Which of the following correctly identifies ASCII and EBCDIC?

The correct identification of ASCII and EBCDIC as 8-bit codes is rooted in their design and structure. Both ASCII (American Standard Code for Information Interchange) and EBCDIC (Extended Binary Coded Decimal Interchange Code) are character encoding schemes that use 8 bits (1 byte) to represent each character.

In ASCII, there are 128 standard characters, which include letters, digits, punctuation marks, and control characters, represented using the first 7 bits, while the 8th bit can be used for additional characters, depending on the extension employed. EBCDIC, developed by IBM, also utilizes an 8-bit format, allowing for a range of 256 different characters, which makes it suitable for various applications, especially in older mainframe systems.

Understanding that both of these character sets are encoded within an 8-bit framework helps clarify how data is represented in computing. This distinction excludes 16-bit, 32-bit, and 64-bit codes, which pertain to different types of data representations and are not relevant to the structure of these character encoding systems.
