ICT refers to technologies that provide access to information through communications and involves the use of computers and digital networks to store, retrieve, share, and manipulate information. The document discusses how ICT has evolved from early communication methods like drums to modern technologies like computers and the internet. It provides examples of how ICT is used in various aspects of everyday life such as education, banking, industry, and e-commerce to disseminate information and enhance communication.
INTRODUCTION TO ICT
- 1. CHAPTER 1: INFORMATION AND COMMUNICATION TECHNOLOGY AND SOCIETY (ICTS) Introduction to ICT
- 2. How our ancestor used to disperse information to others? In the early year of The Headman of the village Different rhythms signified Tanah Melayu, when was the one who announced different events.

Radio, television, satellites and the World Wide Web (www) are powerful tools that can be used.
- 7. Evolution of computers GENERATION COMPONENT FUNCTION PICTURE First Vacuum tubes • to store and process data 1940 - 1956 • example: ENIAC Second Transistor • to replace vacuum tubes in 1956 - 1963 computers • do not produced lots of heats and use less power • faster, cheaper and smaller Third Integrated circuits • replacing transistors 1964 - 1971 • more reliable and compact than computer made with transistor • cost less to manufacture Fourth Microprocessor • built onto a single silicon chip 1971 - Current • 100 times smaller than ENIAC Fifth Artificial • still in development Present and Intelligence • some application such as beyond voice recognition
- 8. Usage of ICT in everyday life EDUCATION Teacher use computers to research for teaching materials, participate in online forum and online conference. Students use computers as reference tools for looking information in the Internet. Researchers use computers to collect and process data. School administrators use computers for administrative purposes to ensure that entire operations run smoothly. BANKING Bank administrators can control the entire banking system and banking activities. To provide electronic banking services for customers. Businessman can save their time by using online services offered by banks.
- 9. INDUSTRY To help workers operate machine. To help researchers analyze and collect research data for future references. To help administrators to oversee and control entire operations in the factory. To facilitate production planning and control system. E-COMMERCE To make buying and selling activities faster and more efficient through Internet To connect online customers with suppliers to purchase products. This method can save time and cost. To help employees to communicate with their customers for any inquires and to get the latest updates inventory to be informed to the customers.
