Principles of Information Systems, Ninth Edition 3-2 Overview In this chapter, we concentrate on the hardware component of a CBIS. Hardware consists of any machinery (most of which uses digital circuits) that assists in the input, processing, storage, and output activities of an information system. The overriding consideration in making hardware decisions in a business should be how hardware can be used to support the objectives of the information system and the goals of the organization. Principles and Objectives Principles Learning Objectives Computer hardware must be carefully selected to meet the evolving needs of the organization and its supporting information systems. Describe the role of the central processing unit and main memory. State the advantages of multiprocessing and parallel computing systems, and provide examples of the types of problems they address. Describe the access methods, capacity, and portability of various secondary storage devices. Identify and discuss the speed, functionality, and importance of various input and output devices. Identify the characteristics of and discuss the usage of various classes of single-user and multiuser computer systems. The computer hardware industry is rapidly changing and highly competitive, creating an environment ripe for technological breakthroughs. Describe Moore’s Law and discuss its implications for future computer hardware developments. Give an example of recent innovations in computer CPU chips, memory devices, and input/output devices.
