Ethernet works by simply checking the wire before sending data. Sometimes two
stations send at precisely the same time in which case a collision is detected and
retransmission is attempted. Ethernet is a widely-implemented standard for
LAN’s. See also 10Base-T or 100Base-T.
Ethernet Hub - A networking device that allows many hosts to be connected
together in a star configuration. Multiple hubs may be daisy-chained together
increasing capacity and extending the range.
Firewall - A security device (hardware or software) that controls access from the
Internet to a local network by using identification information associated with
TCP/IP packets to make a decision about whether to allow or deny access. This
decision is based on a set of defined rules that describe which packets or sessions
are allowed.
Frame Relay - A high-speed connection-oriented packet switching WAN proto-
col using variable-length frames.
FTP (File Transfer Protocol) - The protocol used on the Internet for transferring
files to and from remote computer systems.
Gateway - In networking, a combination of hardware and software that links two
different types of networks. Gateways between e-mail systems, for example,
allow users on different e-mail systems to exchange messages.
GUI (Graphical User Interface) - A program interface that takes advantage of the
computer’s graphics capabilities to make the program easier to use.
Host - A computer or any device connected to a TCP/IP network.
IEEE 803.2 - The protocol that defines an Ethernet network at the physical layer
of network signaling and cabling.
Interface - In the context of the User’s Guide, refers to the interface between the
X320R and any network. For example, the
L0
interface refers to the interface
between the X320R and the LAN.
Interoperability - The ability of equipment from multiple vendors to communi-
cate using standardized protocols.
IP (Internet Protocol) - A Layer 3 networking protocol used for Internet packet
delivery. Keeps track of the Internet addresses for different nodes, routes outgo-
ing messages, and recognizes incoming messages.
