🧠 What Are Binary and Hexadecimal Systems?
Binary (Base-2)
- Composed of only 2 digits: 0 and 1
- Used internally by nearly all modern computers and digital systems
- Each binary digit is called a bit
Hexadecimal (Base-16)
- Uses 16 symbols: 0–9 and A–F
- Commonly used in computing for compact binary representation
- 1 hex digit = 4 binary digits (bits)

✏️ Conversion Formulas and Logic
🔹 Binary to Decimal
Each binary digit is multiplied by 2 raised to the power of its position (starting from the right).
Example: 1011 → Decimal
= 1×2³ + 0×2² + 1×2¹ + 1×2⁰
= 8 + 0 + 2 + 1 = 11
🔹 Decimal to Binary
Divide the number by 2 repeatedly and write down remainders in reverse order.
Example: 13 → Binary
13 ÷ 2 = 6 R1
6 ÷ 2 = 3 R0
3 ÷ 2 = 1 R1
1 ÷ 2 = 0 R1
Answer: 1101
🔹 Binary to Hex
Group binary digits in sets of four (from right) and convert to hex.
Example: 11010111 → Hex
Group: 1101 0111
1101 = D, 0111 = 7
Answer: D7
🔹 Hex to Binary
Convert each hex digit to a 4-bit binary equivalent.
Example: 9A → Binary
9 = 1001, A = 1010
Answer: 10011010
💻 Real-Life Examples
Example 1 – Memory Addressing
If a memory address is 0x1A3F
, what’s the binary form?
- 1 = 0001
- A = 1010
- 3 = 0011
- F = 1111
Binary: 0001101000111111
Example 2 – Binary to Decimal
Binary input: 11100101
= 1×2⁷ + 1×2⁶ + 1×2⁵ + 0×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰
= 128 + 64 + 32 + 0 + 0 + 4 + 0 + 1 = 229

⚠️ Common Mistakes to Avoid
- Confusing decimal numbers with binary strings.
- Forgetting to group binary in fours for hex conversion.
- Entering invalid characters (e.g., G in hex).
- Mixing up bit (binary digit) with byte (8 bits).
🧠 Tips for Understanding Base Conversions
- Binary is base-2, every digit represents a power of 2.
- Hex is base-16, every digit represents a power of 16.
- Hex is a shorthand for binary, 1 hex digit = 4 bits.
- Use leading zeroes for alignment when converting binary to hex.
