This document defines information systems and describes their key components. It provides several definitions of information systems that focus on the technological components (hardware, software, data) that make up information systems and their role in supporting organizational processes and decision-making. The document outlines the five core components of information systems: hardware, software, data, people, and processes. It provides a brief description of each component, emphasizing that while technology is important, people and processes are what truly define information systems.

- 2. Information System What you people think about Information System? 1. Computers 2. Databases 3. Excel …. Note: These are good answers, but definitely incomplete ones. The study of information systems goes far beyond understanding some technologies. 4/3/2020 RAM K PALIWAL - MNAGEMENT INFORMATION SYSTEM BASICS - UNIT 1 2
- 3. Information System Definition: According to different Textbook- “Information systems (IS) is the study of complementary networks of hardware and software that people and organizations use to collect, filter, process, create, and distribute data.”1 “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.”2 4/3/2020 RAM K PALIWAL - MNAGEMENT INFORMATION SYSTEM BASICS - UNIT 1 3
- 4. Information System “Information systems are interrelated components working together to collect, process, store, and disseminate information to support decision making, coordination, control, analysis, and visualization in an organization.”3 Note: As you can see, these definitions focus on two different ways of describing information systems: ◦ The components that make up an information system ◦ The role that those components play in an organization. 4/3/2020 RAM K PALIWAL - MNAGEMENT INFORMATION SYSTEM BASICS - UNIT 1 4
- 5. Information System Components information systems are made up of five components: ◦Hardware ◦Software ◦Data ◦People ◦Process Note: The first three, fitting under the category technology But the last two, people and process, are really what separate the idea of information systems from more technical fields, such as computer science. 4/3/2020 RAM K PALIWAL - MNAGEMENT INFORMATION SYSTEM BASICS - UNIT 1 5
- 6. Information System Components Hardware Information systems hardware is the part of an information system you can touch – the physical components of the technology. Computers, keyboards, disk drives, iPads, and flash drives are all examples of information systems hardware. Software Software is a set of instructions that tells the hardware what to do. Software is not tangible – it cannot be touched. When programmers create software programs, what they are really doing is simply typing out lists of instructions that tell the hardware what to do. Basically two types of Software, ◦ System Software ◦ Application Software 4/3/2020 RAM K PALIWAL - MNAGEMENT INFORMATION SYSTEM BASICS - UNIT 1 6
- 7. Information System Components Data Data as a collection of facts. For example, your street address, the city you live in, and your phone number are all pieces of data. Like software, data is also intangible. By themselves, pieces of data are not really very useful. But aggregated, indexed, and organized together into a database, data can become a powerful tool for businesses. Note: Organizations collect all kinds of data and use it to make decisions. These decisions can then be analyzed as to their effectiveness and the organization can be improved. 4/3/2020 RAM K PALIWAL - MNAGEMENT INFORMATION SYSTEM BASICS - UNIT 1 7
- 8. Information System Components People A focus on the people involved in information systems is the next step. From the front-line help-desk workers, to systems analysts, to programmers, all the way up to the chief information officer (CIO), the people involved with information systems are an essential element that must not be overlooked. Process The last component of information systems is process. A process is a series of steps undertaken to achieve a desired outcome or goal. Information systems are becoming more and more integrated with organizational processes, bringing more productivity and better control to those processes. 4/3/2020 RAM K PALIWAL - MNAGEMENT INFORMATION SYSTEM BASICS - UNIT 1 8
Editor's Notes
- #9: Process The last component of information systems is process. A process is a series of steps undertaken to achieve a desired outcome or goal. Information systems are becoming more and more integrated with organizational processes, bringing more productivity and better control to those processes. But simply automating activities using technology is not enough – businesses looking to effectively utilize information systems do more. Using technology to manage and improve processes, both within a company and externally with suppliers and customers, is the ultimate goal. Technology buzzwords such as “business process reengineering,” “business process management,” and “enterprise resource planning” all have to do with the continued improvement of these business procedures and the integration of technology with them. Businesses hoping to gain an advantage over their competitors are highly focused on this component of information systems.
