Computer Hardware Components

Hardware Components

Input Devices

• Keyboard: allows users to input text and commands
• Mouse: allows users to interact with the graphical user interface (GUI)
• Scanner: allows users to digitize physical documents and images
• Webcam: allows users to capture video and images
• Microphone: allows users to input audio

Processing Components

• Central Processing Unit (CPU): executes instructions and performs calculations
• Motherboard: connects and supports all hardware components
• Random Access Memory (RAM): temporarily stores data for fast access
• Graphics Processing Unit (GPU): handles graphics and video processing

Storage Components

• Hard Drive: stores data on a physical disk
• Solid State Drive (SSD): stores data in flash memory
• Optical Drive: reads and writes data to CDs, DVDs, and Blu-rays

Output Devices

• Monitor: displays visual output
• Speakers: produces audio output
• Printer: prints physical documents and images

Power Supply

• Converts Alternating Current (AC) power from the wall outlet to Direct Current (DC) power for the computer's components
• Provides power to all hardware components

Hardware Classification

• Input/Output (I/O) Devices: devices that interact with users and provide input/output functionality
• Processing Devices: devices that execute instructions and perform calculations
• Storage Devices: devices that store data
• Power Supply Units: devices that provide power to all hardware components
