Information Technology The technology used in creating, maintaining, and making
information accessible.
IT Professional Roles Administration and Support
Maintains all aspects of the system
including
System Administrator hardware, software, and programming.
Network Administrator In charge of all aspects of the computer network
Database Administrator Focuses on the design, development, and support of database
management systems (DBMSs).
Security Administrator Installs, configures, and administers firewall security to
protect systems and proactively work to stop intrusions.
Web Administrator Installs, configures, maintains, secures, and troubleshoots web
severs.
Support IT Professionals Help desk and training.
Information Processed data.
DIKW Hierarchy Defines the transition of data to information to knowledge to
wisdom. (Data Information Knowledge
Wisdom)
The input directly received by the user (or computer). It is
Data in DIKW generally not usable until it has been converted into a
relevant form.
,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.
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.
Wisdom in DIKW Provides a social setting to knowledge; an understanding of
the "why". Can only come by having both knowledge and
experience.
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.
Characteristics of Quality Relevance - the data being used must apply directly to the
Data 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 The Input-Procession-Output-Storage Cycle
Input Raw data is entered by the user.
Processing Raw data is organized or structured for usefulness.
, Output Information is output so user can see results.
Storage Processed information is stored for permanent record.
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.
Hardware Physical components of a computer system which include
the system unit and its components and peripheral
devices; tangible aspects of the computer.
Software Computer programs that tell the computer what to do--
how to execute commands and process information
Network A collection of computers and resources connected by
various media so that they can communicate with each
other.
User Those who use a computer.
Software Categories Systems Software and Applications Software
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.
Protocol Rules provided by which networks communicate with each
other.
TCP/IP Transmission Control Protocol/Internet Protocol. Most
commonly used protocol; is required of all computers
that communicate over the Internet.
Protocol Stack A collection of protocols. TCP/IP is an example.
Components of a CPU, Memory and Storage, Peripheral Devices
