Networking Terms
Full-Duplex
Independent, simultaneous two-way transmission in both directions, as opposed to half-duplex
transmission
Gateway
A device for interconnecting two or more dissimilar networks. It can translate all protocol levels
from the Physical layer up through the Applications layer of the OSI model, and can therefore
interconnect entities that differ in all details.
Hardware Address
See Network Address.
Host
Generally a node on a network that can be used interactively, i.e., logged into, like a computer.
Host Table
A list of TCP/IP hosts on the network along with their IP addresses.
IEEE 802.3
The IEEE (Institute of Electrical and Electronic Engineers) standard that defines the CSMA/CD
media-access method and the physical and data-link layer specifications of a local area network.
Among others, it includes 10BASE2, 10BASE5, 10BASE-FL, and 10BASE-T Ethernet
implementations.
Internet
A series of interconnected local, regional, national and international networks, linked using
TCP/IP. Internet links many government, university, and research sites. It provides E-mail, remote
login and file transfer services.
Internetworking
General term used to describe the industry composed of products and technologies used to link
networks together.
IP Address
See Network Address.
ISO Layered Model
The International Standards Organization (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.
KB

Kbps
