This document provides an overview of information systems. It defines an information system as any combination of information technology and people's activities that support operations, management, and decision making. An information system collects, processes, stores, analyzes and disseminates information for a specific purpose. It discusses the key components of an information system including interfaces, sub-systems, boundaries, and environment. It also categorizes different types of information systems such as transaction processing systems, management information systems, decision support systems, and executive information systems.

system includes inputs (data, instructions) and
outputs (reports, calculations). It processes the inputs
by using technology such as PCs and produces
outputs that are sent to users or to other systems via
electronic networks and a feedback mechanism
that controls the operation.
