How many characters can be addressed by the 7-bit ASCII character table and 16-bit Unicode?

The 7-bit ASCII character table can represent 128 unique characters. This is because the 7 bits can be configured into (2^7), which equals 128. ASCII includes characters such as the English alphabet (both uppercase and lowercase), digits, punctuation marks, and control characters.

On the other hand, 16-bit Unicode can represent up to 65,536 different characters, as it can encode values from (0) to (2^{16} - 1). This extensive range allows Unicode to include a vast array of characters from multiple languages, special symbols, emojis, and more.

Therefore, 128 characters for ASCII and 65,536 characters for Unicode are accurately reflected in the correct choice.
