Big data analytics is the often complex process of examining large and varied data sets, or big data, to uncover information -- such as hidden patterns, unknown correlations, market trends and customer preferences -- that can help organizations make informed business decisions.

Unsupervised learning refers to the use of artificial intelligence (AI) algorithms to identify patterns in data sets containing data points that are neither classified nor labeled.

Supervised learning is an approach to creating artificial intelligence, where the program is given labeled input data and the expected output results.

Systems thinking is a holistic approach to analysis that focuses on the way that a system's constituent parts interrelate and how systems work over time and within the context of larger systems.

In general, a framework is a real or conceptual structure intended to serve as a support or guide for the building of something that expands the structure into something useful.

A sniglet is a word that should be in the dictionary but isn't.

Teleoperation, also called telerobotics, is the technical term for the remote control of a robot.

Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.

Android OS is a Linux-based mobile operating system that primarily runs on smartphones and tablets.

A motor vehicle record (MVR) is the documentation of a person’s driving history. The information in an MVR includes personally identifiable information (PII) as well as information about the driver's traffic citations, vehicular crimes, accidents, driving under the influence (DUI) convictions and the number of points on the individual’s driver’s license.

United States Department of Energy (DOE) is a federal cabinet agency that is tasked with overseeing the energy economy, energy policies and energy security of the U.S. The agency creates policies for nuclear power, fossil fuel and alternative energy sources.

Quick Network Security & Hardware Refreshers School is out for college students across the US, but the learning never stops for IT professionals.

Deductive reasoning is a logical process in which a conclusion is based on the accordance of multiple premises that are generally assumed to be true.

A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole numbers that can be divided evenly into another number.

A unique identifier (UID) is a numeric or alphanumeric string that is associated with a single entity within a given system.

BIOS (basic input/output system) is the program a personal computer's microprocessor uses to get the computer system started after you turn it on. It also manages data flow between the computer's operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.

Cache memory, also called CPU memory, is high-speed static random access memory (SRAM) that a computer microprocessor can access more quickly than it can access regular random access memory (RAM).

A processor register is one of a small set of data holding places that are part of a processor, or CPU, in a computer.

A spray-on antenna is a conductive material that can be sprayed onto nearly any surface to create a thin, lightweight and flexible antenna.

Quantum theory is the theoretical basis of modern physics explaining the nature and behavior of matter and energy on the atomic and subatomic level, sometimes called quantum mechanics or quantum physics. This definition provides an introduction to quantum theory.

A quantum microphone is an extremely device that detects the smallest particles of sound, such as packets of vibrational energy called phonons.
