Instruction

An instruction is a form of communication information that is both ''command'' and explanation'' for how an action (philosophy), behavior, method, or task is to be begun, completed, conducted, or executed. == Computing == In computer science, an instruction typically refers to a single operation of a processor within a computer architecture. The types of instruction allowed are defined and determined within the particular platform's instruction set architecture (ISA), which also determines Processor_register sources and destination operands, and perhaps an immediate field. Machine instructions are written as binary codes, but each are commonly matched to human-readable Opcode, by which programming direct machine-level interfaces and APIs is made easier. The size, or "width" of an instruction depends on the architecture of the Platform (computing), but it is usually from 4 to 64 (typically, 4, 8, 16, 32, 40, 64) bits wide. The following is an example of a x86 instruction :SHL AX, 01 where SHL is called an Operator (programming), and AX, 01 are called operands, where AX is a register, 01 is a Variable#constant. The value in AX is shift left 01 time which is equivelent to double it in the instruction in this example. In abstracted high level language, an instruction may refer to part of a computer program in a programming language — see also Procedure. ==French law== In the context of France law (or inquisitorial systems based on France's), the ''instruction'' is the pre-trial phase of a criminal investigation that is led by a judge. More generally, it refers to phases of judicial or administrative proceedings where a request is investigated, and information pertaining to it is collected, before a final decision is made. ==Music== Instruction is the name of a rock band from New York City who features members of Errortype:11, Quicksand, Saetia and Garrison. ==See also== *Knowledge visualization
