Detailed explanation-1: -With asynchronous transmission, a large text document is organized into long strings of letters (or characters) that make up the words within the sentences and paragraphs. These characters are sent over the communication link one at a time and reassembled at the remote location.
Detailed explanation-2: -Answers. Explanation: The data is transmitted asynchronously in RS232 which enhance long distance communication, whereas SPI, I2C offers short distance communication, and therefore, they are using synchronous data transmission.
Detailed explanation-3: -Edit online. The term synchronous is used to describe a continuous and consistent timed transfer of data blocks. These types of connections are used when large amounts of data must be transferred very quickly from one location to the other.
Detailed explanation-4: -Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data. Data communication is the transmission of digital messages to external devices.
