Short for GNU Privacy Guard and also abbreviated as GnuPG, GPG is the GNU project’s free software implementation of the OpenPGP standard as defined by RFC4880. GPG is specifically a command line tool that enables you to encrypt and sign your data and communication and includes a key management system as well as access modules for all kind of public key directories.
Short for General Public License, the license that accompanies some open source software that details how the software and its accompany source code can be freely copied, distributed and modified. The most widespread use of GPL is in reference to the GNU GPL, which is commonly abbreviated simply as GPLwhen it is understood that the […]
Short for ground penetrating radar, a UWB imaging technology used for subsurface earth exploration. GPR uses electromagnetic wave propagation and scattering to image and identify changes in electrical and magnetic properties in the ground. GPR systems have wide applications, such as locating underground utility lines, monitoring airplane runways for structural integrity, detecting unexploded land mines, […]
- General Packet Radio Service (GPRS)
Short for General Packet Radio Service, a standard for wireless communications which runs at speeds up to 115 kilobitsper second, compared with current GSM (Global System for Mobile Communications) systems’ 9.6 kilobits. GPRS, which supports a wide range of bandwidths, is an efficient use of limited bandwidth and is particularly suited for sending and receiving […]
Acronym for GUID partition table Computers with an Intel Itanium processor use the Extensible Firmware Interface (EFI) between firmware, hardware, and OS. EFI has a new type of disk partitioning system, called the GUID (globally unique identifier) partition table (GPT). Unlike Master Boot Record (MBR) partitioned disks, data critical to platform operation is located in […]
- Graphics Processing Unit (GPU)
A GPU, or graphics processing unit, is used primarily for 3-D applications. It is a single-chip processor that creates lighting effects and transforms objects every time a 3D scene is redrawn. These are mathematically-intensive tasks, which otherwise, would put quite a strain on the CPU. Lifting this burden from the CPU frees up cycles that […]
