The advantage of parallel communication is it is fast but its drawback is it use more number of I/O (input-output) lines. streaming can be achieved using the latest generation of high-bit rate (one-way) acoustic modems. What type of communication does the radio use? Modems communicate with each other using a MODULATION method, which translates between digital computer data and analog telephone signals. If the number is less than or equal to 9, the program should output the nu … When the data signal is transmitted directly over the medium, this is called baseband transmission. Same string or word will appear over the LCD, then press D/OK to send the input string to the server. At its most extreme, a software modem is just a DAA (data access arrangement): the most basic part of a modem that makes the physical interface between the relatively high voltage analog phone line and public phone network (on one side) and the lower voltage, digital modem circuits (on the other), ensuring the two can safely talk to one another. Asynchronous serial data communication is widely used for character-oriented transmission, and block-oriented data transfers use the Synchronous method. For transmission over an analog telephone line—which was once the most popular way to access the internet—the modem converts data between analog and digital formats in real time for two-way network communication. DTE can be a terminal or a computer. Broadband is the technique of using modulation and FDM to transmit multiple data channels of a common medium.
