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.
