Hexadecimal (Hex) is a base-16 numeral system widely used in computer science and electronics. It uses 16 symbols to represent numbers: digits 0 to 9 and letters A to F.

Basics of Hexadecimal

The hexadecimal system uses the following 16 symbols to represent numbers:

  • 0-9: representing decimal values 0 to 9
  • A-F: representing decimal values 10 to 15

For example, the hexadecimal number 1A represents the decimal value 26.

Necessity of Hexadecimal

Hexadecimal is particularly important in computer science. It is useful for representing binary-coded data more concisely. Converting long binary numbers to hexadecimal makes them much easier to understand and manage.

Hexadecimal Conversion

Converting Text to Hexadecimal

Converting text to hexadecimal involves transforming each character's Unicode value into its hexadecimal representation. For example, converting the string "Hello" to hexadecimal results in:

  • H: 48
  • e: 65
  • l: 6C
  • o: 6F

Therefore, "Hello" in hexadecimal becomes "48656C6C6F".

Use Cases of Hexadecimal

Computer Memory Addresses

Computer memory addresses are often represented in hexadecimal. For instance, the memory address 0x1A3F is equivalent to the decimal value 6719. Using hexadecimal makes memory addresses more concise and readable.

Color Codes

In web and graphic design, color codes are commonly represented in hexadecimal. For example, red is #FF0000, green is #00FF00, and blue is #0000FF. These hexadecimal color codes simplify the representation of RGB values.
