A Universal Asynchronous Receiver-Transmitter (UART) is a hardware communication protocol used for asynchronous serial communication between devices. It converts parallel data from a microcontroller into serial form for transmission and vice versa, using start and stop bits to frame the data without needing a clock signal to synchronize the data stream.

A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system, combining a processor, memory, and input/output peripherals on a single chip. They are widely used in automatically controlled devices and systems, ranging from simple home appliances to complex industrial machinery.

Transmission refers to the process of transferring something from one place, person, or thing to another, and is a fundamental concept in various fields such as physics, biology, and communication. Understanding transmission involves examining the mechanisms, mediums, and factors that influence the efficiency and effectiveness of this transfer process.

A clock signal is a periodic waveform used to synchronize the operations of electronic components in digital circuits, ensuring that data is processed in a coordinated manner. It is fundamental to the functioning of microprocessors, memory systems, and communication interfaces, providing a timing reference that dictates the pace of data flow and processing activities.
