Study Notes
- The documents provide an introduction to Information and Communications Technology (ICT)
- Examines its definition, evolution, components, power, classification, impact on media, current trends and ethical considerations
Definition of ICT
- ICT refers to all technologies utilized for gathering, processing, storing and presenting data
- Includes computers, software, networking technologies, communication tools and digital infrastructure
- IT (Information Technology) is a subset of ICT, specifically focused on the use of computers and software for managing information
Components of ICT
- Information: Processed data that provides knowledge and understanding
- Communication: The act of exchanging information through various means, including digital technologies
- Technology: The tools and techniques used to enhance daily activities, including communication and information sharing
Evolution of Technology
- Technology has evolved from simple tools to complex machines, significantly affecting daily life and work
Generations of Computers
- First-Generation Computers (1946-1959): Vacuum tube-based computers like ENIAC were large, expensive and limited
- Second-Generation Computers (1959-1965): Transistors replaced vacuum tubes, leading to smaller, faster and more reliable computers
- Third-Generation Computers (1965-1971): Integrated circuits (ICs) replaced transistors, further miniaturizing computers
- Fourth-Generation Computers (1971-1980): Very large-scale integrated (VLSI) circuits and microprocessors led to the development of personal computers
- Fifth-Generation Computers (1980-onwards): Ultra large-scale integration (ULSI) technology and artificial intelligence (AI) ushered in the era of intelligent computers
Components of a Computer
- Hardware: The physical components of a computer
- Input Devices: Allows users to enter data and instructions, such as keyboards, mouse, microphones, scanners and digital cameras
- Output Devices: Displays or transmits information, such as printers, monitors and speakers
- System Unit: The main enclosure containing the motherboard, CPU and storage devices
- Software: The programs and instructions that tell the hardware what to do
Power of Computers
- Computers are powerful due to:
- Speed: Ability to process vast amounts of data quickly
- Reliability: High dependability in performance
- Consistency: Consistent output when processing the same input
- Accuracy: Processes data with high accuracy, provided the input data is correct
- Communication: Communicates and shares data, instructions and information
Classification of Computers
