Key Points Review – Chapter 1
1. Explain what an information system is, contrasting its data, technology, people, and
Information systems are combinations of hardware, software, and telecommunications networks
that people build and use to collect, create, and distribute useful data, typically in organizational
settings. When data are organized in a way that is useful to people, these data are defined as
information. The term “information systems” is also used to represent the field in which people
develop, use, manage, and study computer-based information systems in organizations. The field
of IS is huge, diverse, and growing and encompasses many different people, purposes, systems,
and technologies. The technology part of information systems is the hardware, software, and
telecommunications networks. The people who build, manage, use, and study information
systems make up the people component. They included systems analysts, systems programmers,
information systems professors, and many others. Finally, information systems typically reside
and are used within organizations, so they are said to have an organizational component.
Together, these four aspects form an information system.
