Detailed explanation-1: -What is serial communication? Serial communication is a communication method that uses one or two transmission lines to send and receive data, and that data is continuously sent and received one bit at a time.
Detailed explanation-2: -Explanation: The serial communication requires less number of conductors and thus it is cheaper. It is slow as the bits are transmitted one by one along with start, stop and parity bits. Explanation: Serial communication is more popular for communication over longer distances as it requires less number of conductors.
Detailed explanation-3: -Which of the following is not a serial protocol? Explanation: The RS232 is a physical interface. It does not follow the serial protocol.
Detailed explanation-4: -In serial connection, a minimum of three lines are used for communication: transmit (TX), receive (RX), and ground (GND). Some high-speed serial communication systems use additional control signals for synchronization, such as CTS, DTR, and so on.
