Question

Which statement accurately describes the difference between a traditional modem and an ISDN line?

a) Modem uses analog signals; ISDN uses digital signals
b) Modem is faster than ISDN
c) Modem requires a telephone line; ISDN does not
d) ISDN is outdated technology

Answer 1

Modems use analog signals, while ISDN uses digital signals. Modems require a telephone line, while ISDN does not. ISDN is not outdated technology.

Step-by-step explanation:

The correct statement that describes the difference between a traditional modem and an ISDN line is that modems use analog signals while ISDN uses digital signals. Modems convert digital signals from your computer into analog signals that can be transmitted over telephone lines, and then convert them back into digital signals at the receiving end. On the other hand, ISDN lines use digital signals directly, resulting in faster and more reliable data transmission.

In addition, modems usually require a telephone line to establish a connection while ISDN does not necessarily require a telephone line. Instead, an ISDN line uses a separate digital line to provide faster and more reliable connections for voice, video, and data transmission.

It is important to note that ISDN is not outdated technology, but rather an alternative to traditional modems. While ISDN is less commonly used today due to the availability of high-speed broadband internet, it still offers advantages in certain situations, such as dedicated connections and faster upload speeds.
