MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The conversion from parallel to serial data transmission and vice versa takes place inside the interface circuits. Explanation: By doing this the interface circuits provide a better interconnection between devices.

Detailed explanation-2: -A serial port is able to transmit a single stream of data at a time. A parallel port is able to transmit multiple data streams at a time. A serial port sends data bit by bit after sending a bit at a time. A parallel port sends data by sending multiple bits in parallel fashion.

Detailed explanation-3: -If there is change in two or more bits of data sequence of transmitter to receiver, it is called “Multiple bit error”. This type of error occurs in both serial type and parallel type data communication networks.

Detailed explanation-4: -Which statement is Not True for serial communication? 1 point Data bits are organized in a specific order and transmitted one-bit at a time. It requires more wires compared to parallel communication. It is normally used for long-distance data transfer.

Detailed explanation-5: -Explanation: The RS232C is a standard interface for serial data transmission that defines the protocol and physical interface for transmitting serial data fairly easily between associated appliances and computers.
