What device is used to enter data and issue commands to a computer?

The chosen answer is correct because an input device is specifically designed to allow users to enter data and issue commands to a computer. These devices enable communication between the user and the computer system by translating user actions into a format that the computer can understand. Common examples of input devices include keyboards, mice, scanners, and microphones, all of which facilitate various types of data entry and command issuance.

In contrast, output devices are used to convey information from the computer to the user, such as monitors and printers, and do not serve the purpose of data entry. Storage devices are designed for data retention, capable of storing data for long-term use, like hard drives and USB flash drives, but they do not allow direct data entry or command issuance in real time. Display devices are types of output devices that present visual information to users, focusing solely on output rather than data input.
