**Hexadecimal**

Hexadecimal (or hex) is a system with base 16. Each nibble (a group of 4 bits) can be represented with 1 digit in hexadecimal system. It is very convenient to write in numbers in hex when compared to a binary system. It is helpful for programmers coding in low-level languages. Instead of 4 bits, it is enough if they type a single character.

This A Level Computer Science module introduces hexadecimal to your students, explaining:

- Hexadecimal numbers and its representation
- How to convert binary and denary numbers to their hexadecimal equivalents and vice versa?
- What are the applications of the hexadecimal number system?
