Assessment
Information Technology - ANSWERThe technology used in creating, maintaining, and
making information accessible.
IT Professional Roles - ANSWERAdministration and Support
System Administrator - ANSWERMaintains all aspects of the system including
hardware, software, and programming.
Network Administrator - ANSWERIn charge of all aspects of the computer network
Database Administrator - ANSWERFocuses on the design, development, and support
of database management systems (DBMSs).
Security Administrator - ANSWERInstalls, configures, and administers firewall
security to protect systems and proactively work to stop intrusions.
Web Administrator - ANSWERInstalls, configures, maintains, secures, and
troubleshoots web severs.
Support IT Professionals - ANSWERHelp desk and training.
Information - ANSWERProcessed data.
DIKW Hierarchy - ANSWERDefines the transition of data to information from
knowledge to wisdom. (Data Information Knowledge Wisdom)
Data in DIKW - ANSWERThe input directly received by the user (or computer). It is
generally not usable until it has been converted into a relevant form.
Information in DIKW - ANSWERHaving been inferred from data; one or more
processes have been applied to the data to transform it into a more useful form.
Knowledge in DIKW - ANSWERInformation 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.
,Wisdom in DIKW - ANSWERProvides a social setting to knowledge; an understanding
of the "why". Can only come by having both knowledge and experience.
Information Systems - ANSWERA 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.
Characteristics of Quality Data - ANSWERRelevance - 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
IPOS - ANSWERThe Input-Procession-Output-Storage Cycle
Input - ANSWERRaw data is entered by the user.
Processing - ANSWERRaw data is organized or structured for usefulness.
Output - ANSWERInformation is output so user can see results.
Storage - ANSWERProcessed information is stored for permanent record.
Computer System - ANSWERA collection of components that work together to meet
the needs of the user; typically categorized as either hardware, software, networks,
or users.
Hardware - ANSWERPhysical components of a computer system which include the
system unit and its components and peripheral devices; tangible aspects of the
computer.
Software - ANSWERComputer programs that tell the computer what to do--how to
execute commands and process information
Network - ANSWERA collection of computers and resources connected by various
media so that they can communicate with each other.
User - ANSWERThose who use a computer.
, Software Categories - ANSWERSystems Software and Applications Software
Evolution of Users - ANSWERFirst 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.
Protocol - ANSWERRules provided by which networks communicate with each other.
TCP/IP - ANSWERTransmission Control Protocol/Internet Protocol. Most commonly
used protocol; is required of all computers that communicate over the Internet.
Protocol Stack - ANSWERA collection of protocols. TCP/IP is an example.
Components of a Computer - ANSWERCPU, Memory and Storage, Peripheral Devices
CPU - ANSWERExecutes programs' instructions and commands various components
in the computer. Referred to as the "chip".
Memory - ANSWERStores the programs being executed and the data they are using.
I/O Subsystem - ANSWERAll peripheral devices where long term storage devices are
used.
Bus - ANSWERPermits information to move between each component; electrical
channels that enable communication among the electronic components
System Unit - ANSWERCritical component of all computer based systems; consists of
most of the hardware the computer needs in order to run; comes in a variety of
shapes and sizes.
Internal Components of the System Unit - ANSWERCase, Internal Bays, Buses, Ports,
Hard Drive, Motherboard, CPU, CPU Cooler, Memory Module (RAM), Power Supply
Unit (PSU), Expansion Slots/Cards
Parts of the CPU - ANSWERControl Unit (CU) - retrieves the instructions and the raw
data that is input and coordinates or controls the sending of those instructions and
data to the ALU
Arithmetic Logic Unit (ALU) - does the actual processing of the data; completing
mathematical calculations and logical operations to process the data and converting
the input of the keyboard text entry to output displayed on the screen
System Clock - ANSWERControls the speed at which instructions are processed.
RAM - ANSWERStands for Random Access Memory.
It temporarily stores data before it is processed and sent to your screen or printer.
