Which of the following is NOT a valid mode of data transfer in FTP?

Correct option is E

FTP supports three modes of data transfer:
1. Stream Mode: Data is sent as a continuous stream.
2. Block Mode: Data is divided into blocks with headers for error handling.
3. Compressed Mode: Data is compressed before being sent.
Binary and ASCII are not modes of transfer but rather file types used in FTP for data representation.
Important Key Points:
1. FTP uses port 21 for control and port 20 for data transfer.
2. Data types in FTP include ASCII (text files) and Binary (non-text files).
Knowledge Booster:
· ASCII Mode: Text files are transferred with proper newline conversions.
· Binary Mode: Non-text files are transferred as-is without modification.
