The keyboard is an essential input device of a computer that allows users to communicate with the machine by typing characters and commands. While it may seem like a simple tool, the keyboard is composed of several different parts that work together to provide a smooth and efficient typing experience. In this article, we will explore the different components of a computer keyboard and their functions.

What are the parts of a computer keyboard?

1. Alphanumeric keys: These are the letters (A-Z) and numbers (0-9) that form the main body of the keyboard and are used for typing.

2. Function keys: Positioned at the top row of the keyboard, these special keys (F1-F12) perform various functions depending on the application or operating system being used.

3. Modifier keys: These keys, including Shift, Control, Alt/Option, and Command/Windows, modify the function of other keys to enable specific commands or input variations.

4. Cursor keys: Also known as arrow keys, they consist of four directional keys (up, down, left, right) and are used to move the cursor or selection in text or graphical interfaces.

5. Numeric keypad: Positioned on the right side of a standard keyboard, this section includes numeric keys, arithmetic operators, and a enter key for quick numerical input.
