Which option best describes a character in computing?

• A. A memory address
• B. A sequence of bits forming a byte
• C. A basic unit of information that represents a letter, number, symbol, or control code
• D. A boolean flag

Answer: (C)

A character in computing is a basic unit of information that represents a letter, number, symbol, or control code. This is the symbol used in text, and computers store and display it by mapping it to binary values through encodings like ASCII or Unicode. While a memory address points to where data lives, and a byte is a specific 8-bit storage unit that can hold a character in many encodings, those ideas describe data storage and format rather than what a character itself represents. A boolean flag is just true/false information used to control logic, not a textual symbol. So, the best description is the one that defines a character as a fundamental symbol used to represent text, encoded in binary.
