What is one advantage of using ASCII code for data communications?
- A.It includes built-in error correction features
- B.It contains fewer information bits per character than any other code
- C.It is possible to transmit both uppercase and lowercase text (correct answer)
- D.It uses one character as a shift code to send numeric and special characters
WhyOne advantage of ASCII code for data communications is that it's possible to transmit both uppercase and lowercase text. One real advantage of ASCII code for data communications is that it's possible to transmit both uppercase and lowercase text, since ASCII's larger character set has room for separate codes for each case, unlike more limited older codes, answer C. ASCII doesn't include built-in error correction, doesn't use fewer information bits per character than every other code (it actually uses more bits than compact codes like Baudot), and doesn't rely on a letters/figures shift character the way Baudot does.
