In computer architecture, 256-bit integers, memory addresses, or other data units are those that are 256 bits (32 octets) wide. Also, 256-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.There are currently no mainstream general-purpose processors built to operate on 256-bit integers or addresses, though a number of processors do operate on 256-bit data. (Wikipedia).

Bitwise Operators 2: The OR Operation
This computer science video describes the bitwise operation OR. It explains how the OR operation works with unsigned integers and how the OR operation can be used with a bitmask to manipulate the contents of a register containing bit flags. The equivalent OR operators are demonstrated i
