, DVD’s
 Magnetic Tape
 Flash Memory

18. Software
 Software is the programs and applications that tell the
computer what to do and how to look.
 Software is the set of instructions which the computer
needs to operate, e.g. to perform tasks, without
software, the computer cannot operate
 HTML is a type of computer programming language that
allows programmers to make web pages.
 The next 2 slides show what HTML codes look like and
the web page the codes produce.

21. Two Types of Software
 Operating System Software - Directs
all the activities and sets all the rules for
how the hardware and software will work
together.
 Examples would be: DOS, Windows, Unix,
Linux, Mac
 Application Software –
Task-Specific Programs that
work with operating system
software to help the computer
do specific types of work.

22. Basic types of application software
 Office Productivity Software - word processors,
spreadsheets, and database programs.
 Communication software - allows computers to
communicate with other computers.
 Social Networking Software – Facebook, Twitter…
 Media Applications – used for viewing and playing
multimedia files, such as Windows Media Player…
 Mobile Applications – AKA mobile app, designed to run
on smartphones and tablets.
 Graphics software - allow users to create and
manipulate graphics.
 Entertainment and Leisure software - Warcraft, Age
of Empires, Design Center, Solitaire…

23. Software

24. End-User Licensing Agreement
 The EULA, is the type of license used for most software.
 It is an agreement between the manufacturer and the
end-user of the software application, to accept the terms
and conditions of the EULA.
 When an end-user buys software, it does not mean that
the user now owns the software.
 It is the right to install and use.

25. Types of Software Licenses
 Proprietary License – grants the use of one or more copies
of the software under the EULA, but ownership remains with
the publisher.
 Open Source License – refers to any application of which the
source code is made available for use or modification. Open
source applications can usually be downloaded for free form
the internet or bought at a small fee.
 Shareware/ Trial Version License – they are copyright-
protected, but can be downloaded be a user to review and
evaluate before purchasing. They can either be a fully
functional time–limited version or a feature-limited version.
 Freeware License – Free of charge software, but not
available with the source code, e.g. Adobe Reader.
