TCP
(Transmission Control Protocol) is the transport protocol in TCP/IP that ensures
messages over the network are transmitted accurately and completely.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol) is the main Internet
communications protocol suite. TCP ensures that data is completely sent and
received at the other end. The IP component of TCP/IP provides data routability,
meaning that data packets contain the destination station and network addresses,
enabling TPC/IP messages to be sent to multiple networks within the LAN or in
the WAN.
UDP
(User Datagram Protocol) is a protocol within TCP/IP that is used to transport
information when accurate delivery isn’t necessary (for example, realtime video
and audio where packets can be dumped since there is no time for retransmitting
the data).
Virtual Servers
Virtual Servers allow Internet users access to services, such as Web or FTP,
running on your local network via the WAN IP address of the IP8100 series
telephone. This is also referred to as opening ports or port forwarding. The
Virtual Server forwards requests for the specified service to the specified IP
address on your LAN.
VoIP
VoIP (Voice Over Internet Protocol) is a method used to deliver voice information
over the Internet. VoIP services allow telephone calls using your PC or LAN.
WAN
WAN (Wide Area Network) is a communications network that covers a wide
geographic area such as a country (contrasted with a LAN, which covers a small
area such as a company building).
