Understanding ASCII Format
ASCII (American Standard Code for Information Interchange) is a character encoding scheme used for text representation in computers and communication devices. It assigns a unique numeric value to each character.
Why 7-bit ASCII?
- ASCII originally uses a 7-bit binary number to represent characters, allowing for 128 unique symbols, which includes:
- Uppercase and lowercase letters (A-Z, a-z)
- Digits (0-9)
- Punctuation marks and control characters
- Although modern systems often use an 8-bit byte for data processing, the standard ASCII character set is fundamentally 7 bits. The extra bit in an 8-bit byte is frequently used for error checking or to represent extended character sets in various encoding schemes (like ISO-8859-1).
Control Connection Details
- In the context of a control connection (like FTP), commands are sent in a format that adheres to the 7-bit ASCII standard.
- This means that each character of the command is transmitted using 7 bits, ensuring compatibility across systems that interpret ASCII.
Conclusion
- Thus, the correct answer to the question is option 'B', 7-bit ASCII format, as it accurately reflects the encoding standard used for commands sent from client to server across the control connection.

Understanding ASCII Format
ASCII, which stands for American Standard Code for Information Interchange, is a character encoding standard that uses numerical values to represent characters. In the context of computer networks, particularly in control connections, the format of data transmission is crucial.
Why 7-bit ASCII?
- Character Representation:
- ASCII uses a 7-bit format to represent 128 characters, including letters, digits, punctuation, and control characters. This allows for efficient communication, especially for commands and replies.
- Control Connection:
- In networking, the control connection facilitates commands sent from the client to the server. These commands include requests for data, acknowledgments, and other instructions essential for establishing and maintaining a communication session.
Benefits of 7-bit ASCII
- Simplicity:
- The 7-bit format is straightforward, making it easy to implement and understand. It is widely adopted in various protocols, ensuring compatibility across different systems.
- Efficient Use of Bandwidth:
- By using only 7 bits for each character, the format conserves bandwidth, which is critical in scenarios where data transmission speed and efficiency are priorities.
- Legacy Compatibility:
- Many older systems and protocols rely on 7-bit ASCII. Maintaining this standard ensures that modern systems can communicate with legacy systems without issues.
Conclusion
In summary, the control connection between the client and server relies on 7-bit ASCII format for transmitting commands and replies. This format enables efficient communication, simplifying the interaction while supporting a wide range of characters essential for network operations.
