A router is a networking device that forwards data on a network.
Input device
A Microphone does not output sound. It accepts sound. It is an input device.
I would consider it to be an input and output device , because it puts out a message that the user would have recorded previously , and it accepts inward a message from a caller . it also allows messages to be replayed / output sound to the user .
A palindromic word for a device that revolves could be "rotor." It reads the same forwards and backwards.

its a switch
When a packet arrives at the network layer on the sender's device, it is encapsulated into a frame whose destination MAC address is all fs (FF-FF-FF...). The switch connected to the sender's device recognizes the all fs MAC address as a broadcast message and hence forwards it to all its ports.
The message goes through unilateral wires to another person's device.
In a bus topology, messages travel along a single central cable, known as the bus, which connects all devices in the network. When a device wants to send a message, it broadcasts the data onto the bus, and the message travels in both directions along the cable. Each device on the network checks the incoming data and accepts the message if it is addressed to it; otherwise, it ignores it. This method allows for efficient communication, but if the bus cable fails, the entire network can go down.
A unicast message is a message directed to a specific device on a network (just one specific device). It would have a destination IP address that corresponds to that device.
