What is the purpose of an input device?

The purpose of an input device is to allow users to enter data into a computer. Input devices are essential for facilitating interaction between the user and the computer system, enabling the user to provide commands, data, and instructions. Common examples of input devices include keyboards, mice, scanners, and microphones. These devices convert user actions into signals that the computer can understand and process, thereby making it possible for users to communicate with the system effectively.

In contrast, display devices are responsible for conveying information to users, while processing refers to how the computer handles and manipulates the data provided through input devices. Network management involves maintaining and controlling network connections, which is unrelated to the primary function of input devices. Thus, the correct answer highlights the fundamental role of input devices in the data-entry process within computer systems.
