Information Knowledge Wisdom) - ANSWERSDIKW Hierarchy
The input directly received by the user (or computer). It is generally not usable until it
has been converted into a relevant form. - ANSWERSData 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. - ANSWERSInformation 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. - ANSWERSKnowledge in DIKW
Provides a social setting to knowledge; an understanding of the "why". Can only come
by having both knowledge and experience. - ANSWERSWisdom in DIKW
,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. - ANSWERSInformation Systems
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 - ANSWERSCharacteristics of Quality Data
The Input-Procession-Output-Storage Cycle - ANSWERSIPOS
Raw data is entered by the user. - ANSWERSInput
Raw data is organized or structured for usefulness. - ANSWERSProcessing
Information is output so user can see results. - ANSWERSOutput
Processed information is stored for permanent record. - ANSWERSStorage
A collection of components that work together to meet the needs of the user; typically
categorized as either hardware, software, networks, or users. - ANSWERSComputer
System
Physical components of a computer system which include the system unit and its
components and peripheral devices; tangible aspects of the computer. -
ANSWERSHardware
Computer programs that tell the computer what to do--how to execute commands and
process information - ANSWERSSoftware
A collection of computers and resources connected by various media so that they can
communicate with each other. - ANSWERSNetwork
Those who use a computer. - ANSWERSUser
Systems Software and Applications Software - ANSWERSSoftware Categories
, 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. - ANSWERSEvolution of Users

Referred to as the "chip". - ANSWERSCPU
Stores the programs being executed and the data they are using. - ANSWERSMemory
All peripheral devices where long term storage devices are used. - ANSWERSI/O
Subsystem
Permits information to move between each component; electrical channels that enable
communication among the electronic components - ANSWERSBus
Critical 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. -
ANSWERSSystem Unit
Case, Internal Bays, Buses, Ports, Hard Drive, Motherboard, CPU, CPU Cooler,
Memory Module (RAM), Power Supply Unit (PSU), Expansion Slots/Cards -
ANSWERSInternal Components of the System Unit
Control 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 - ANSWERSParts of
the CPU
Controls the speed at which instructions are processed. - ANSWERSSystem Clock
Stands for Random Access Memory.
It temporarily stores data before it is processed and sent to your screen or printer.
