T
- TCP
- The Transmission Control Protocol that operates at Layer 4 of the OSI reference model and enables guaranteed or reliable delivery of IP packets.
- TFTP
- The Trivial File Transfer Protocol (TFTP) is one of the many utilities built into the TCP/IP family of protocols. This mechanism enables you to transfer files between hosts with a minimum of complexity.
- three-way handshake
- Each and every communications session using TCP begins with a three-way handshake between the source and destination machines. This handshake enables the two machines to coordinate their activities and ensure reliable delivery of future packet transmissions.
- TIA
- The Telecommunications Industry Association sets open technical standards for the telecommunications industry. One of its more significant contributions to data networking was its collaboration with the EIA to produce performance-based categories of standards for network wire.
- Time-To-Live
- The Time-To-Live (TTL) field tracks the number of network devices that the IP packet passes through. When a certain threshold is reached, the packet is discarded.
- tracert
- A tool that uses ICMP to help you map out the actual path that your IP packets take when sent through a TCP/IP network.
- See also [traceroute]
- traceroute
- Some operating systems name the ICMP trace utility traceroute. Traceroute is the same as tracert.
- transmission medium
- The transmission facility that connects your computer's network interface card to the network.
- trunk line
- A high-capacity telecommunications line that can carry multiple dial-up sessions simultaneously.
