1. Information Technology: The technology used in creating, maintaining, and making information acces-
sible.
2. IT Professional Roles: Administration and Support
3. System Administrator: Maintains all aspects of the system including hardware, software, and program-
ming.
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 management 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 Data: Relevance - the data being used must apply directly to the decision
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 computers, 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
33. CPU: Executes programs' instructions and commands various components in the computer. Referred to as the
"chip".
34. Memory: Stores the programs being executed and the data they are using.
35. I/O Subsystem: All peripheral devices where long term storage devices are used.
