Explain the concept of Serial Communication and UART.
Answer
Serial communication transmits data bit-by-bit sequentially over a single communication line.
Serial communication transmits data bit-by-bit sequentially over a single communication line, making it cost-effective for long distances. It can be synchronous or asynchronous.
UART (Universal Asynchronous Receiver-Transmitter) is a chip that handles asynchronous serial communication. It takes parallel data from the CPU and converts it to a serial bit stream (with start, parity, and stop bits) for transmission, and vice versa for reception.
