Study Notes
Hardware Overview
- Hardware encompasses all physical components of a computer system, contrasting with software which is intangible.
Input Devices
- Devices that interact with the computer to send data include keyboard, mouse, and scanners.
- Key features of input devices:
- Keyboard: Allows input of letters and symbols; includes typing keypad, navigation keys, numeric keypad, escape key, function keys, and light indicators.
- Mouse: Detects user movements and clicks for interaction with the computer.
Output Devices
- Devices that provide information from the computer to the user include monitors and printers.
- Key output devices:
- Monitor: Displays information; types include CRT (cathode ray tube), LCD (liquid crystal display), and touchscreen.
- Printer: Outputs text and images on physical media like paper.
Storage Devices
- Hardware used to store processed data includes hard disk drives which are non-volatile and typically the largest storage component in a computer.
Communication Devices
- Devices that send and receive information include network interface cards that facilitate file sharing between computers.
System Unit
- Houses all computer peripherals such as mouse, keyboard, monitors, audio speakers, and printers.
- Contains the main circuit board (motherboard) integrating the central processing unit (CPU), main system memory, and control circuitry for peripherals.
Processing and Power Components
- Central Processing Unit (CPU): Acts as the brain or engine of the computer, executing instructions and managing processes.
- Power Supply: Provides electrical power to all components of the computer.
Specialized Hardware
- Video Card: A circuit board that processes images for display on monitors, TVs, or projectors.
- Sound Card: Enables sound manipulation and production, facilitating audio output through speakers.
