   Also found in: Acronyms, Wikipedia 0.01 sec.
instruction set
The group of machine language instructions that a computer can follow, which may range from a handful to several hundred. It is a fundamental architectural component of a CPU and is either built into the CPU or into microcode, a layer between the instruction set and the circuitry. The instruction length is generally from one to four bytes long. See CISC, RISC, machine language, microcode and CPU.
instruction set [in′strək·shən ‚set]
(computer science)
Also known as instruction repertory.
The set of instructions which a computing or data-processing system is capable of performing.
The set of instructions which an automatic coding system assembles.

(architecture)instruction set - The collection of machine language instructions that a particular processor understands.

The term is almost synonymous with "instruction set architecture" since the instructions are fairly meaningless in isolation from the registers etc. that they manipulate.

The advantage of netbooks is that since they use Intel x86 architecture microprocessors, they can take software used on regular PCs, while smartbooks can only use software designed for or ported to RISC (reduced instruction set computer) processors, made by Arm Holdings.
Software has to be compiled for the chip architecture it runs on, whether x86 chips from Intel, AMD or Via Technologies, or RISC (reduced instruction set computer) chips such as those designed by Arm Holdings.
