System concepts – an Introduction

System concepts underlie the field of information systems. Understanding system concepts will help in understanding many other concepts in the technology, applications, development, and management of information systems. System concepts help to understand

Technology

That computer networks are systems of information processing components that uses a variety of hardware, software, data and telecommunication technologies.

Applications

That electronic business and commerce involves interconnected business information systems.

Development

That developing ways to use information technology in business includes designing the basic components of information systems.

Management

That managing information technology emphasizes the quality, strategic business value, and security of an organization’s information systems.

A system is a group of interrelated components working together toward a common goal by accepting inputs and producing outputs in an organized transformation process. A system (sometimes called a dynamic system) has three basic interacting components or functions.

These include

Input involves capturing and assembling elements that enter the system to be processed.

Processing involves transformation processes that convert input into output.

Output involves transferring elements that have been produced by a transformation process to their ultimate destination.
