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