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.
