Study Notes
Introduction to ICT
- Information: Processed data that leads to knowledge.
- Communication: Method of transmitting knowledge.
- Technology: Tools that enhance information and communication dissemination.
- ICT: Involves various technologies like mobile phones, computers, and the Internet for processing and managing data.
History of Computers
- Abacus: Considered the first calculator, used for hundreds of years.
- Charles Babbage: Conceptualized the first programmable mechanical computer in the 19th century, but it was never built due to complexity and funding issues.
- ENIAC: Developed in 1943, recognized as the first electronic computer, using electrical switches to store numbers.
- UNIVAC: Launched in 1951 as the first commercially produced digital computer; Dwight Eisenhower was the first president to use it.
Generations of Computers
- 1st Generation: Utilized vacuum tubes for circuitry.
- 2nd Generation: Involved transistors, making computers more reliable.
- 3rd Generation: Used integrated circuits for improved performance.
- 4th Generation: Featured microprocessors, further enhancing computing power.
- 5th Generation: Incorporates artificial intelligence, enabling machines to mimic human capabilities.
Trends in ICT
- Digital Transformation: Integration of digital technology in business operations.
- Digital Healthcare: Use of technology to improve healthcare services.
- Mobile Payments: Financial transactions conducted via mobile devices.
- Network Connectivity: Advancements in 5G technology and the Internet of Things (IoT).
Computer Fundamentals
- Computer: An electronic device that receives, processes, stores data, and produces output.
- Data: Raw, unprocessed facts, including text, numbers, and multimedia components.
- Hardware: Includes input devices (keyboard), output devices (monitor), and storage (flash drives).
- Software: Divided into application software (specific tasks) and system software (operating systems).
Operating Systems
- Operating System: Essential software for running the computer, including utility programs.
- Device Driver: Enables the OS to interact with hardware components.
- Central Processing Unit (CPU): The main chip that processes data and performs operations.
Types of Operating Systems
- Personal/desktop OS: Installed on single-user computers (e.g., Mac OS, Linux, Windows).
- Mobile OS: Designed for handheld devices.
- Server OS: Manages networks between linked computers.
- Embedded OS: Operates within specific devices like ATMs and media players.
Additional Concepts
- Clock Speed: The rate at which a CPU executes instructions, measured in instructions per second.
- Registers: Small memory spaces used by the Arithmetic Logic Unit (ALU) for calculations.
- Machine Cycle: The sequence of steps executed by a computer's processor for machine language instructions.
- Boot Process: A series of steps to start a computer and load the operating system.
