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