UPDATE!!!
Information Technology -CORRECTANSWER The technology used in creating,
maintaining, and making information accessible.
IT Professional Roles -CORRECTANSWER Administration and Support
System Administrator -CORRECTANSWER Maintains all aspects of the system
including hardware, software, and programming.
Network Administrator -CORRECTANSWER In charge of all aspects of the computer
network
Database Administrator -CORRECTANSWER Focuses on the design, development,
and support of database management systems (DBMSs).
Security Administrator -CORRECTANSWER Installs, configures, and administers
firewall security to protect systems and proactively work to stop intrusions.
Web Administrator -CORRECTANSWER Installs, configures, maintains, secures, and
troubleshoots web severs.
Support IT Professionals -CORRECTANSWER Help desk and training.
Information -CORRECTANSWER Processed data.
DIKW Hierarchy -CORRECTANSWER Defines the transition of data to information from
knowledge to wisdom. (Data Information Knowledge Wisdom)
Data in DIKW -CORRECTANSWER The 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 -CORRECTANSWER Having 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 -CORRECTANSWER 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.
Wisdom in DIKW -CORRECTANSWER Provides a social setting to knowledge; an
understanding of the "why". Can only come by having both knowledge and experience.
Information Systems -CORRECTANSWER 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.
Characteristics of Quality Data -CORRECTANSWER 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
IPOS -CORRECTANSWER The Input-Procession-Output-Storage Cycle
Input -CORRECTANSWER Raw data is entered by the user.
Processing -CORRECTANSWER Raw data is organized or structured for usefulness.
Output -CORRECTANSWER Information is output so user can see results.
Storage -CORRECTANSWER Processed information is stored for permanent record.
Computer System -CORRECTANSWER A collection of components that work together
to meet the needs of the user; typically categorized as either hardware, software,
networks, or users.
Hardware -CORRECTANSWER Physical components of a computer system which
include the system unit and its components and peripheral devices; tangible aspects of
the computer.
Software -CORRECTANSWER Computer programs that tell the computer what to do--
how to execute commands and process information
, Network -CORRECTANSWER A collection of computers and resources connected by
various media so that they can communicate with each other.
User -CORRECTANSWER Those who use a computer.
Software Categories -CORRECTANSWER Systems Software and Applications
Software
Evolution of Users -CORRECTANSWER 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.
Protocol -CORRECTANSWER Rules provided by which networks communicate with
each other.
TCP/IP -CORRECTANSWER Transmission Control Protocol/Internet Protocol. Most
commonly used protocol; is required of all computers that communicate over the
Internet.
Protocol Stack -CORRECTANSWER A collection of protocols. TCP/IP is an example.
Components of a Computer -CORRECTANSWER CPU, Memory and Storage,
Peripheral Devices
CPU -CORRECTANSWER Executes programs' instructions and commands various
components in the computer. Referred to as the "chip".
Memory -CORRECTANSWER Stores the programs being executed and the data they
are using.
I/O Subsystem -CORRECTANSWER All peripheral devices where long term storage
devices are used.
Bus -CORRECTANSWER Permits information to move between each component;
electrical channels that enable communication among the electronic components
System Unit -CORRECTANSWER 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.
Internal Components of the System Unit -CORRECTANSWER Case, Internal Bays,
Buses, Ports, Hard Drive, Motherboard, CPU, CPU Cooler, Memory Module (RAM),
Power Supply Unit (PSU), Expansion Slots/Cards
