grade of service (GS)

The probability of a call being blocked by busy trunks, expressed as a decimal fraction, and usually meaning the busy-hour

probability.

host

On the Internet, a host, or host computer, can serve as both way station and entry point for network users. Hosts serve

information to remote users, for example using World Wide Web or Gopher. They also provide access to the Internet for local

users, capable of logging in through a particular account. A host is similar to node, except that “host” usually implies a

computer system, whereas “node” generally applies to any networked system, including access servers and routers. See node.

hypertext

The World Wide Web is built around this concept. Documents are formatted with special tools that permit authors to link

information to other documents of relevance elsewhere on the Internet. The Web is composed of “pages,” documents written

in hypertext, or HyperText Markup Language (HTML). Using this information, graphical browsers like Mosaic or Netscape

display images and text. By clicking on highlighted text, one can move to related information and images located anywhere

around the world, reading and accessing countless pages of online information in various media (audio, video, pictures, etc.).

A nongraphical browser called Lynx also enables access to Hypertext documents, with keystrokes instead of a mouse.

information service

The offering for generating, acquiring, storing, transforming, processing, retrieving, utilizing, making information available

using telecommunications. This service includes electronic publishing, but does not include management, control, or operation

of a telecommunications system or the management of a telecommunications service.

ingress interface

Interfaces used for inbound traffic flow.

interexchange carrier (IXC)

Telecommunications providers that provide service between local service areas.

Internet

An international network of computer networks with common protocol standards. World wide computer interconnection.

Provides any computer with the capability of linking to any and all other computers through mainframe computer links and

telephone connections.
