Question

What is the full form of UART?

(a) Universal Asynchronous Receiver/Transmitter

(b) Universal Anti-Rectifying Transmitter

(c) Universal Asynchronous Radio Transmitter

(d) Universal Asynchronous Rectifier Transistor

I have been asked this question in examination.

My query is from Serial and Stream Communications in portion Arduino Programming of Arduino

Answer 1

Correct option is (a) Universal Asynchronous Receiver/Transmitter

To explain I would say: The UART architecture is a very important part of Serial Communications. It is not a protocol like the I2C or SPI, but a physical circuit configuration. Serial communication uses the UART architecture to send and receive the data serially from the computer.
