当今的调制解调器是诸多通信高科技技术的结晶。十多年来,调制解调器经历了由非智能到智能、低速到高速、模拟到数字、单一数据通信到数据、语音、图形、图像通信的转变。Modem是什么 调制解调器(Modem)分别由调制(Modulate)和解调(Demodulate)组合而成,我们可以从字面上理解为:在一端,数据经过调制后,被转换成适合在电话网上传送的模拟信号,借助电话线发送到另一端;在另一端将电话线所传送过来的模拟信号经解调后,转换成计算机能够识别的数字信号,以使对方计算机能够接收。PPP、TCP等协议都建立在这一基础上。
Today’s modems are the culmination of many communications high-tech technologies. For over a decade, modems have undergone a shift from non-intelligent to smart, low to high speed, analog to digital, single data communications to data, voice, graphics, and image communications. Modem What is a modem Modem Modulation Modulation and Demodulate, we can literally interpreted as: at one end, the data is modulated, is converted to analog signals for transmission over the telephone network , By telephone lines sent to the other end; at the other end of the analog signal transmitted by the telephone line after demodulation, converted into digital signals recognized by the computer, so that the other computer can receive. PPP, TCP and other agreements are based on this foundation.
