What does this mean?
BRAINSTROM!
3. WHAT IS IT/ICT?
• Information
Technology (IT)/Information
Communication Technology (ICT) is
how technology is used to manage
information.
• The gathering, processing, storing, and
giving vocal, pictorial, textual and
numerical information through
computing or telecommunication.
6. PARTS OF A
COMPUTER!
• There are
different parts of a
computer which
fall under two large
categories:
1.HARDWARE
2.SOFTWARE
7. PARTS OF A COMPUTER
• HARDWARE: is the physical parts
of a computer , they are also called
peripheral devices.
• 4 categories:
1.INPUT
2.OUTPUT
3.PROCESSING
4.STORAGE
8. HARDWARE
1. INPUT: any piece of hardware equipment that
is used to provide data and used to give your
computer directions.
2. PROCCESSING: any piece of hardware
equipment that is used to process the information
that is being received from an input device
3. OUTPUT: any piece of hardware equipment that
is used to give data from a computer after it has
been processed.
4. STORAGE: piece of hardware which saves
information so it can be recalled later.
9. The History of the Computer
What hardware devices were mentioned in the video and what
type of device are they?

11. SOFTWARE
• is the non physical
components of a computer
which perform very specific
tasks.
12. THE “INS” of a
Computer
• Networked Environment
• Operating systems
• Common Interface
13. NETWORKING
• A computer network is a collection of
hardware components and computers connected
by communication channels that allow resources
and information to be shared.
• At least one computer is able to send/receive
data to/from at lease one other computer.
14. Different types of Networks:
• LAN: local area network-when computers
are located close together-same building.
• WAN: wide area network-when computers
are further apart and are connected by
telephone lines-same area but different
buildings.
• CAN: campus area networks-when
computers are within a limited area-a
school campus.
• HAN: home area network-when computers
16. OPERATING SYSTEMS
• An operating system is a program that runs other
programs which enable the computer’s hardware to
communicate with the computer and which enables
software to run.
• Operating systems are found on almost any device
that contains a computer, including cell phones.
17. OPERATING SYSTEMS
• 4 Different types of Operating systems:
1. Multi-user: allows multiple people to run
the same program at the same time.
2. Multi-processing: allows a program to run
on more than one central processing unit.
3. Multi-tasking: allows more than one
program to run at a time.
4.Multi-threading: allows different parts of
one program to run at the same time.
19. INTERFACE
• Interface is how an application’s or programs
graphic or textual controls are laid out and
how they respond to user activity.
20. INTERFACE
• On the desktop of your computer what do you
see? And what do they mean and do?
• In a chart you will be required to find the
definitions of different items that are on your
desktop and explain their significance to a
computer workstation.
