What is the difference between UART port and serial port in a computer?

What is the difference, if any, between a UART port and a serial port in a computer?

Solution

  • UART is the abbreviation of Universal Asynchronous Receiver Transmitter, the name of the chip that enables the computer to communicate via a serial line (eg. RS-232, RS-485, RS-422).

    The serial port is the RS-232 interface (internally connected to the UART) of the computer.
