Chapter 2 Computer Systems Objectives and Overview Chapter 2 is the first of a trio of chapters devoted to the primary building blocks of information technology. Chapter 2 concentrates on computer systems, including both the hardware —the physical pieces of a computer system—and the software —the set of programs that controls the operations of the computer system. Chapter 3 covers telecommunications and networking, and Chapter 4 explores the data resource that is manipulated by the hardware, software, and telecommunications. These three chapters constitute the “hard-core” technology portion of this textbook. We believe that every information systems or information technology course using this textbook should incorporate these three chapters, covered in sequential order, unless the students already have strong technology backgrounds. The amount of time spent on these chapters will vary considerably, of course, depending upon the level and purpose of the course. Alternative approaches to using Chapter 2 are discussed in the “Teaching Suggestions” section below. Chapter 2 in the Seventh Edition is a brand new chapter, incorporating (in greatly reduced form) the material that was covered in Chapter 2, Computer Hardware, and Chapter 3, Computer Software, in the Sixth Edition of this book. The primary objective of Chapter 2 is to provide the student with a basic understanding of computer systems—both the hardware and the software. The goal of the chapter, simply stated, is to let the reader know what he or she needs to know about computer systems and no more . Managers need to understand the major ideas involved in computer systems, and they need to know the important terminology and concepts. Chapter 2 is aimed at satisfying this “need to know” in a straightforward, understandable way. It may be useful to view this chapter as consisting of five major sections—two of these are primarily devoted to computer hardware, two more are primarily devoted to computer software, and the fifth section is devoted to the information technology (IT) industry. The first major section provides an extended discussion of the underlying structure of computer systems , including the stored-program concept. This section will be largely review for those students who have significant practical computing experience (more than just word processing and spreadsheets) or those who have had previous courses in computer programming or information technology. The second major section describes the categories of computers in use today, including information about the hardware component of the information systems industry. This material will be new for most students and should provide a useful current perspective for everyone.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
