In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts.[1] It can sometimes be a high-level description that ignores details of the implementation.[2] At a more detailed level, the description may include the instruction set architecture design, microarchitecture design, logic design, and implementation.[3]

Architecture describes the internal organization of a computer in an abstract way; that is, it defines the capabilities of the computer and its programming model. You can have two computers that have been constructed in different ways with different technologies but with the same architecture.
