This topic is discussed about Information System (IS) function, IS components, IS Activities, IS Business Environment, and IS Evolution. Information system (IS) combines five components. What is an Information System (IS) function? IS can be function as a major source of information and it will support for the decision making. IS are important contributor to operational efficiency, employee productivity, morale, customer service and satisfaction. In sum, it is a key component of today’s networked business.
It is about the hardware (physical computer equipment, machines and media) and software (programs and procedures) which are the main tools for the system to run. It is also about the data resources (data and knowledge bases), communication networks (communications media and network support) and people (for example: users, programmers).
I get more on IS activities which is Input of data resources (data entry activities), Processing of data into information (calculations, comparisons sorting and so on), Output of information products (messages, reports, graphic images, forms), Storage of data resources (data elements and databases) and lastly is Control of system performance (monitoring and evaluating feedback).
