1. Information Technology The technology used in creating, maintaining, and making infor-
mation accessible.
2. IT Professional Roles Administration and Support
3. System Administrator Maintains all aspects of the system including hardware, software,
and programming.
4. Network Administrator In charge of all aspects of the computer network
5. Database Administrator Focuses on the design, development, and support of database
management systems (DBMSs).
6. Security Administrator Installs, configures, and administers firewall security to protect
systems and proactively work to stop intrusions.
7. Web Administrator Installs, configures, maintains, secures, and troubleshoots web
severs.
8. Support IT Professionals Help desk and training.
9. Information Processed data.
10. DIKW Hierarchy Defines the transition of data to information from knowledge to
wisdom. (Data Information Knowledge Wisdom)
11. Data in DIKW The input directly received by the user (or computer). It is generally
not usable until it has been converted into a relevant form.
12. Information in DIKW Having been inferred from data; one or more processes have been
applied to the data to transform it into a more useful form.
13. Knowledge in DIKW Information that has been put to use; information placed into a
context. Refined information such that the user of the knowledge

is able to call forth only relevant portions of information when
needed.
14. Wisdom in DIKW Provides a social setting to knowledge; an understanding of the
"why". Can only come by having both knowledge and experience.
15. Information Systems A collection of data and information used to support the manage-
ment of an organization. Also refers to the technical components
and human resources that enable the assembly, storage, and
processing of data and the delivery of information. This has existed
for a lot longer than computers.
16. Characteristics of Quality Relevance - the data being used must apply directly to the decision
Data being made
Timely - data must be efficient and must be provided in a timely
manner
Thorough - the data must be complete
Accurate - data should be captured only once, where possible and
should be captured as close to the point of activity as possible.
Reliable - data should reflect stable and consistent data collection
processes across collections points and over time
17. IPOS The Input-Procession-Output-Storage Cycle
18. Input Raw data is entered by the user.
19. Processing Raw data is organized or structured for usefulness.
20. Output Information is output so user can see results.

21. Storage Processed information is stored for permanent record.
22. Computer System A collection of components that work together to meet the needs
of the user; typically categorized as either hardware, software,
networks, or users.
23. Hardware Physical components of a computer system which include the
system unit and its components and peripheral devices; tangible
aspects of the computer.
24. Software Computer programs that tell the computer what to do--how to
execute commands and process information
25. Network A collection of computers and resources connected by various
media so that they can communicate with each other.
26. User Those who use a computer.
27. Software Categories Systems Software and Applications Software
28. Evolution of Users First users were the engineers who built and programmed com-
puters, then employees who had received specialized training
were users, and now today, anyone and everyone can be a user.
29. Protocol Rules provided by which networks communicate with each other.
30. TCP/IP Transmission Control Protocol/Internet Protocol. Most commonly
used protocol; is required of all computers that communicate over
the Internet.
31. Protocol Stack A collection of protocols. TCP/IP is an example.
32. Components of a Computer CPU, Memory and Storage, Peripheral Devices
