What is the device that transmits and receives data?

• A. Transceiver
• B. Router
• C. Repeater
• D. Switch

Answer: (A)

Transceivers are the devices that both transmit and receive signals over a communication medium, allowing bidirectional data flow in a single unit. In networking, a transceiver handles converting electrical or optical signals to data frames and back, so a device can send data and listen for responses on the same path. This is different from a router, which primarily routes packets between networks, a switch, which forwards frames within a local network based on MAC addresses, and a repeater, which regenerates and rebroadcasts a signal to extend its reach. The key idea is that the transceiver is the combined transmitter and receiver hardware used to move data across the media.
