FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Modems convert analog network signals into digital while routers manage the distribution of signals across devices. Modems and routers are essential parts of any network topology. However, the former translates analog network signals arriving via cables into a digital format for consumption by endpoint devices.

Detailed explanation-2: -Digital signals can convey information with less noise, distortion, and interference. Digital circuits can be reproduced easily in mass quantities at comparatively low costs. Digital signal processing is more flexible because DSP operations can be altered using digitally programmable systems.

Detailed explanation-3: -Analog signal’s prime advantage is the infinite data that they have. The data density is very high. These signals use less bandwidth. The accuracy is another advantage of Analog signals.

Detailed explanation-4: -The modem converts (or modulates) the digital signal, which doesn’t transmit efficiently over a phone line, into an analog signal that does. Once the analog signal reaches its intended target, the receiving modem converts it back into a digital signal (demodulation).
