Learn in the textbookMail, File, and Operations Protocols
DefinitionFTP is the protocol for transferring files between computers on a network.
ExplanationIt works both for bringing a file from the server to your machine and for placing a local file on the server. The original FTP does not encrypt what it sends, so methods that support encryption are used where a secure exchange is needed.
AnalogyIt is a parcel courier rather than a letter service, moving the goods themselves. You can ship something out or collect something you left in storage.
Memory hookIt stands for File Transfer Protocol. Remember that the leading F is for File and it will not get mixed up with the mail protocols.
