Keyboard
Overview
- A keyboard is an input device that allows users to interact with a computer by typing commands, data, and instructions.
- It is a crucial component of a computer system, enabling users to communicate with the computer.
Components
- Keys: The keyboard consists of a set of keys, each with a specific function, such as alphanumeric characters, symbols, and commands.
- Switches: Underneath each key, there is a switch that registers the keystroke and sends the signal to the computer.
- Circuit board: The switches are connected to a circuit board, which processes the keystroke signals and sends them to the computer.
Types of Keyboards
- Wired keyboard: Connected to the computer using a physical cable.
- Wireless keyboard: Uses radio frequency (RF) or Bluetooth technology to connect to the computer without a physical cable.
- Mechanical keyboard: Features individual mechanical switches under each key, providing tactile feedback and improved durability.
- Membrane keyboard: Uses a single layer of conductive material under the keys, which registers keystrokes when pressed.
Keyboard Layouts
- QWERTY: The most common keyboard layout, designed to slow down typing to prevent keys from jamming together on mechanical typewriters.
- QWERTZ: Used in some European countries, it swaps the "Y" and "Z" keys.
- AZERTY: Used in France and Belgium, it has a unique layout designed to facilitate typing in French.
Additional Features
- Function keys: Special keys that provide shortcuts to common functions, such as volume control, screen brightness, and multimedia playback.
- Navigation keys:Keys used for navigating, such as arrow keys, page up/down, and home/end.
- Ergonomic features: Some keyboards feature ergonomic designs, such as curved or split keyboards, to reduce strain on the hands and wrists.
