Number System Quick Reference

Binary System (Base 2)

  • Uses only digits 0 and 1
  • Each position represents a power of 2
  • Example: 1010 = 8 + 0 + 2 + 0 = 10 in decimal
  • ASCII 'A' = 01000001 in binary

Hexadecimal System (Base 16)

  • Uses digits 0-9 and letters A-F
  • Each position represents a power of 16
  • Example: FF = 15×16 + 15 = 255 in decimal
  • ASCII 'A' = 41 in hexadecimal

Practical Examples

Text "Hello" Conversions:

  • Binary: 01001000 01100101 01101100 01101100 01101111
  • Hexadecimal: 48 65 6C 6C 6F
  • Decimal ASCII: 72 101 108 108 111

Common Programming Values:

  • NULL character: 00000000 (Binary), 00 (Hex)
  • Space character: 00100000 (Binary), 20 (Hex)
  • Number '0': 00110000 (Binary), 30 (Hex)
  • Letter 'A': 01000001 (Binary), 41 (Hex)
  • Letter 'a': 01100001 (Binary), 61 (Hex)

Frequently asked questions

Why do programmers use hexadecimal?

One hex digit represents exactly four bits, so a byte is always two hex digits (00–FF). That is far shorter and easier to read than eight binary digits.

How is the letter "A" stored in binary?

In ASCII and UTF-8, "A" has the value 65, which is 01000001 in binary and 41 in hexadecimal.
