CHAPTER ONE: INTRODUCTION TO INFORMATION SYSTEMS
Learning objectives
1. Articulate why it is important to studying IS
2. Name and describe the components of a CBIS
3. Identify the characteristics of valuable information
4. Identify the basic types of business IS, their primary users and how they are used

Information Systems
• Information is a collection of facts
o Text
o Numbers
o Images Examples
o Audio clips
o Video clips
o Also known as data
• System: a set of elements or components that interact to accomplish goals
o Input process output
• Important because it is everywhere
o Day to day tasks o Economic activities
o Teaching o Social interactions
o Learning
Computer-based Information Systems
• A single set of hardware, software, databases, telecommunications, people, and
procedures that are configured to collect, manipulate, store, and process data into
information.
• Hardware: physical components
• Software: set of instructions that tell the hardware what to do
o Operating systems: control the operations of hardware
o Application software – supports the completion of tasks
• Database: collection of related information
• Telecommunication: supports communication between people and devices on a
network
• People: individuals that use and are affected by computer-based information
systems
• Procedure: supports communication between people and devices on a network
Valuable information
• Accessible • Secure • Relevant
• Complete timely • Simple
• Flexible • Accurate • Reliable
• Economical • Verifiable
