The TFTP (Trivial File Transfer Protocol) file transfer process works as follows:
1. Client sends a request for a file transfer to the server.
2. Server sends a response to the client indicating readiness.
3. Client sends the file to the server in blocks of data.
4. Server receives the blocks of data and sends an acknowledgement to the client for each block received.
5. If the server does not receive an acknowledgement for a block, it will retransmit that block.
6. Once all blocks have been received and acknowledged, the transfer is complete and the connection is closed.
TFTP does not provide encryption or authentication, and it lacks some of the features of other file transfer protocols such as FTP or SFTP. However, it is lightweight and easy to implement, making it useful for simple file transfer operations or for booting diskless workstations.
