The Trivial File Transfer Protocol (TFTP) is a simple protocol used for transferring files over a network. It operates on the User Datagram Protocol (UDP), which allows for faster data transmission without the overhead of establishing a connection. TFTP is commonly used for tasks like booting devices and transferring configuration files, especially in environments where simplicity and speed are prioritized. TFTP is designed to be easy to implement, making it suitable for devices with limited resources, such as routers and embedded systems. However, it lacks security features like authentication and encryption, which makes it less suitable for transferring sensitive data compared to more robust protocols like File Transfer Protocol (FTP).
