Glossary of Terms

Glossary is usually defined as an alphabetical list of technical terms in some specialized field of knowledge. This knowledge base glossary provides a collection of knowledge base documents that define many technical terms. These terms are arranged alphabetically, but you can quickly jump to a specific term by selecting its first letter from the index of the knowledge base glossary below.

ONT
The Optical Network Terminal (ONT) is a small network interface device that Nex-Tech has installed on the outside wall of your location. There is a power cable that goes to the inside of your home to a Battery Back-Up Unit that is plugged into a standard AC outlet. You will first want to make sure that this power cable is plugged in and getting power. The Batter Back-up Unit will supply power to the ONT if the power has gone out or if the unit has become unplugged.
OS
An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function.
