UART means Universal Asynchronous Receiver/Transmitter which converts the bytes it receives from the computer along parallel circuits into a single serial bit stream for outbound transmission. And also receives data in serial form and converts it into parallel form and sent to the processor.

UART (Universal Asynchronous Receiver/Transmitter)
UART is a type of device that can be used to interface a parallel data format with external equipment's serial format. Here is a detailed explanation:
What is UART?
- UART is a hardware device that converts parallel data (multiple bits sent simultaneously) into serial data (one bit at a time) for transmission and vice versa for reception.
- It acts as a bridge between parallel and serial formats, making communication between devices with different data formats possible.
Working of UART
- UART operates by sending data bit by bit over a single data line. It includes a transmitter and a receiver, each with its own shift register.
- The transmitter converts parallel data into a serial format by sending one bit at a time, along with start and stop bits for synchronization.
- The receiver converts serial data back into parallel data by receiving one bit at a time and reconstructing the original parallel data.
Interface with External Equipment
- UART is commonly used to connect devices like microcontrollers, sensors, and peripherals to a computer or other external equipment that uses a serial communication protocol.
- It allows seamless data transfer between devices that use parallel and serial data formats, enabling communication and control in various applications.
In conclusion, UART plays a crucial role in interfacing parallel data formats with external equipment's serial format, facilitating efficient data exchange and communication between devices with different data formats.
