1) Define Information Technology. Describe various types of information systems. Is Information Technology as vital to modern global business as money? Why or why not? Discuss some trends in IT development. Ans: In order to define Information Technology, let me define the term information first. By the term "information" we mean data that has been shaped into meaningful form that is useful to human beings. Data, in contrast, are streams of raw facts representing events occurring in the organization or physical environment before it has been organized and arranged into a form that people can understand & use. (Put diagram similar to the one in Laudon page 17 figure 1-3 and explain the example). .The technology plays the role of delivering timely & error free information to all the required recipients who are users of this information. In the context of a business firm technology consists of all the hardware and software that a firm needs to use in order to achieve its business objectives. This includes not only computer machines, disk drives and handheld mobile devices but also software, such as windows or Linux operating systems, the microsoft desktop productivity suite and many thousands of computer programs found in a typically large business firm. IT has become a major facilitator of business activities in the world today. IT is also a catalyst of fundamental changes in the strategic structure and management of operations.

Such systems are abundant in an organization, are inexpensive and have fairly standard capabilities. 2) Transaction Processing Systems In any Business there are basic routine tasks such as flow of raw material, sale of finished item, raising an invoice, payroll etc. to be performed in the context of various functions of the organization. A system which is used to monitor, collect, store, process & disseminate the basic business transactions in an organization is know as TPS (Transaction Processing System). The principal purpose of systems at this level is to answer routine questions and to track flow of transactions through the organization. How many parts are in the inventory? What happened to Mr

X's payment? to answer these kinds of questions, information generally must be easily available, current & accurate. Examples of TPS are, in a retail store at the point of sale when sale of a particular item is made, a transaction is generated which reduces the item in the inventory and increases the company's revenue by the amount of collected cash.
