What is the symbol set used in hexadecimal number systems?

The correct answer is 0 - 9, A - F.

Key Points

• The hexadecimal number system is a base-16 numeral system that uses 16 distinct symbols.
• These symbols include digits 0 to 9 and letters A to F, where A represents 10, B represents 11, and so on, up to F which represents 15.
• Hexadecimal is commonly used in computing and digital electronics as a more human-friendly representation of binary-coded values.
• This system is particularly useful for representing memory addresses, color codes in web design (e.g., #FFFFFF for white), and machine-level instructions.
• Hexadecimal is widely applied in programming languages such as HTML, CSS, and assembly language.

Additional Information

• Binary Number System:
  • The binary system is a base-2 numeral system that uses only two symbols: 0 and 1.
  • It is the foundation for all modern computer systems and digital circuits.
  • Every hexadecimal digit corresponds to exactly four binary digits, making conversions between the two systems straightforward.
• Decimal Number System:
  • The decimal system is a base-10 numeral system and uses digits 0 to 9.
  • This is the most commonly used number system in everyday life.
  • Decimal numbers can be converted into hexadecimal using division and remainder calculations.
• Octal Number System:
  • The octal system is a base-8 numeral system that uses digits 0 to 7.
  • It is sometimes used in computing as a shorthand for binary numbers.
  • Each octal digit corresponds to three binary digits.
• Applications of Hexadecimal:
  • Hexadecimal is widely used in memory addressing and debugging.
  • It is also employed in defining color codes for web design (e.g., #FF5733).
  • Microcontrollers and embedded systems often use hexadecimal to represent machine-level instructions.
