Question
What is one advantage of using ASCII code for data communications?
Answer Options
- A) It includes built-in error correction features
- B) It contains fewer information bits per character than any other code
- C) It is possible to transmit both uppercase and lowercase text
- D) It uses one character as a shift code to send numeric and special characters
Correct Answer: C
Explanation
The \text{ASCII} (American Standard Code for Information Interchange) code uses 7 or 8 data bits per character, giving it up to 256 unique codes. This large number of available codes is a major advantage over older, simpler codes like Baudot, which only use 5 data bits.
Since \text{ASCII} has a sufficient number of bits to encode all required symbols, one key advantage of using \text{ASCII} code for data communications is that it is possible to transmit both uppercase and lowercase text simultaneously, without needing to transmit an explicit ‘shift’ character to change the meaning of the codes. This allows for a much more natural and flexible conversation style.
