A UART (Universal Asynchronous Receiver/Transmitter) is the microchip with programming that controls a computer's interface to its attached serial devices. Specifically, it provides the computer with the RS-232C Data Terminal Equipment ( DTE ) interface so that it can "talk" to and exchange data with modems and other serial devices. As part of this interface, the UART also: * Converts the bytes it receives from the computer along parallel circuits into a single serial bit stream for outbound transmission * On inbound transmission, converts the serial bit stream into the bytes that the computer handles * Adds a parity bit (if it's been selected) on outbound transmissions and checks the parity of incoming bytes (if selected) and discards the parity bit * Adds start and stop delineators on outbound and strips them from inbound transmissions * Handles interrupt s from the keyboard and mouse (which are serial devices with special port s) * May handle other kinds of interrupt and device management that require coordinating the computer's speed of operation with device speeds More advanced UARTs provide some amount of buffering of data so that the computer and serial devices data streams remain coordinated. The most recent UART, the 16550, has a 16-byte buffer that can get filled before the computer's processor needs to handle the data. The original UART was the 8250. If you purchase an internal modem today, it probably includes a 16550 UART (although you should ask when you buy it). According to modem manufacturer US Robotics, external modems do not include a UART. If you have an older computer, you may want to add an internal 16550 to get the most out of your external modem.
UART (Universal Asynchronous receiver - transmitter). It is sometimes referred to as UART 16550.
Universal Asynchronous Reciever Transmitter (UART) controls the speed of Serial Ports on Computers.
The letters 'UART' is an acronym that stands for Universal Asynchronous Receiver/Transmitter. It is a piece of computer hardware that translates data.

if the stop bits does not appear when it is supposed to, the UART considers the entire word to be garbled and will report a framing error ..
A UART does not convert an analog signal into a digital signal. It converts a serial digital signal into a parallel digital signal, and vice versa. The letters UART stand for Universal Asynchronous Receiver Transmitter. It is, fundamentally, a pair of shift registers.
Its not, it just happens to be convenient. Other standards for UART communication include RS-422, RS-423, RS-481, and various others.
UART Protocol stands for Universal Asynchronous Receiver/Transmitter. It is a piece of computer hardware that is used to translate data that runs between parallel and serial forms.
Uart basically stands universal asynchronous receiver transmitter.As it is asynchronous so there is no need for synchronization between transmitter and receiver.For detailed information click on to www.wikipedia .org.
Yes. Actually we can communicate with ZigBee module through UART. So UART itself is a full Duplex communication. So we can use ZigBee for full Duplex communication.
