Which symbols can be represented by one byte?

One byte is a unit of digital information that can represent 256 different values, ranging from 0 to 255. This capability allows for the representation of various types of symbols, including digits, letters (both uppercase and lowercase), special characters, and control codes. In many encoding schemes, such as ASCII (American Standard Code for Information Interchange), the characters typically included are:

• Digits: 0 through 9

• Uppercase letters: A through Z

• Lowercase letters: a through z

• Special characters: Various symbols like punctuation marks and others

While the option chosen specifies digits 0 to 9 and special characters, it's important to note that one byte can actually encompass a broader variety of symbols. The correct representation aligns with the understanding that a byte has enough capacity to encode numbers, letters, and control codes. Thus, the inclusion of just digits and special characters doesn't fully utilize the byte's potential for representing the complete set of characters available within the byte's range of values.
