Adware
Programs that automatically display or download advertising to a computer.
Application Software
Software that is designed for the user to carry out a specific task.
Best Practice
A management process, technique, or method that is most effective at arriving at a desired
outcome or a better outcome than any other process, technique, or method.
Big Data
Data that is collected from all over the internet, including smartphone metadata, internet
usage records, social media activity, computer usage records, and countless other data
sources.
Bus Topology
A network topology sometimes called a linear bus, where each of a network's nodes is
connected to a common linear backbone that has two endpoints.
Business Analytics
Attempts to make connections between data so organizations can try to predict future
trends that may give them a competitive advantage.
Business Intelligence (BI)
Strategies and technologies used by enterprises for the data analysis of business
information.
Cache
A hardware or software component that stores data so that future requests for that data can
be served faster.
Campus Area Network (CAN)
A computer network that connects two or more LANs that are located on a campus.
Chief Information Officer (CIO)
A job title for the board-level head of an information technology department within a
business organization. The CIO's job is to make sure IT assets are in place to ensure a smooth
transition.
,Chief Information Security Officer (CISO)
The CISO is generally focused on the security of an organization's data and information,
making sure it is backed up, deciding who gets to see it and who does not, and so on.
Chief Security Officer (CSO)
A CSO is in charge of such things as the physical security and safety of employees, facilities,
and corporate assets and may have a law enforcement background.
Chief Technology Officers (CTO)
The CTO runs the organization's IT engineering group and serves as the company's top
technology architect.
Click Fraud
An internet fraud scheme that automatically passes a user to an advertiser, whether they
had any intention of visiting or not, in order to collect a per-click fee.
Clients
An end user's computer in a computer network.
Computer Network
Two or more computers connected together to communicate and share resources.
Cybersecurity
The convergence of technologies, sound practice, and processes designed to protect
networks and their devices, programs, and data from attack or unauthorized access.
Data Analysis
The application of statistics and logic techniques to define, illustrate, and evaluate data.
Data Management (DM)
The practices, architectural techniques, and tools for achieving consistent access to and
delivery of data across the spectrum of data subject areas and data structure types in the
enterprise.
Data Management Processes
The process of acquiring data, making sure the data are valid, and then storing and
processing the data into usable information for a business.
Data Mapping
Extra notes about the definition of a field, its data, and its use.
Data Mining
, The examination of huge sets of data to find patterns and connections and identify outliers
and hidden relationships.
Database Administrators (DBAs)
DBAs categorize data requirements and create the database entities and models that ensure
accurate and smooth-flowing information throughout a business.
Database Management System Software (DBMS)
An application software that is used to create a collection of related files that consist of
records of data separated by fields that can be queried to produce populations of
information.
Databases
Well-thought-out collections of computer files, the most important of which are called
tables.
Default-allow Firewall Rule
A rule that all traffic is allowed unless it has been specifically blocked.
Default-deny Firewall Rule
The only network connections that are permitted are the ones that have been explicitly
allowed.
Denial-of-service
An attempt to make a computer or any of its resources unavailable to its intended users.
Disk Storage
Nonvolatile, secondary storage on a physical device like a hard drive or optical disk with a
read/write apparatus.
Ethernet Card
Provides the computer with a unique 48-bit address called a MAC (media access control)
address. No two Ethernet cards have the same address.
Extract, Transform, and Load
Tools that are used to standardize data across systems and allow the data to be queried.
File Allocation Table (FAT)
A table of contents that directs the read/write arm of the hard drive to the location where
data exist and accesses the data upon the user's request.
Firewall
Specialized hardware and software that ensures that only authorized personnel can access
and use an organization's intranet.
