Understanding Binary Number Systems
Binary is the foundation of all digital computing, using only two digits (0 and 1) to represent any value. Each binary digit (bit) represents a power of two, with positions increasing from right to left. This simple yet powerful system enables computers to process complex calculations, store vast amounts of data, and execute sophisticated algorithms. Understanding binary operations is essential for low-level programming, digital circuit design, and computer architecture.

Two's Complement Signed Representation
Two's complement is the standard method for representing signed integers in modern computers. It elegantly solves the problem of negative number representation while allowing the same hardware to perform both addition and subtraction. The most significant bit serves as the sign bit (0 for positive, 1 for negative), and negative numbers are formed by inverting all bits and adding one. This representation eliminates the dual zero problem and simplifies arithmetic circuit design. Understanding two's complement is essential for overflow detection and signed arithmetic operations.

Bit Shifts and Rotations
Bit shifts and rotations are fundamental operations for efficient multiplication, division, and data manipulation. Shifts move bits left or right, with new bits filled according to the shift type (logical, arithmetic, or circular). Rotations preserve all bits by wrapping them around. These operations are essential for cryptographic algorithms, data compression, and performance optimization. Learn how shifts interact with carry flags and affect signed values.
⬅️ Left Shifts
- Logical: Fill with zeros from right
- Multiplication: Each shift multiplies by 2
- Overflow: Lost bits set carry flag
➡️ Right Shifts
- Logical: Fill with zeros from left
- Arithmetic: Preserve sign bit
- Division: Each shift divides by 2
🔄 Rotations
- Circular: Bits wrap around
- No Loss: All bits preserved
- Crypto: Used in ciphers
