Alphanumeric keyboard

Imagine you have a special writing tool, like a pen or a pencil, that lets you write letters and numbers on a piece of paper. An alphanumeric keyboard is just like that, but it is a tool you can use to write letters, numbers, and other symbols on a computer.

The keyboard looks like a rectangular box with lots of small buttons on it. Each button has a letter, number, or symbol on it. When you press a button, the computer receives a signal that tells it which button you pressed. Then it shows up on the screen.

The keyboard is called "alphanumeric" because it can write both letters (like A, B, and C) and numbers (like 1, 2, and 3). This makes it easier to type words and numbers on the computer.

There are also special keys on the keyboard, such as the shift key, the enter key, and the backspace key. These keys help you to do things like capitalize letters, start a new line, and erase mistakes.

Overall, the alphanumeric keyboard is a very important tool for typing on the computer. It helps you to communicate with others, do schoolwork, and play games.
