A keyboard is a primary input device used to enter text, numbers, and commands into a computer or other digital devices. It consists of a set of keys (buttons) arranged in a specific layout (e.g., QWERTY, AZERTY) that correspond to letters, numbers, symbols, and functions.
Types of Keyboards

- Membrane Keyboard – Uses pressure pads; quieter but less durable.
- Virtual Keyboard – On-screen keyboard (used in smartphones & touchscreen devices).
- Ergonomic Keyboard – Designed to reduce strain (curved or split layout).
- Gaming Keyboard – Extra macro keys, RGB lighting, and fast response.
- Wireless Keyboard – Connects via Bluetooth or USB receiver.
