CHAPTER 1Introduction to End User Computing
Prepared By : Suraya Alias
Historical Changes in Computer useDecade Primary Types and Uses of Computer System
1950s and 1960s
Early use of mainframe computers in large corporations Mainframe computers – large comp. system that processes huge volume of transactions, stores databases and act as a hub Data Processing Dept – department that handles/operates the company’s mainframe computer Batch processing – a collection of transactions (day, week, month) that were processed in a group Management Information System (MIS) Department – computer software that automates the preparation of reports for managers and employee
1970s First step to decentralization computing
1980s and 1990s
The growth of decentralized computing Causes : 1. Application backlog
2. More knowledge workers
3. Inexpensive microcomputers
4. Inexpensive productivity software
5. Development of user-friendly GUI
Historical Changes in Computer use
Decade Primary Types and Uses of Computer System
1990s and 2000s
The Era of Distributed and Network Computing Distributed Computing – an computing environment that determines the locations of the computer resources, such as network servers and mainframes Decentralized Systems – individual PCs on employees desk Data processing Dept has been renamed to Information System Department or IT Department
End user Classification
Environment – home or personal users, corporate or organizational users
Skill level – novice, unskilled, semiskilled, expert Principal Applications – Word, email, accounting Frequency of use – occasional, frequent, constant Features used – basic, intermediate, advanced Location – Internal, external
Internal users – users/workers in an organization External users - users outside an organization, such as
customers, software vendors, personal home users
Resources End Users need
1. Hardware 2. Peripherals 3. Hardware Upgrades and 4. Software and Software Upgrades 5. Supplies 6. Data Maintenance 7. Technical Support 8. Facilities, Administration, and Overhead
End users Application Software
1. Word Processing 2. Electronic Mail 3. Database Management 4. Graphics 5. Planning and Scheduling 6. Desktop Publishing 7. Educational Software and Computer Games 8. Mainframe Applications
Problems with End User Computing
1. Waste The use of money, time or resources that does not contribute
directly to user’s productivity2. Mistakes Careless end users with no proper training3. Computer Crime Employee that accessed company’s info4. Piracy Software theft that involves illegal copying, distribution or use5. Invasion of Privacy Unauthorized users that exploits personal information
Problems with End User Computing
6. Loss of Data Users that does not backup data
7. Computer Virus Computer programs with malicious intent that can destroy
information
8. Health Problems Carpal Tunnel Syndrome – severe hand, wrist pain due to
overstraining use of computer Ergonomics – a field that study how to design a better
workspace in terms of health, safety and productivity
