Policies Turn off your cell phone during lecture You are responsible for what is covered in class – even if you don ’ t show up Deficiency in attendance may lead to termination or relegation You are encouraged to help each other with your homework assignments – but you must turn in your own work If you are found to be cheating, you will fail at least the assignment / test and perhaps the entire class

4. Policies If you have any learning disabilities or special needs, please let me know in advance through email or personal meeting Quizzes are announced

5. Lecture # 1 Introducing Computer Systems

6. Information Technology  The branch of Engineering that deals with the use of Computers and Telecommunications to retrieve, store and transmit information  Any computer based tool that people use to work with information & support the information & information processing needs of an organization

7. Information Facts presented in a meaningful fashion. Technology A set of tools that enables us to work with information Hardware Input devices Output devices Telecommunication devices Storage devices Software Application software e.g.MS-office S/W, media software, business software System software e.g. operating system software, utility software Personal Computers Wireless Networks Satellites Cellular technology videoconferencing Internet

8. Information Technology Technical definition: “ The capability to electronically input, process, store, output, transmit, and receive data and information, including text, graphics, sound, and video, as well as the ability to control machines of all kinds electronically.”

9. Information Technology Technology  A set of tools that enables you to work more efficiently and effectively with information  Rationally speaking people and information are the most important resources within MIS, not Technology  Most of organizations need all three.

10. Understanding Your Computer Data The raw facts and figures that are processed into information Information Data that has been summarized or otherwise manipulated for use in decision making The purpose of a computer is to process data into information.

11. What is Data? Definition-1: “A collection of raw facts that describes a phenomenon” Examples – Current temperature – Price of a movie rental – Your age etc. Definition-2: “A message which source wants to communicate to the receiver” e.g Text, Voice, Image, movies, Music etc

12. What Is Information? Definition:  It has the particular meaning within a specific context  Every surprising/new thing is information  Reduction of redundancy in data For example if you are trying to decide what to wear, the current temperature is information because it is logical help to your decision.

13. Data Collection of raw unprocessed facts, figures, and symbols from various sources Information Data that is organized, meaningful, and useful What are data and information? Data Vs. Information

14. Information Facts presented in a meaningful fashion. Technology A set of tools that enables us to work with information Hardware Input devices Output devices Telecommunication devices Storage devices Software Application software e.g.MS-office S/W, media software, business software System software e.g. operating system software, utility software Personal Computers Wireless Networks Satellites Cellular technology videoconferencing Internet

15. Information Technology Technical definition: “ The capability to electronically input, process, store, output, transmit, and receive data and information, including text, graphics, sound, and video, as well as the ability to control machines of all kinds electronically.”

16. Dimension of Information Personal Time:- Access to info when you need it and information that describes the time period you are considering Location:- Access to information no matter where you are Form:- Information in a form that is most usable and understandable and information that is free of errors e.g Audio, Text, Video, Animation, Graph, Defective products etc

17. Dimension of Information Organizational Information Flows:- Up, Down, Horizontal, inward/outward {(Strategies, goals, directives), (Current State of the Organization), (Relation b/w Functional unites and work teams), (Customers, Suppliers, Partners)} What Information Describes:- Internal (specific operational aspects) External (Surrounding environment) Objective (Something known) Subjective (Something unknown)

18. Benefits of IT

19. Speed Computers can perform complex calculations, recall stored information, transmit information from one location to another in a split of a second. Consistency A computer can perform a task the same way every time.

20. Benefits of IT Precision Computers can detect minute differences that people can not see. In automobile manufacturing embedded computer system helps precise placement of a part. Reliability Reliability comes with speed, consistency and precision

21. What is a System? A system is… – A set of interrelated components – With a clearly defined boundary – Working together – To achieve a common set of objectives – By accepting inputs and producing outputs – In an organized transformation process

22. Basic Functions of a System Input – Capturing and assembling elements that enter the system to be processed Processing – Transformation process that converts input into output Output – Transferring transformed elements to their ultimate destination

23. What is an Information System? An organized combination of… – People – Hardware and software – Communication networks – Data resources – Policies and procedures This system… – Stores, retrieves, transforms, and disseminates information in an organization

24. What is an Information System? A system that collects, processes, stores, analyzes, and disseminates information. Collect Inputs Process And Transform Produce Outputs Store Data Instructions Calculations Reports

25. IS---Examples Online bill payment system at a bank A support website of a product Computer system used to process orders for a business

26. Management Information System (MIS) Technical definition: “ MIS deals with the planning for, development, management, and use of information technology tools to help people perform all tasks related to information processing and management.”

27. What Makes Information Useful? It is accurate – Free of errors It is complete – Includes everything needed It is flexible – Can be viewed in various ways It is reliable – Results are always consistent It is relevant – Applies to the issue under study It is timely – Available when needed It is verifiable – Basis for results can be traced It is accessible – All those who need the information can get to it It is secure – Free from contamination (accidental or deliberate)

28. What Should Business Professionals Know?

29. Measuring IT Success Efficiency – Minimize cost, time, and use of information resources Effectiveness – Support business strategies – Enable business processes – Enhance organizational structure and culture – Increase customer and business value

30. Developing IS Solutions

31. Components of an IS

32. Where Computers Are Used: Education Teaching and testing aid Learning by doing Computer-based instruction

33. Where Computers Are Used: Retailing Bar codes for pricing and inventory Shipping

34. Where Computers Are Used: Energy Locate oil, coal, natural gas, and uranium Monitor the power network Meter reading

35. Where Computers Are Used: Agriculture Billing Crop information Feed combinations Livestock breeding and performance

36. Where Computers Are Used: Health and Medicine Monitor patients Electronic imaging Diagnose illnesses Tele-health

37. Where Computers Are Used: Robotics Perform jobs that are dangerous for humans Factory work

38. IT In Support of Business  Credit Card, Debit Card, ATM Card  Bar Code Security Access  E-commerce  On-Line Conferences

39. IT In Support of Business Operational Excellence  Within the context of efficiency  Doing things right  In the least amount of time  At the least expense  With the fewest numbers of errors  Optimizing the use of resources
