A. Local area network
B. Wide area network
C. Modulator-Demodulator
D. All of the above
Check Answer
The correct answer is B) Wide area network.
A wide area network (WAN) is a network that covers a large geographic area and is typically used for communication between different locations or offices. The telephone system is an example of a WAN, as it enables communication over long distances through the use of telephone lines and other infrastructure.
A local area network (LAN) is a network that covers a smaller geographic area, typically a building or campus, and is used for communication between devices within that area.
A modulator-Demodulator (modem) is a device used to transmit digital data over a communication line by modulating the digital data into an analog signal and demodulating the analog signal back into digital data at the receiving end.
