This document discusses ICT systems and the differences between data and information. It defines ICT as using technology for input, processing, storage and transfer of data and output of information. A system is described as a set of connected parts forming a whole with input, process and output. An ICT system is the same but uses technology and outputs directly to a human or other ICT system. Data on its own is meaningless facts or numbers, but becomes information when given relevance through processing. Examples of ICT systems and diagrams are provided to illustrate these concepts.

2. Lesson Objectives
 To know the definition of ICT, System and ICT
System.
 To be able to provide examples of a System and an ICT
System.
 To understand what the difference is between Data
and Information is and how that change takes place.

3. What is ICT?
 In pairs discuss what you think ICT?
 Information and Communication Technology is the
use of technology for the input, processing, storage
and transfer of data and the output of information.

4. ICT Systems
 Find/Create a definition for a ‘System’ and an ‘ICT
System’
 System – “A set of connected things or parts forming a
complex whole” – Input, Process, Output
 ICT System – The same as a System but it uses
technology and the output goes directly to a human or
another ICT system.

5. System – Input, Process, Output
Data Information
Input Process Output
Take Food Add up the Produce the
Order Separate Bill
Items

6. ICT System –
Input, Process, Output
Data Information
Input Process Output
Photos from Crop and Improved
Digital Airbrush in Photos
Camera Graphics Displayed
Software

7. Task - Systems
 Draw the Input, Process & Output diagram for both a
System and ICT System.
 Annotate both diagrams with an example.

8. ICT System –
Input, Storage, Process, Output
Data Data Information
Input Storage Process Output

9. What is Data?
 In pairs discuss what you think Data is?
 Data can be defined as a set of recorded facts, numbers
or events that have no meaning.
 Data is meaningless until it is given relevance.
 All data on a computer is represented by 0’s and 1’s.

10. Types of Data
 What are the different types of data?
 Text
 Numeric
 Boolean/Logical
 Images
 Audio
 Video
