What is 9600 baud?

9600 baud refers to a data transmission speed of 9600 bits per second. It is a common rate used in serial communication, particularly in applications like modems and microcontrollers. At this speed, each second, 9600 bits of data can be transmitted, allowing for efficient data exchange in various electronic devices. The baud rate is often used to set communication parameters for devices to ensure they can send and receive data correctly.
