Questions and Answers

What is the primary purpose of communication protocols?

To define the format, timing, and sequence of data transfer

To ensure compatible and efficient communication between devices

To control errors during data transfer

All of the above (correct)

What is the primary difference between RS-232 and RS-485 communication protocols?

RS-232 is a synchronous protocol, while RS-485 is an asynchronous protocol

RS-232 is a half-duplex protocol, while RS-485 is a full-duplex protocol

RS-232 supports multiple devices on the same bus, while RS-485 supports only a single device

RS-232 is commonly used for connecting peripheral devices, while RS-485 is often used in industrial applications (correct)

Which of the following is a characteristic of the UART (Universal Asynchronous Receiver/Transmitter) protocol?

It is a multi-master, multi-slave, packet-switched serial communication protocol
