TDMA
Short for Time Division Multiple Access, a technology for delivering digital wireless service using time-division multiplexing (TDM). TDMA works by dividing a radio frequency into time slots and then allocating slots to multiple calls. In this way, a single frequency can support multiple, simultaneous data channels. TDMA is used by the GSM digital cellular system.

Time Domain Reflectometry is used to pinpoint flaws and problems in underground and aerial wire, cabling, and fiber optics. Time Domain Reflectometers send a signal down the conductor and measure the time it takes for the signal — or part of the signal — to return. The signal’s reflection begins at the flaw point. Once […]

- TCP-Friendly Rate Control
TCP-Friendly Rate Control (TFRC) is a congestion control mechanism designed for unicast flows operating in an Internet environment and competing with TCP traffic. It is designed for applications that use a fixed packet size, and vary their sending rate in packets per second in response to congestion. TFRC is a receiver-based mechanism, with the calculation […]
- Thin Film Transistor (TFT)
Short for thin film transistor, a type of LCD flat-panel display screen, in which each pixel is controlled by from one to four transistors. The TFT technology provides the best resolution of all the flat-panel techniques, but it is also the most expensive. TFT screens are sometimes called active-matrix LCDs.
- TFTP
Abbreviation of Trivial File Transfer Protocol, a simple form of the File Transfer Protocol (FTP). TFTP uses the User Datagram Protocol (UDP)and provides no security features. It is often used by servers to bootdiskless workstations, X-terminals, and routers.
