Detailed explanation-1: -The correct answer is Modem. Modem stands for Modulator-Demodulator. Modulation and Demodulation are coding and decoding processes where the analog signals are converted into digital signals and vice versa for proper transmission of data.
Detailed explanation-2: -A modem is a type of network device that modulates and demodulates analog carrier signals to encode and decode digital information for processing. It transmits the data by modulating carrier wave signals to encode the digital information.
Detailed explanation-3: -Dial-Up Modems As previously discussed, a computer’s digital signals must be converted to analog signals before they are transmitted over standard telephone lines. The communications device that performs this conversion is a modem, sometimes called a dial-up modem.
