Static IP - If your Service Provider has assigned a fixed IP address; enter the
assigned IP address, subnet mask and the gateway address provided by your
service provider.
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 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.
TCP/IP - Transmission Control Protocol/Internet Protocol. This is the standard
protocol for data transmission over the Internet.
TCP - Transmission Control Protocol - TCP and UDP (User Datagram Protocol)
are the two transport protocols in TCP/IP. TCP ensures that a message is sent
accurately and in its entirety. However, for real-time voice and video, there is
really no time or reason to correct errors, and UDP is used instead.
UDP - User Datagram Protocol - A protocol within the TCP/IP protocol suite that
is used in place of TCP when a reliable delivery is not required. For example,
UDP is used for real-time audio and video traffic where lost packets are simply
ignored, because there is no time to retransmit. If UDP is used and a reliable
delivery is required, packet sequence checking and error notification must be
written into the applications.
UPnP - Universal Plug and Play is a protocol that allows for the automatic
discovery and control of networked devices and services.
