An input device is designed to capture and send data to a computer or other processing unit. The type of data it receives is referred to as information, which can include various forms of user-generated content such as keyboard inputs, mouse movements, or data from sensors. This information is then processed by the computer to perform specific tasks, display results, or facilitate user interaction.

In contrast, command signals typically refer to instructions sent to devices rather than data being inputted. Processed data denotes information that has already undergone processing, making it distinct from what input devices receive. Lastly, output signals represent the results generated by a system or device to convey information back to the user, which is also not relevant to the data being received by input devices. Thus, the role of input devices is primarily centered around receiving and transmitting information to be worked on, making "information" the correct choice.
