Defragmentation is a process that reduces the amount of fragmentation. It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of contiguous regions (fragments). It also attempts to create larger regions of free space using compaction to impede the return of fragmentation. Some defragmentation utilities try to keep smaller files within a single directory together, as they are often accessed in sequence.

A network designed to operate effectively over extreme distances such as those encountered in space communications or on an interplanetary scale.

DELMIA V5 allows manufacturers to interact with factory processes early in the design stage and months before actual production commitment. Engineers, management, and stakeholders can have a 3D visualisation of the real world with the ability to evaluate “what-if scenarios,” make changes, optimise shop floor operations, and identify and eliminate costly errors and design mistakes. This allows any enterprise to facilitate higher quality and foster greater innovation.

Delphi is an integrated development environment (IDE) for console, desktop graphical, web, and mobile applications. It was originally developed by Borland as a rapid application development tool for Windows, and as the successor of Borland Pascal. Delphi and its C++ counterpart, C++Builder, shared many core components, notably the IDE and VCL, but remained separate until the release of RAD Studio 2007. RAD Studio is a shared host for Delphi, C++Builder, and others. Delphi's compilers use their own Object Pascal dialect of Pascal and generate native code for several platforms: 32- and 64-bit Windows, 32-bit Mac OS X, iOS and Android.

Descriptive analytics as the name implies they “Describe”, or summarize raw data and make it something that is interpretable by humans. They describe the past. The past refers to any point of time that an event has occurred, whether it is one minute ago, or one year ago. Descriptive analytics are useful because they allow us to learn from past behaviors, and understand how they might influence future outcomes.

A mathematical process that describes real-world events and the relationships between factors responsible for them. The process is used by consumer-driven organizations to help them target their marketing and advertising efforts.
