TFTP
TFTP (Trivial File Transfer Protocol) is a simple, lock-step file transfer protocol that operates on UDP port 69, designed for transferring files between network devices with minimal overhead. It lacks authentication and directory listing features, making it suitable for bootstrapping diskless workstations or updating firmware on embedded systems. Due to its simplicity, it is often used in environments where security is not a primary concern, such as local networks or initial device configuration.
Developers should learn TFTP when working with network booting (PXE), firmware updates for routers or IoT devices, or in scenarios requiring lightweight file transfers without complex setup. It is particularly useful in embedded systems, network equipment management, and automated deployment processes where minimal protocol overhead is critical. However, due to its lack of security features, it should be avoided in untrusted networks or for sensitive data transfers.
