Definition
A base-16 system using 0 to 9 and A to F (A = 10 ... F = 15). One hex digit stands for exactly 4 bits, so it is a compact way to write binary.
Example: 2F in hex = 0010 1111 in binary = 47 in decimal.
Found in: syllabus, past SDD papers.
Where you'll use it in the test
Syllabus area: Y11 Programming Fundamentals.
Question types it can appear in
- Multiple choice: Pick the option that matches the definition or example.
