2. What is ICT?

ICT stands for Information and Communication Technology.

ICT refers to the technologies, devices, software and communication systems used to create, collect, store, process, retrieve, transmit and share information.

ICT combines computing and communication technologies to enable people and organisations to work with information and communicate efficiently.

Example:

When a student prepares a presentation on a computer, stores it digitally and shares it with a teacher through email or a learning platform, several ICT technologies are being used together.

3. Understanding Information, Communication and Technology

Term Meaning Example
Information Processed, organised or meaningful data that can be used to understand something or make decisions. A student's report card containing marks and grades.
Communication The process of exchanging information between people or systems. Sending a message through email.
Technology Tools, systems and techniques developed to solve problems or accomplish tasks. Computers, smartphones, networks and software.
ICT = Information + Communication + Technology

ICT becomes especially powerful when computing technologies and communication networks work together.

4. Data and Information

Data refers to raw facts and observations that may not have been organised or interpreted.

Information is data that has been processed or organised so that it has meaning or usefulness.

Data Processing Information
78, 82, 91, 86 Calculate the average. Average = 84.25
Example:

Individual marks are data. A report showing total marks, percentage, grade and performance summary is information.

5. How an ICT System Works

A basic ICT system can be understood through the flow of data and information:

Input
→
Processing
→
Storage
→
Output
→
Communication
Stage Purpose Example
Input Enter or collect data. Typing marks into a spreadsheet.
Processing Manipulate or analyse data. Calculating percentages.
Storage Save data and information for later use. Saving a file on a storage drive.
Output Present processed information. Displaying a chart on a screen.
Communication Transmit information between people or systems. Sharing a document through a network.

6. Components of ICT

ICT systems generally involve several interconnected components.

1. Hardware

Physical components of an ICT system that can be seen and touched.

Examples: computer, keyboard, mouse, monitor, printer, scanner, smartphone, router.

2. Software
