Contrast IS and IT:
What is the difference between Information Systems and Information Technology? In: Computer Terminology, Technology, Information Technology[Edit categories] Answer:
Information Systems is a large umbrella referring to systems designed to create, store, manipulate, or disseminate information. Example of an information system is a pencil and a piece of paper. The two objects themselves are just tools, but together they create a system for writing (information). The term Information systems has been around a lot longer than the computer, or the term information technology. These days the two are sometimes thought to be synonymous, but that, in most cases is a misconception.
Information technology falls under the information systems umbrella, but has nothing to do with systems per say. IT deals with the technology involved in the systems themselves, e.g. an information system like wiki.answers.com contains many information technologies. Servers, server operating systems, web-server software (IIS, Apache, et al), and code written for the web-server software (PHP, C#, VB, PERL, Ruby, et al). Even your computer and browser make up part of this information system. Like the pencil and paper example, each one of the mentioned parts of this information system in itself is an information technology.
That being said, most people in the profession no longer make a distinction. Moreover, companies call their IS/IT department a wide range of titles based on more on culture and tradition than anything else.
Assist With Business Processes
Information systems aid businesses in developing a larger number of value added-systems in the company. For example, a company can integrate information systems with the manufacturing cycle to ensure that the output it produces complies with the requirements of the various quality management standards. Adoption of information systems simplifies business processes and removes unnecessary activities. Information systems add controls to employee processes, ensuring that only users with the applicable rights can perform certain tasks. Further, information systems eliminate repetitive tasks and increase accuracy, allowing employees to concentrate on more high-level functions. Information systems can also lead to better project planning and implementation through effective monitoring and comparison against established criteria.
