📌 What is Hexadecimal (HEX)?

The Hexadecimal system is a base-16 number system. It uses 16 symbols:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F

• Numbers 0–9 have their usual values.
• Letters A–F represent values 10–15.

👉 Example:

• HEX A = Decimal 10
• HEX F = Decimal 15

Hex is widely used in programming, memory addresses, colors in web design (#FFFFFF), and digital electronics.

📌 What is Binary?

The Binary system is a base-2 number system. It uses only two symbols:

0 and 1

👉 Example:

• Decimal 2 = Binary 10
• Decimal 5 = Binary 101

Binary is the language of computers because hardware circuits only recognize ON (1) and OFF (0) states.
