TCP/ IP- (Transmission Control Protocol/Internet Protocol) A communications protocol developed under contract from the U.S. Department of Defense to inter-network dissimilar systems. Invented by Vinton Cerf and Bob Kahn, this de facto UNIX standard is the protocol of the Internet and has become the global standard for communications. TCP provides transport functions, which ensures that the total amount of bytes sent is received correctly at the other end. UDP, which is part of the TCP/IP suite, is an alternate transport that does not guarantee delivery. It is widely used for real time voice and video transmissions where erroneous packets are not retransmitted. TCP/IP is a routable protocol, and the IP part of TCP/IP provides this capability. In a routable protocol, all messages contain not only the address of the destination station, but the address of a destination network. This allows TCP/IP messages to be sent to multiple networks (subnets) within an organization or around the world, hence its use in the worldwide Internet. For more information go to our home page.

Tel Net- Tel Net is a terminal emulation protocol commonly used on the Internet and TCP/IP-based networks. It allows a user at a terminal or computer to log onto a remote device and run a program. Telnet was originally developed for ARPAnet and is an inherent part of the TCP/IP communications protocol. Although most computers on the Internet that allow Telnet access require users to have an established account and password, there are some that allow the public to run programs such as search utilities.

Temperature- Measure of hotness expressed in terms of any of several arbitrary scales, such as Fahrenheit, Celsius, or Kelvin. Heat flows from a hotter body to a colder one and continues to do so until both are at the same temperature. Temperature is a measure of the average energy of the molecules of a body, whereas heat is a measure of the total amount of thermal energy in a body. For more information on devices that measure temperature go to our home page.

Terminal Server- A computer or controller used to connect multiple terminals to a network or host computer. For more information go to our home page.

Thresholds- A threshold is a point at which a signal (voltage, current, etc.) is perceived as valid. For more information go to http://www.uptimedevices.com. For additional information go to our FAQ Manual.

Trap- To test for a particular condition in a running program; for example, to "trap an interrupt" means to wait for a particular interrupt to occur and then execute a corresponding routine. An error trap tests for an error condition and provides a recovery routine. A debugging trap waits for the execution of a particular instruction in order to stop the program and analyze the status of the system at that moment. For more information go to our home page. For additional information on how to setup the traps for your devices please go to our online FAQ Manual.

True RMS-  (Root Mean Square) A more accurate method used to measure electrical output in volts and watts. For more information go to our home page.
