Study Notes

Module 1: Computer Essentials

ICT (Information and Communication Technology): The study of methods for storing, processing, and sharing information using computer science.
Hardware: The physical components of an ICT device, like keyboards, screens, and mice.
Computer Types: Desktop PCs, laptops, tablets, phablets, smartphones, media players, and digital cameras.
Processor (CPU): The central processing unit that performs calculations, controls internal processes, and manages peripherals.
ALU (Arithmetic Logic Unit): Executes logical and mathematical operations.
CU (Control Unit): Coordinates processing tasks.
Cache Memory: Fast temporary memory for the ALU to store data.
Processor Register: Stores addresses, instructions, and values.
Bus: Facilitates communication between internal and external computer components.
Processor Speed: Measured in Hertz (Hz), representing the number of operations per second (e.g., 3 GHz is 3 billion cycles per second).
RAM (Random Access Memory): A quick-access, volatile memory that temporarily stores data. Data is lost when the computer is switched off.
Mass Storage: Permanent storage for data and programs (including hard disks, pen drives, memory cards, CDs, DVDs).
Peripherals: Devices that connect to the computer for input (e.g., keyboard, mouse) and output (e.g., monitor, printer).
Integrated Devices: Multi-functional devices often built into the computer.
Input Devices: Keyboard, mouse, touchpad, scanner, webcam, microphone, trackball, touchscreen
Output Devices: Screen/monitor (LCD or CRT), printer, speakers, docking station, touchscreen
