*Question E8D10:
What are some of the differences between the Baudot digital code and ASCII?*  

*Correct Answer is  B: Baudot uses 5 data bits per character, ASCII uses 7 or 8; Baudot uses 2 characters as letters/figures shift codes, ASCII has no letters/figures shift code*  

### AI Response: (may contain errors)  

The correct answer is **B**: Baudot uses 5 data bits per character, ASCII uses 7 or 8; Baudot uses 2 characters as letters/figures shift codes, ASCII has no letters/figures shift code.

### Explanation of the Correct Answer:
- **Baudot Code**:
  - Uses **5 data bits** per character.
  - Has **2 special characters** that act as shift codes to switch between letters and figures (numbers/symbols).
  
- **ASCII (American Standard Code for Information Interchange)**:
  - Typically uses **7 bits** for standard ASCII, but can extend to **8 bits** for extended ASCII.
  - Does **not** have a shift code; it directly represents characters without needing to switch modes.

### Why the Other Choices are Incorrect:
- **Choice A**:
  - Incorrect because Baudot uses **5 bits**, not 4, and it does have shift codes.
  
- **Choice C**:
  - Incorrect because Baudot uses **5 bits**, not 6, and it does have shift codes.
  
- **Choice D**:
  - Incorrect because Baudot uses **5 bits**, not 7, and it does have shift codes.

### Summary of Key Points:
- **Baudot Code**:
  - 5 bits per character
  - 2 shift codes for letters/figures

- **ASCII**:
  - 7 or 8 bits per character
  - No shift codes; each character is represented directly

This understanding of the differences between Baudot and ASCII is crucial for the Extra Class exam, especially in the context of digital communications.
