transmitting information over Ethernet between different
manufacturers.
Protocol: A protocol is a set of rules for interaction agreed upon
between multiple parties so that when they interface with each
other based on such a protocol, the interpretation of their behavior
is well defined and can be made objectively, without confusion or
misunderstanding.
Router: A router is an intelligent network device that forwards
packets between different networks based on network layer
address information such as IP addresses.
Subnet Mask: A subnet mask, which may be a part of the TCP/IP
information provided by your ISP, is a set of four numbers (e.g.
255.255.255.0) configured like an IP address. It is used to create IP
address numbers used only within a particular network (as opposed
to valid IP address numbers recognized by the Internet, which must
be assigned by InterNIC).
TCP/IP, UDP: Transmission Control Protocol/Internet Protocol
(TCP/IP) and Unreliable Datagram Protocol (UDP). TCP/IP is the
standard protocol for data transmission over the Internet. Both TCP
and UDP are transport layer protocol. TCP performs proper error
detection and error recovery, and thus is reliable. UDP on the other
hand is not reliable. They both run on top of the IP (Internet
Protocol), a network layer protocol.
WAN: Wide Area Network. A network that connects computers
located in geographically separate areas (e.g. different buildings,
cities, countries). The Internet is a wide area network.
Web-based management Graphical User Interface (GUI): Many
devices support a graphical user interface that is based on the web
browser. This means the user can use the familiar Netscape or
Microsoft Internet Explorer to Control/configure or monitor the
device being managed.
