The modem is the abbreviation of Modulator (Modulator) and Demodulator (Demodulator). The Chinese is called a modem (called the data machine by Hong Kong and Taiwan). According to the homonym of Modem, it is called "cat" by relatives. It is a device that converts a digital signal into an analog signal by modulation at the transmitting end and converts the analog signal into a digital signal by demodulating at the receiving end. The external modem (4 photos) is called modulation, which converts the digital signal into an analog signal transmitted on the telephone line; demodulation converts the analog signal into a digital signal. Synonymous with a modem. The English language of the modem is MODEM, which is used as a "translator" for analog and digital signals. There are two types of electronic signals, one is "analog signal" and the other is "digital signal". The telephone line we use transmits analog signals, and the digital signals are transmitted between PCs. So when you want to connect your computer to the Internet via a telephone line, you must use a modem to "translate" two different signals. After connecting to the Internet, when the PC sends information to the Internet, because the telephone line transmits an analog signal, it is necessary to use a modem to "translate" the digital signal into an analog signal before it can be transmitted to the Internet. This process is called "modulation." ". When a PC obtains information from the Internet, since the information transmitted from the Internet through the telephone line is an analog signal, the PC wants to understand them, and must also use the modem to "translate". This process is called "demodulation." . In general, it is called "modulation and demodulation."
