FTP vs TFTP
Major differences between FTP(File Transfer Protocol) & TFTP(Trivial File Transfer Protocol) Application layer protocols for file transfer:
| FTP | TFTP |
| General-purpose and hence, a more complex protocol | Special-purpose; much simpler |
| Needs more memory due to its complexity | Needs very small memory |
| Interactive | Unidirectional |
| Greater overhead & reliable control needed. | Less overhead and no control needed. |
| Due to above, it depends on TCP transport layer protocol | Due to above, it depends on UDP transport layer protocol |
| Uses TCP port #20 as data port & port #21 as the connection port | Uses UDP port #69 |
| Used over the WWW | Used only on local networks due to lack of security |
