*Question E8D11:
What is one advantage of using ASCII code for data communications?*  

*Correct Answer is  C: It is possible to transmit both uppercase and lowercase text*  

### AI Response: (may contain errors)  

ASCII (American Standard Code for Information Interchange) is a character encoding standard used in data communications. Let's examine why the correct answer is correct and why the other choices are incorrect:

1. **Correct Answer: C - It is possible to transmit both uppercase and lowercase text**

   - ASCII includes a set of 128 characters, which covers both uppercase (A-Z) and lowercase (a-z) letters. This allows for the transmission of text that maintains the distinction between uppercase and lowercase, which is important for readability and meaning in many contexts.

2. **Why the other choices are incorrect:**

   - **A: It includes built-in error correction features**

     - ASCII itself does not include error correction features. It is simply a character encoding standard. Error correction is typically handled by other protocols or systems layered on top of ASCII.

   - **B: It contains fewer information bits per character than any other code**

     - ASCII uses 7 bits per character, which is not necessarily fewer than other encoding systems. For example, some systems use 5-bit or 6-bit codes, but these have a more limited character set.

   - **D: It uses one character as a shift code to send numeric and special characters**

     - ASCII does not use a shift code for numeric and special characters. Each character, including numbers and special symbols, has its own unique 7-bit code in the ASCII table.

In summary, the primary advantage of ASCII in this context is its ability to represent both uppercase and lowercase text, which is essential for clear and accurate communication.
