Key Concepts

Bitwise AND

The bitwise AND operation compares corresponding bits of two bit strings and returns a 1 only when both bits are 1; otherwise, it returns 0. This operation is useful for masking bits, where only certain bits of a binary number are retained while others are cleared.

Bitwise XOR

The bitwise XOR (exclusive OR) operation compares corresponding bits of two bit strings and returns a 1 only if the bits are different, and a 0 if they are the same. This operation is widely used in error detection and correction schemes, as well as in various cryptographic algorithms.

Bitwise OR

The bitwise OR operation compares corresponding bits of two bit strings and returns a 1 in each position where at least one of the bits is 1, and a 0 only if both bits are 0. It is used to combine bit patterns and is integral to operations that require setting specific bits.

Bit Strings

A bit string is a sequence of bits (binary digits), typically representing data in binary form. They are used in computing for efficient data storage and manipulation, and serve as the foundation for bitwise operations, where corresponding bits from one string are operated on with those of another.

Bitwise Operations

Bitwise operations are actions performed on individual bits of binary numbers. They involve comparing corresponding bits from two bit strings to produce a new bit string. These operations are critical in low-level programming, cryptography, and data compression, providing a fast and efficient means to manipulate binary data.
