FTP allows two computers to connect over the Internet so that files can be transferred between a client and server. It was created in 1971 at MIT by Abhay Bhushan to transfer data over the new ARPANET. FTP works through a request, response, transfer, terminate cycle. It converts files to binary for transmission and allows downloading and uploading of files. While over 30 years old, FTP continues to be used and modified to meet user demands.
File transfer protocol (ftp)
- 2. FILE TRANSFER PROTOCOL • Allows two computers, a client and server, to connect over the Internet. • During this connection the server and client are able to then transfer various files. • This is done through converting files into binary and then transmitting the data, this concise process allows someone to download or upload a file to the internet.
- 3. HISTORY OF FTP • April 16, 1971 by Abhay Bhushan from MIT • US DoD, Advanced Research Projects Agency Network • ARPANET was the first network to allow for data to be transferred through computers • Bhushan created a protocol that would easily allow data to be transferred through this new network
- 5. FTP: REQUEST • This request is initiated by the client • Allowing the File Transfer Protocol to begin • Sub-commands • store, delete, lookup, open and close • Allows client to interact with the server before they download or upload a file
- 6. FTP: RESPONSE • Server will inform the client that it is ready to either receive or send a file • The sub-commands used in this transaction are “ready to send” and “ready to receive”
- 7. FTP: TRANSFER • The actual transaction will occur in the transfer step FTP: TERMINATE • Two types of terminate transactions • successful terminate • unsuccessful terminate
- 8. File Transfer Protocol Cycle
- 9. THE FUTURE? So where can a protocol that has been in use for over 30 years go from here? It has been modified and improved throughout the years to keep up with user demands. It is fairly safe to say that File Transfer Protocol will still be in use for the future.
