What is one advantage of using ASCII rather than Baudot code?
D
Answer
Antennas and transmission lines
Type
A
The larger character set allows store-and-forward
B
ASCII characters contain fewer information bits
C
ASCII includes built-in error correction
D
It includes both upper and lower case text characters in the code
Answer Notes
Baudot code is an older 5-bit digital code originally used for radioteletype (RTTY). Because a 5-bit code can only produce 32 unique combinations, it relies on special shift characters to switch between letters and figures, and it natively supports only uppercase text.
ASCII (American Standard Code for Information Interchange) is a 7-bit code, which allows for 128 unique character combinations. This larger capacity means ASCII can natively represent both uppercase and lowercase letters, numbers, and a wide variety of punctuation and control characters without needing clumsy shift codes.
While ASCII uses more information bits than Baudot, this trade-off is highly advantageous for modern computing and readable text. Neither code includes built-in error correction natively; error management relies on other protocol layers.
