What are some of the differences between the Baudot digital code and ASCII?
- A.Baudot uses 4 data bits per character, ASCII uses 7 or 8; Baudot uses 1 character as a letters/figures shift code, ASCII has no letters/figures code
- 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 (correct answer)
- C.Baudot uses 6 data bits per character, ASCII uses 7 or 8; Baudot has no letters/figures shift code, ASCII uses 2 letters/figures shift codes
- D.Baudot uses 7 data bits per character, ASCII uses 8; Baudot has no letters/figures shift code, ASCII uses 2 letters/figures shift codes
WhyBaudot uses 5 data bits per character to ASCII's 7 or 8, and needs 2 characters as letters/figures shift codes where ASCII needs none. Baudot uses 5 data bits per character (compared to ASCII's 7 or 8) and needs 2 dedicated shift characters to switch between its letters and figures character sets, since 5 bits alone can't represent enough unique codes for both letters and figures/symbols at once, while ASCII's larger 7- or 8-bit codes don't need any such shift mechanism, answer B. The other options misstate either the bit counts involved or which code actually needs the letters/figures shift scheme.
