2.3 Modern Microcomputers
Today’s microcomputers, including desktops, laptops, and tablets, are highly advanced. They feature multi-core processors, high-speed storage, and powerful graphics capabilities, making them suitable for gaming, business, and creative work.
3. Components of a Microcomputer
Every microcomputer, or personal computer, consists of essential hardware and software components.
3.1 Hardware Components
- Microprocessor (CPU) – The brain of the computer that processes data.
- Memory (RAM) – Temporary storage that allows quick access to data.
- Storage Devices (HDD/SSD) – Permanent storage for files and programs.
- Motherboard – The main circuit board that connects all components.
- Power Supply Unit (PSU) – Converts electricity into usable power for the computer.
- Input Devices – Includes keyboard, mouse, and touchscreens.
- Output Devices – Includes monitors, printers, and speakers.
3.2 Software Components
- Operating System (OS) – Software that manages hardware and applications (e.g., Windows, macOS, Linux).
- Application Software – Programs used for tasks like word processing, web browsing, and gaming.
- Firmware – Software embedded into hardware components for essential functions.
4. Types of Microcomputers
Microcomputers come in various forms, each designed for specific uses.
