Is UART Different from USART on the Arduino Uno?
Question:
UART stands for Universal Asynchronous Receiver Transmitter, and what is used on something like the Arduino Uno for programming and various interface tasks, correct?
Alternatively, USART stands for Universal Synchronous and Asynchronous Receiver Transmitter, and is something different, correct (e.g. NOT used with Arduino Uno)?
------------------------
It seems if you look this up you get some differing answers, e.g.: https://www.electronicwings.com/arduino/usart-in-arduino-uno versus https://en.wikipedia.org/wiki/Universal_synchronous_and_asynchronous_receiver-transmitter
------------------------
I believe what I said in the first two sentences is correct, but I'm doing a class on Arduino serial usage so I need to be accurate!

Arduino has on-chip USART or UART which is used to communicate data serially. Using USART, we can communicate with PC/laptop or serial devices like GSM, GPS, etc.
A universal synchronous and asynchronous receiver-transmitter (USART, programmable communications interface or PCI) is a type of a serial interface device that can be programmed to communicate asynchronously or synchronously. See universal asynchronous receiver-transmitter (UART) for a discussion of the asynchronous capabilities of these devices.
