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.

UNIT 1: HARDWARE and SOFTWARE

PARTS OF A COMPUTER! • There are different parts of a computer which fall under two large categories:

1.HARDWARE2.SOFTWARE

PARTS OF A COMPUTER• HARDWARE: is the physical parts of a

computer , they are also called peripheral devices.

• 4 categories:1.INPUT2.OUTPUT3.PROCESSING4.STORAGE

HARDWARE 1. INPUT:INPUT: any piece of hardware equipment that is used to provide data and used to give your computer directions.

2. PROCCESSING:2. PROCCESSING: any piece of hardware equipment that is used to process the information that is being received from an input device

3. OUTPUT:3. OUTPUT: any piece of hardware equipment that is used to give data from a computer after it has been processed.

4. STORAGE:4. STORAGE: piece of hardware which saves information so it can be recalled later.

The History of the Computer

PARTS OF A COMPUTER

SOFTWARE

• is the non physical components of a computer which perform very specific tasks.

THE “INS” of a Computer• Networked Environment• Operating systems• Common Interface

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.

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 are contained within a persons home.

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.

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.

Common Operating Systems

• Windows

• MAC OS

• LINUX

INTERFACE• Interface is how an application’s or programs

graphic or textual controls are laid out and how they respond to user activity.

• 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.
