A. Network
B. Communication channel
C. Modem
D. Bus
Check Answer
The correct answer is B) Communication channel.
A communication channel is a medium through which data can be transferred between two locations. It can be physical (e.g. copper wires, fiber optics) or wireless (e.g. radio waves, microwaves) and can be used for various types of data transmission, such as voice, video, and text.
Option A (Network) is incorrect because a network is a collection of interconnected devices that can communicate and share resources with each other, not a medium of communication itself.
Option C (Modem) is incorrect because a modem is a device that converts digital signals into analog signals (modulation) for transmission over a communication channel and converts analog signals back into digital signals (demodulation) for reception by a digital device.
Option D (Bus) is incorrect because a bus is a communication system that transfers data between components within a computer or between computers in a network, not a medium of communication between two locations.
