About Hexadecimal Encoding

Hexadecimal (base-16) is a numeral system that uses 16 distinct symbols (0-9 and A-F) to represent values. Each hex digit represents four binary digits (bits), making it a convenient way to represent binary data.

  • Memory Addresses: 0x7FFF
  • Binary Data: File inspection and debugging
  • Character Codes: ASCII/Unicode values
