The "Bitwise OR" operation is a fundamental concept in computer science and programming. It compares two binary numbers bit by bit and produces a new binary number. For each pair of bits, if at least one of the bits is 1, the resulting bit is set to 1; otherwise, it is set to 0. For example, if we apply the Bitwise OR to the binary numbers 1010 and 1100, the result will be 1110. This operation is commonly used in various applications, such as setting specific bits in a bitmask or combining flags in programming. The Bitwise OR is denoted by the symbol "|" in many programming languages, making it easy to implement in code. Understanding this operation is essential for tasks involving low-level data manipulation and optimization.
