the opcode is a pointless set of numbers computers use to fuck each other.

In [[computer science]], an '''opcode''' ('''Op'''eration '''Code''') is the portion of a [[machine language]] [[instruction (computer science)|instruction]] that specifies the operation to be performed. Their specification and format will be laid out in the [[instruction set architecture]] (ISA) of the [[computer hardware]] component in question—normally a [[central processing unit|CPU]], but possibly a more specialized unit. A complete machine language instruction contains an opcode and, optionally, the specification of one or more [[operand]]s—what data the operation should act upon. Some operations have ''implicit'' operands, or indeed none. Some ISAs have instructions with defined fields for opcodes and operands, while others (e.g. the [[Intel x86]] architecture) have a more complicated and ad-hoc structure.
