What code represents alphanumeric characters in binary?

The choice of ASCII as the correct answer is based on its role in representing alphanumeric characters in a binary format. ASCII, which stands for American Standard Code for Information Interchange, is a character encoding standard that uses 7 bits to represent characters, allowing for a total of 128 different symbols, including letters, digits, punctuation marks, and control characters. Each character is mapped to a specific binary value, making it a foundational encoding system in computing.

While UTF-8 is also a character encoding that can represent alphanumeric characters and is capable of encoding all possible characters in Unicode, it is more complex as it uses a variable number of bytes for each character. It is a superset of ASCII, meaning it can represent all ASCII characters while also including additional characters from other languages and symbols. However, the question specifically asks for a code that directly represents alphanumeric characters in binary, which is more accurately defined by ASCII.

BIP-32 refers to Bitcoin Improvement Proposal 32, which is related to hierarchical deterministic wallets in cryptocurrency and is not relevant to character encoding. EPUB is a digital eBook format that encapsulates text and images, but it does not specifically relate to the representation of alphanumeric characters in binary. Therefore, ASCII is the most
