All Types of Computer Components and Their Mechanism A computer system is made up of several interconnected components that work together to process data and produce meaningful output. These components can be broadly classified into hardware components, software components, input devices, output devices, processing units, and storage units. Each component has a specific mechanism and function. 1. Input Components Input components are used to enter data and instructions into the computer system. These devices convert human-readable information into machine-readable form. Mechanism: Input devices capture physical data (text, sound, image, or movement) and convert it into digital signals (binary form) that the computer can process. Examples: Keyboard, Mouse, Scanner, Microphone, Webcam, Touchscreen 2. Central Processing Unit (CPU) The CPU is the brain of the computer. It performs all calculations, decision-making, and control operations. Mechanism: The CPU works in a continuou...

All Types of Wireless Connectivity in the World 1. Radio Wave Communication Radio wave communication is one of the oldest forms of wireless technology. In this system, information is converted into low-frequency radio waves and transmitted through an antenna. These waves travel through the air and are received by another antenna at the receiver end. Radio broadcasting, television transmission, and walkie-talkies use this method. Radio waves can cover long distances and penetrate obstacles, but they suffer from noise and offer low data transmission rates. 2. Microwave Communication Microwave communication uses high-frequency electromagnetic waves ranging from 1 GHz to 300 GHz. It operates mainly on a line-of-sight principle, meaning the transmitter and receiver must be directly visible to each other. Microwave links are widely used in satellite communication, mobile tower connections, and radar systems. This technology supports high data rates, but signals are easily blocked by...
