The reasoning behind these concepts was discussed in Chapter 2 but is worth summarizing here.

We are then prepared to examine the use of buses to interconnect system components. As background, the chapter begins with a brief examination of the basic components and their interface requirements. This chapter focuses on the basic structures used for computer component interconnection. In many cases, requirements for greater system power and fail-safe capabilities are being met by changing the design rather than merely increasing the speed and reliability of individual components. A grasp of the top-level structure and function offers insight into system bottlenecks, alternate pathways, the magnitude of system failures if a component fails, and the ease of adding performance enhancements. Equally important is its use to understand the increasingly complex issues of performance evaluation. This top-level view of structure and function is important because of its explanatory power in understanding the nature of a computer. Thus, at a top level, we can characterize a computer system by describing (1) the external behavior of each component, that is, the data and control signals that it exchanges with other components and (2) the interconnection structure and the controls required to manage the use of the interconnection structure. These components are interconnected in some fashion to achieve the basic function of the computer, which is to execute programs.
