*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)  

The correct answer to the question about the advantages of using ASCII code for data communications is:

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

### Explanation of the Correct Answer:
- **ASCII (American Standard Code for Information Interchange)** is a character encoding standard that uses 7 bits to represent characters. This allows for 128 different characters, which include:
  - Uppercase letters (A-Z)
  - Lowercase letters (a-z)
  - Digits (0-9)
  - Special characters and control codes

- The ability to represent both uppercase and lowercase letters is a significant advantage because it allows for more expressive text communication, which is essential in many applications, such as programming and data representation.

### Explanation of the Incorrect Choices:
- **A: It includes built-in error correction features**
  - This is incorrect because ASCII itself does not include any error correction features. Error correction is typically handled by higher-level protocols or additional error-checking methods, not by the ASCII encoding.

- **B: It contains fewer information bits per character than any other code**
  - This statement is misleading. While ASCII uses 7 bits per character, there are other encoding schemes (like UTF-8 for example) that can use more bits but also support a much larger set of characters. Thus, ASCII does not necessarily have fewer bits than all other codes.

- **D: It uses one character as a shift code to send numeric and special characters**
  - This is incorrect because ASCII does not use a shift code. Instead, it directly encodes numeric and special characters within its 7-bit structure. Shift codes are more relevant to other encoding systems, such as those used in certain types of keyboard input.

### Summary:
- ASCII's ability to represent both uppercase and lowercase letters makes it versatile for text communication.
- Other options either misrepresent ASCII's capabilities or confuse it with other encoding methods.

This understanding of ASCII will help you in recognizing its role in data communications and its advantages over other encoding systems.
