3. END-USER COMPUTING Chapter 1:

4. Computer  An electronic device which is capable of receiving data in a particular form and of performing a sequence of operations in accordance with a predetermined but variable set of procedural program to produce a result in the form of information.  Machine that processes facts and figure to produce information  Help people organize and save their thoughts

5. Historical Changes in Computer Technology The 1950s and 1960s: Early Mainframe Computers Highly Centralized Very Large Powerful Computer Systems Located at a central site in the organization Programmed and operated by computer professionals in the Data processing (DP) department - The division that programs and operates the organization’s mainframe computer system.

6. Historical Changes in Computer Technology The 1950s and 1960s: Early Mainframe Computers Use primarily to automate Transaction process and as MIS -Use of computers to input large volume of business activities and data processing. MIS refers to computer software that automates the preparation of reports for managers and employees. Data for input to a mainframe had to be delivered physically.

7. The 1950s and 1960s: Early Mainframe Computers

9. Historical Changes in Computer Technology The 1970s: The First Steps Toward Decentralized Computing Decentralized computers Terminal: A keyboard and a display screen that are connected to a mainframe computer by pair of wires were used by employees to enter or access information. Display only text Too expensive

10. The 1970s: The First Steps Toward Decentralized Computing

11. Historical Changes in Computer Technology The 1970s: The First Steps Toward Decentralized Computing Another step towards decentralized computing was the introduction of minicomputers during 1970’s. Smaller computers Less powerful than a mainframe Much less expensive

12. Historical Changes in Computer Technology The 1980s and 1990s: The Growth of Decentralized Computing The backlog in requests for new mainframe applications An increase in the number of knowledge workers The availability of inexpensive Microcomputers - Complete computer built on small scale with a microprocessor as the central processing unit. The availability of inexpensive productivity software - Visi-Calc, Lotus, Dbase etc The development of user-friendly Graphical user interfaces -Screen images that enable users to access the program features and functions by making the program much easier to use.

13. The 1980s and 1990s: The Growth of Decentralized Computing

14. Historical Changes in Computer Technology The Late 1990s and 2000s: The Era of Distributed and Network Computing Distributed Computing refers to environment in which the needs of the organization determine the location of its computer resources. Requires a network technology to link central systems and personal computers

15. Timeline of computer decentralization

16. End-user Computing End-user computing refers to the every day use of computers for both business and personal use. End-user is a person who knows how to use a computer and communication technology to organize data, stimulate new ideas, solve problems and communicate the results to others. They employ a different mix of computer skills, equipment, programs and data
