TCP
Transmission Control Protocol - The major transport protocol in the Internet suite of
protocols provides reliable, connection-oriented full-duplex streams.

TFTP
Trivial File Transfer Protocol. A simple file transfer protocol (a simplified version of FTP)
that is often boot diskless workstations and other network devices such as routers over a
network (typically a LAN).
Telnet
The virtual terminal protocol in the Internet suite of protocols - Allows users of one host to
log into a remote host and act as normal terminal users of that host.

Transparent bridging
The intelligence necessary to make relaying decisions exists in the bridge itself and is thus
transparent to the communicating workstations. It involves frame forwarding, learning
workstation addresses, and ensuring no topology loops exist (in conjunction with the
Spanning-Tree algorithm).

UDP
User Datagram Protocol - A connectionless transport protocol that runs on top of TCP/IP's
IP. UDP, like TCP, uses IP for delivery; however, unlike TCP, UDP provides for exchange
of datagram without acknowledgments or guaranteed delivery. Best suited for small,
independent requests, such as requesting a MIB value from an SNMP agent, in which first

Static IP Address
A static IP address is an IP address permanently assigned to computer in a TCP/IP network.
Static IP addresses are usually assigned to networked devices that are consistently
accessed by multiple users, such as Server PCs, or printers. If you are using your Rout
share your cable or DSL Internet connection, contact your ISP to see if they have ass
your home a static IP address. You will need that address during your Router's
configuration.

Subne
For routing purposes, IP networks can be divided into logical subnets by using a subnet
mask. Values below those of the mask are valid addresses on the subnet.
