Chapter 2 an introduction to system concepts and systems architecture. A system is a collection of components linked together and organized in such a way as to be recognizable as a single unit. Linked components of a system also define the boundary for the system. The environment is anything outside of the system. The division of a system or subsystem into its components and linkages is called decomposition. Components may be irreducible or may be subsystems. The fundamental properties, and the patterns of relationships, connections, constraints, and linkage among the components and between the system and its environment are known collectively as the architecture of the system. Abstractions represents the real system but are not actually real system (the solar system does not conveniently fit inside a computer) The top-down approach allows us to focus on the specific areas of interest without the distractions of details that are irrele(cid:448)a(cid:374)t for the le(cid:448)el that (cid:449)e"re (cid:271)uyi(cid:374)g.
