Question :
(TCO A) What is the difference between information technology and information systems? Describe some of the functions of information systems.

Student Answer: Information technology also referred to as IT consists of all the hardware that a firm needs to attain its business goals. IT can be viewed as a way of implementation and management of computer information systems. Information systems on the other hand are a bit more challenging and complex in comparison to IT. Information systems are a set of interrelated components responsible for collecting, storing and distributing information that directly impacts decision-making and control within an organization. An information system helps employees analyze problems, helps create new products, supports decision-making and control in an organization, and also helps employees visualize complex subjects.
