Which device is mainly used to type letters and numbers?

Answer and explanation

Correct answer: Keyboard

A keyboard is the primary input device for entering letters, numbers, punctuation, and special symbols, so option A is correct. It converts key presses into signals that the computer can process. A speaker produces sound, a printer creates paper output, and a scanner captures printed material as digital input. The key distinction is that the keyboard is designed for typed alphanumeric entry.
