1. Information Processing Lecture 1

2. Overview of Week 1 Introduction to the Module Course Materials and Methods The Elements of a Computer Some History Activities

3. Overview of the Programme: Content- Theory There are six ‘broad areas’ of theory History and Hardware Social Issues of IT Computer Architecture The CPU Systems Software File Handling

4. Overview of the Programme: Content- Practical There are three ‘hands-on’ topics: Word-Processing Presentation Graphics Web Design

5. Assessment Formative Tasks Summative Assignments –Presentation 1 (5%) –Report (20%) –Web Assignment (20%) –Presentation 2 (15%) Examination (40%)

6. Overview of the Programme: Content- Theory and Practice It is an underlying philosophy of the course delivery that we integrate both theory and practice in a meaningful manner. For example: the focus for your Word- Processing is an assignment on the History of Computing This means that you are hitting both objectives simultaneously

7. Course Material and Set texts It is vitally important that as well as the lectures you read: The IMC Booklets The Set Text: –Dick, D., 2001: “The P.C. Support Handbook”, : Dumbreck Publishing, ISBN 0-9541711-0-1 Other Sources –Library, including: books, Periodicals –CD ROMs –Trade Journals –Newspapers –Internet

8. Teaching and Learning Lecture-Presentations on key topics. Practical ‘hands-on’ workshops introducing particular items of software. Directed reading from the set text Library/Internet research Directed tasks Discussions Workshop tutorial sessions Assignments

9. How much work am I supposed to do? Each week you should be putting in around 12 –15 hours work. This consists of: –One 2-hour lecture –One 1-hour practical –Around 6 hours on directed tasks –Around 3-6 hours of reading and personal study

10. Objectives For Week 1 After studying this week’s work, you should: Have begun to assimilate some of the terminology of computer systems and their architecture Have understood the different functions of the elements of a computer system Know some of the history of the how computer technology was developed Have begun to collaborate with others, in order to research and present a topic.

11. Some Definitions A computer –Stores data –Manipulates data –Retrieves data –Communicates data Two aspects to data –Information –Instructions

12. Components 1 Processor Keyboard Scanner Mouse Etc. Main Memory Magnetic Disk Optical Disk Etc. Monitor Printer Microfiche Etc..

13. Inside the Processor ALU (Arithmetic and Logical Unit) Control Unit (CU) Interface Unit

14. Components 2 Hardware Peripheral devices Software

15. Main Types of Computer Micro- Mini- Mainframe Super-

16. History of Computing A study of the history of the way that computers have developed helps us to understand: –Hardware, its structure, functions and terminology, –Software – its principles, languages and structures. We can also grasp some of the potential and some of the limitations of computers.

17. A Potted History: Some names and Dates Pascal (1642) calculating machine Jacquard (1801) Jacquard Loom Babbage (1800s) analytical engine Aiken (1937) Mark I computer Atanasoff, Berry (1939) ABC computer Mauchly, Echert (1940’s) ENIAC Von Neumann (1945) Von Neumann architecture

18. Task 1 for next week Create a Group Presentation on one topic within the History of Computing. Maximum four slides only For visuals you may use acetates, posters, PowerPoint (or other Graphics) – or nothing. Brief: –Research the History of Computing using the internet and three different textual sources. –Select one aspect (this could be a single development, or a period in history or a particular thread of development such as ‘operating systems’.) –Create a presentation of about 10 minutes to deliver to the class for next week.

19. Task 2 for next week Obtain a copy of the set text. Read the chapter on peripherals (p. 294 ), and make some notes. Prepare yourself to participate in a lecture-discussion on these.

20. What have we covered? Elements of a Computer Terminology Peripherals History of Computing
