What does it mean to say we are in a “post-PC world”? Submitted by IncludeHelp, on March 21, 2018 . The study of information systems goes far beyond understanding some technologies. Let’s take a look at each of these. Components of information systems The main components of information systems are computer hardware and software , telecommunications, databases … It has always been the assumption that the implementation of information systems will, in and of itself, bring a business competitive advantage. Others add a sixth element, communications, to the list. The first three are technology. By themselves, pieces of data are not really very useful. Companies began connecting their internal networks to the Internet in order to allow communication between their employees and employees at other companies. For example, when you use an Internet browser, there is a process running for that browser program. Software will be explored more thoroughly in chapter 3. In information system inputs are data that are going to be transformed. Software: These are the programs used to organize, process and analyze data. Morley and Parker (2010) define information system as a discipline that is formed from elements of business and computer science and is developing to form a separate area of scientific study. (2008) “Medical Informatics: Practical Guide for the Healthcare Professional” Lulu, Morley, D. & Parker, C. (2010) “Understanding Computers: Today and Tomorrow, Comprehensive” Cengage Learning, Wager, K.A., Lee, F.W & Glaser, J.P. (2009) “Health Care Information Systems: A Practical Approach for Health Care Management”. “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.”, “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.”, “Information systems are interrelated components working together to collect, process, store, and disseminate information to support decision making, coordination, control, analysis, and viualization in an organization.”. People consist of devi… Information systems hardware is the part of an information system you can touch – the physical components of the technology. In information system inputs are data that are going to be transformed. The process component of an information system transforms input into an output. The process management component is tasked with managing the many processes that are running on the operating system. I generally get answers such as “computers,” “databases,” or “Excel.” These are good answers, but definitely incomplete ones. Output is … This drove prices down and spurred innovation. In summary, these five components together make up the five component framework, which are the five fundamental components of an information system. Many students understand that an information system has something to do with databases or spreadsheets. When programmers create software programs, what they are really doing is simply typing out lists of instructions that tell the hardware what to do. Each of these will get its own chapter and a much lengthier discussion, but we will take a moment here to introduce them so we can get a full understanding of what an information system is. Like software, data is also intangible. This evolved into software applications for communicating, with the first real popular use of electronic mail appearing at this time. Registered trademark of Wal-Mart Stores, Inc. Walmart is the world’s largest retailer, earning $15.2 billion on sales of $443.9 billion in the fiscal year that ended on January 31, 2012.
