The resistance and reactance a wire offers to a change
in current as the current runs down the length of the
wire, measured in ohms.
Integrated IS-IS Routing protocol based on the OSI routing protocol IS-IS, but
with support for IP or other networks. Integrated IS-IS implementations send
only one set of routing updates and are more efficient than two separate implementations. |
| Internet |
|
The
world's largest internetwork, comprising large backbone
nets (MILNET< NSFNET, and CREN, for example) and
an array of regional and local campus networks worldwide.
It uses the Internet protocol suite. Access to the
Internet requires IP connectivity, or the ability to
Telnet to - or "pint" - other systems. |

that functions as a single network. Sometimes called
an internet, which is not synonymous
with the Internet. |

International Standards Organization. The ISO sets
standards for computers and communications. Its Open
Systems Interconnection (OSI) reference model specifies
how dissimilar computing devices such as Network Interface
Cards (NICs), bridges and routers exchange data over
a network. The model consists of seven layers. From
lowest to highest, they are: Physical, Data Link, Network,
Transport, Session, Presentation, and Application.
Each layer performs services for the layer above it. |
