51304511-200 调制解调器 能把计算机的数字信号翻译

51304511-200 调制解调器，是调制器和解调器的缩写，一种计算机硬件。它能把计算机的数字信号翻译成可沿普通电话线传送的模拟信号，而这些模拟信号又可被线路另一端的另一个调制解调器接收，并译成计算机可懂的语言。这一简单过程完成了两台计算机间的通信。调制解调器由调制器和解调器两部分组成，其中调制器的作用是将计算机串行口产生的数字信号调制成可以通过电话线传输的模拟信号，而解调器的作用是将输入计算机的模拟信号转换成相应的数字信号，送入计算机接口。因此，调制解调器在通信中起到了至关重要的作用，是模拟信号和数字信号的“翻译员”。调制解调器的英文是MODEM，根据谐音，人们亲昵地称之为“猫”。调制解调器按照传输模式可以分为外置式、内置式、PCMCIA插卡式和机架式等。此外，调制解调器还有多种传输速率和传输协议可供选择，以满足不同用户的需求。总的来说，51304511-200 调制解调器是实现通信的重要设备之一，能够将数字信号和模拟信号进行相互转换，从而完成两台计算机之间的通信过程。

51304511-200 modem, abbreviated as modulator and demodulator, is a type of computer hardware. It can translate computer digital signals into analog signals that can be transmitted along ordinary telephone lines, and these analog signals can be received by another modem at the other end of the line and translated into language that the computer can understand. This simple process completes the communication between two computers. Modem consists of modulator and demodulator. The role of modulator is to modulate digital signals generated by computer serial port into analog signals that can be transmitted through telephone line, while the role of demodulator is to convert analog signals input into corresponding digital signals and send them to computer interface. Therefore, modems play a crucial role in communication, serving as the “translators” of analog and digital signals. The English name for a modem is MODEM, which is affectionately referred to as “cat” according to its homophones. According to the transmission mode, modems can be divided into external, built-in, PCMCIA plug-in, and rack type. In addition, modems have multiple transmission rates and protocols to choose from to meet the needs of different users. Overall, the 51304511-200 modem is one of the important devices for communication, which can convert digital signals and analog signals to complete the communication process between two computers.
