What is keyboard in a computer?

In computing, a keyboard refers to a peripheral device that allows users to input data, commands, and text into a computer or other electronic device. It consists of a set of keys or buttons, each representing either a specific character, letter, number, symbol, or function.

Keyboards can come in various forms and layouts, but the most common type is the QWERTY keyboard, named after the arrangement of its first six letters in the top row. The QWERTY layout is widely used and standardized for English-language keyboards.

Keyboards are typically connected to a computer via a wired USB connection or wirelessly through Bluetooth or other wireless technologies. They can be integrated into laptops or tablets as a built-in component or used as separate, standalone devices for desktop computers.

Functions of a computer keyboard include:

1. Text Input: Users can type letters, numbers, symbols, and other characters to input text into various applications such as word processors, web browsers, messaging platforms, and more.

2. Command Execution: Keyboards enable users to execute commands and shortcuts within operating systems and software applications. For example, pressing Ctrl + C (or Command + C on Mac) copies selected text or files, while Ctrl + V (or Command + V on Mac) pastes them.

3. Navigation: Keyboards often include arrow keys and other navigation keys that allow users to move the cursor, scroll through documents, or navigate within interfaces.

4. Special Functions: Some keyboards come with specialized keys for specific functions such as multimedia control (play, pause, volume control), launching applications, adjusting screen brightness, or accessing shortcuts.

Modern keyboards can also have additional features like backlighting, ergonomic designs, mechanical switches for improved tactile feedback, and customizable keys to cater to the specific needs of users, gamers, programmers, or professionals in various industries.
