  • TCP/IP

Transmission Control Protocol/Internet Protocol
TCP/IP is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is provided with a TCP/IP driver just as every other computer that you may send messages to or get information from also has a TCP/IP driver.

  • TDM

Time Division Multiplexer
A device which divides the time available on its composite link among its channels, usually interleaving bits (Bit TDM) or characters (Character TDM) of data from each terminal.

  • Telnet

The virtual terminal protocol in the Internet suite of protocols. It lets users on one host access another host and work as terminal users of that remote host. Instead of dialing into the computer, the user connects to it over the Internet using Telnet. When issuing a Telnet session, it connects to the Telnet host and logs in. The connection enables the user to work with the remote machine as though it were a terminal connected to it.

  • TFTP

Trivial File Transfer Protocol
A simplified version of the File Transfer Protocol that transfers files but does not provide password protection or user directory capability.

  • Throughput

The amount of information transferred through the network between two users in a given period, usually measured in the number of packets per second (pps).

  • ToS

Type oService Field
In a QoS scheme, an eight-bit field that lets values from 0 to 15 be assigned to request special handling of traffic (for example, minimize delay, maximize throughput). The ToS field is being phased out in favor of DSCP.
