Step 1: Identify networking devices.
Networking devices are hardware components that enable interconnections between computers or other devices within a network, facilitating data exchange.
Step 2: Analyze each choice.
- Option (A) Gateway: A gateway serves as a connection point between dissimilar networks, enabling communication. It is indeed a networking device. - Option (B) Repeater: A repeater is a networking device that strengthens or reconstitutes network signals to expand coverage. - Option (C) MAN: A MAN (Metropolitan Area Network) describes a network's scope, not a physical device. - Option (D) Modem: A modem (modulator-demodulator) is a device that translates digital computer data into analog signals for transmission over phone lines, and vice versa. It functions as a networking device.
Step 3: Determine the correct devices.
Gateway and Modem are the correct networking devices among the options provided.
Final Answer: \[\boxed{\text{The correct networking devices are (A) Gateway and (D) Modem.}}\]
