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.
