What is the primary function of an input device?

The primary function of an input device is to enter data into the computer. Input devices, such as keyboards, mice, scanners, and microphones, facilitate user interaction by allowing users to input commands, create documents, and provide information that the computer can process. This data can be in various forms, including text, images, sound, or other types of commands that the computer needs in order to execute tasks and perform operations.

In contrast, other options focus on different functionalities. Displaying information is the role of output devices, like monitors or printers, which present results to the user. Storing files permanently pertains to storage devices, such as hard drives or solid-state drives, that retain information long-term. Managing network traffic relates to networking equipment, such as routers and switches, which control data flow but do not function as input devices. Thus, the importance of input devices lies in their role in initiating communication and data transfer to the computer system.
