  2. Course Objectives and Topics • At the end of this course students should be able discuss: • The major elements that make up the information system of a company (e.g. hardware, network, systems and application software) • IT issues and solutions related security, privacy and ethics • The steps involved in computer program development • Have the hands-on skills needed to: • Define and develop a basic web site • Work with Excel and Access to develop business useful information systems • Integrate the Microsoft Office products to create reports and presentations

  3. Course Methodology • The course will consist of: • Lectures, Tours and Labs • Reading of reference material • One project • Exams (5 exams, one can be dropped/missed, no final) • A fictional company, Wild Horse Productions, will be used as an example throughout the course • D2L will be used for lecture material, reference material, assignments, work submission, grades and news • Lab will be in KOM 350 (Monday and Friday) and 252 (Wednesday) • It is highly encouraged that you to bring a USB thumb drive to all Labs (2GB is more than adequate) Course material can be purchased from any Lab Assistant – full set $10 Order by 1/20 receive by 1/23

  10. Information Systems Flow • Raw input • Stored in distinct files (when stored) • Factors: Accuracy, timeliness Data • Organization of data more usable for processing • Contains the context/relationships for the data • Factors: Usability, integrity Database • Transformation of data base contents to support the functional needs of the entity • Factors: Functionality, accuracy Processing • Results of the processing • Factors: Timeliness, accuracy Information • User access to information • Factors: Timeliness, usability Presentation

  11. The Hardware Components of a Computer A computer contains many electric, electronic, and mechanical components. • System Unit – Where data analyzes, manipulates and otherwise transforms data • Input Device – A means of entering data into a computer system – from a human or other source • Output Device – A means of presenting data processed by a computer system – to a human or other consumer of the information • Storage Devices – Components that provide temporary or permanent retention of the data for future use

  12. Categories of Computers Computers can be classified based on: • Intended use • Capacity Basic Classes are: • Embedded • Other specialize computers – e.g. Game Consoles • Personal Computers • Servers and other shared use computers

  13. Personal Computers • A Personal Computer is a self-contained computing system, designed to address the needs of a single user • Form factors include desktop, netbook, netbook, tablet, mobile/handheld Apple versus PC, that is the question?

  14. Servers • Servers provide shared processing and access to shared storage • Servers are classified by: • Capacity • Resilience • Specialized capabilities

  15. A Network consists of the equipment and transmission media used to link together computers – locally or over wide distances Networks

  16. The Internet The Internetis a network of networks.

  17. Computer Software • Programs, also called Software, tell the computer what tasks to perform and how to perform them • Software programs are developed by programmers to meet specific functions • Software can be placed in two major categories: • Systems Software – Programs to manage computer systems resources • Application Software – Programs that provide services to users

  18. Computer Software – Systems Software Systems Software perform the basic functions needed to run a computer system • Operating system • Resource allocation • Basic data/file management • Communications • User interface • Other systems software is needed for computer system to effectively operate, examples include: • Backup or restore data • Exchange data between computers • Monitor systems health • Software that translates program specifications written by developers into instructions executable by a computer (compilers) • Data base management systems

  19. Computer Software – Applications Software • Application Software perform functions that are designed to provide value to businesses and users. • There are various types of applications software, including: • Office automation/collaboration • Multi-media • Business support • General (e.g. Human Resources Information System) • Industry specific (e.g. Point of Sale, process control) • Application Software rely on the Systems Software for basic services (e.g. access to files, communications) • Application software can be delivered in multiple ways: • One-on-one with a user • On a network via a server – non-web or web enabled

  20. The Three Laws The Three Laws of Robotics* are as follows: • A robot may not injure a human being or, through inaction, allow a human being to come to harm. • A robot must obey any orders given to it by human beings, except where such orders would conflict with the First Law. • A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. Isaac Asimov How are we doing regarding our use of computers? What can we do as individuals to protect our privacy? Do we have to give up our privacy to participate in social media?
