Which device is commonly used to enter data into a computer?

• A. Monitor
• B. Keyboard
• C. Speaker
• D. Hard Drive

Answer: (B)

The keyboard is a primary input device designed specifically for entering data into a computer. It allows users to input text, commands, and various types of data through its keys, which include letters, numbers, function keys, and special characters. The interaction between a user and a computer is often initiated through the keyboard, making it an essential tool for typing documents, programming, and performing various tasks in software applications. Other devices serve different functions and are not used for data entry in the same way. For instance, a monitor displays visual output from the computer but does not facilitate data input. Similarly, a speaker outputs audio, providing sound output rather than input. A hard drive serves as storage, holding data and files rather than enabling user input. Thus, the keyboard stands out as the most recognized and widely used device for entering data into a computer system.
