A UART is usually an individual (or part of an) integrated circuit (IC) used for serial communications over a computer or peripheral device serial port. One or more UART peripherals are commonly integrated in microcontroller chips. Specialised UARTs are used for automobiles, smart cards and SIMs.
The transmitting UART is connected to a controlling data bus that sends data in a parallel form. From this, the data will now be transmitted on the transmission line (wire) serially, bit by bit, to the receiving UART. This, in turn, will convert the serial data into parallel for the receiving device.
The UART port provides a simplified UART interface to other peripherals or hosts, supporting full-duplex, DMA, and asynchronous transfer of serial data. The UART port includes support for five to eight data bits, and none, even, or odd parity. A frame is terminated by one and a half or two stop bits.

Universal Asynchronous Receiver/Transmitter or UART for short represents the hardware - integrated circuit, used for the serial communication through the serial port. UART is a standalone integrated circuit (IC) but also as a part of microcontrollers.
