Which type of device sends data to another device but does not receive data?

The correct answer is an output device. An output device is specifically designed to send data from a computer to another device or to the user, without any capability to receive data back. Common examples include monitors, printers, and speakers, which take processed data and convert it into a form usable or perceivable by a human.

Input devices, on the other hand, are designed to send data to the computer but can receive signals back for processing, which is not the primary role of an output device. Storage devices, such as hard drives or flash drives, hold data for future use but do not transmit information in real-time like output devices do. Networking devices, such as routers and switches, facilitate communication between devices and can send and receive data, meaning they do not fit the description of one-way data transmission either. Understanding these distinctions helps clarify why output devices are the correct choice in this context.
