IT is about technology which is consist of electronic device, computing technology and communication technology. While IS is about the usage of IT tools by group of people or staff in managing information such in organization.
Information technology is the technological components e.g. Radar in Battle of Britain.
Information system is the collection of technological components, users and data into systems designed to produce information to aid decision making
Information Systems (IS) – all components and resources necessary to deliver information and information processing functions to the organization
Information Technology (IT) – various hardware components necessary for the system to operate
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.
One is a system and one is a form of technology
Information system is father who bought mutton and information technology is mother who make mutton biryani
