Asynchronous Transmission is a method of data communication where information is sent without a synchronized clock signal. Instead, data is transmitted in small packets, each containing start and stop bits that indicate the beginning and end of the transmission. This allows the sender and receiver to operate independently, making it easier to manage data flow. This type of transmission is commonly used in serial communication systems, such as RS-232 and UART. It is particularly useful for applications where data is sent intermittently, as it reduces the need for continuous synchronization and allows for more flexible communication between devices.
