Binary to Decimal

**Introduction:**
Binary to Decimal conversion is a fundamental concept in computing, translating binary numbers (base-2) into decimal numbers (base-10). This process is crucial for understanding computer operations, as computers natively use binary.

**Demonstration:**
Consider the binary number `1011`. To convert it to decimal:
1. Write down the binary number: `1 0 1 1`.
2. Apply positional values, starting from the right (2^0): \(1 \times 2^3\), \(0 \times 2^2\), \(1 \times 2^1\), \(1 \times 2^0\).
3. Calculate each position: \(1 \times 8 = 8\), \(0 \times 4 = 0\), \(1 \times 2 = 2\), \(1 \times 1 = 1\).
4. Sum the results: \(8 + 0 + 2 + 1 = 11\).

**Usage:**
In programming, you can use built-in functions to convert binary to decimal. For example, in Python, use `int('1011', 2)`, and in JavaScript, use `parseInt('1011', 2)`. These functions take a binary string and return the corresponding decimal value.

**Conclusion:**
Understanding binary to decimal conversion is essential for anyone working with computers or studying computer science. It enhances your ability to work with low-level data, debug efficiently, and grasp the fundamentals of digital systems. Master this skill to elevate your technical proficiency and problem-solving capabilities.
