Gigabit Ethernet is a speed definition for the Ethernet protocol which can provide 1-gigabit data transmission per second. 1 Gigabit is equal to the 1,000Mbps speed. Gigabit Ethernet also refers to an ethernet port which can provide 1-gigabit speed. Gigabit Ethernet is an established standard which is mainly described IEEE 1000Base-T (802.3ab) and later TIA 1000Base-TX is created which requires CAT6 cable to work in a reliable fashion.

A glitch, in computing, refers to a small and fleeting error in a system that occurs due to unknown causes. While the actual cause of a glitch is unknown, it can potentially cause serious harm to the system, including power failure, temporary loss of service or data loss. There's a glitch in the etymology of glitch - the origins of the word are not known for sure, though it may derive from the Yiddish glitsh, meaning "slippery place."

Graphical User Interface, a system that simplifies selecting computer commands by enabling the user to point to symbols or illustrations (called icons) on the computer screen with a mouse. It is a visual representation of several textual actions presented to the user for easy interaction with the system. The communication is achieved, between user and machine, by interacting with "icons", "interactive text menus" and virtual bidimensional or tridimensional spaces rather than the usual text-based or command-based communication (GUI differs from CLI). While mouse and keyboard are sufficient for desktop computers, they do not work as well for mobile devices, such as smartphones and tablets. Therefore, mobile operating systems are designed to use a touchscreen interface. Many mobile devices can now be controlled by spoken commands as well.
