Short for color super-twist nematic, an LCD technology developed by Sharp Electronics Corporation. Unlike TFT, CSTN is based on a passive matrix, which is less expensive to produce. The original CSTN displays developed in the early 90’s suffered from slow response times and ghosting. Recent advances in the technology, however, have made CSTN a viable alternative to active-matrix displays. New CSTN displays offer 100ms response times, a 140 degree viewing angle, and high-quality color rivaling TFT displays – all at about half the cost.
A newer passive-matrix technology called High-Performance Addressing (HPA) offers even better response times and contrast than CSTN.
Short for Channel Service Unit/Data Service Unit. The CSU is a device that connects a terminal to a digital line. Typically, the two devices are packaged as a single unit. The dSU is a device that performs protective and diagnostic functions for a telecommunications line. You can think of it as a very high-powered and […]
Short for comma-separated values, another name for the comma-delimited format of data representation.
Short for computer-telephony-integration, which refers to systems that enable a computer to act as a call center, accepting incoming calls and routing them to the appropriate device or person. Today’s CTI systems are quite sophisticated and can handle all sorts of incoming and outgoing communications, including phone calls, faxes, and Internet messages.
CTIA – The Wireless Association is an international nonprofit organization that represents all sectors of wireless communications including cellular, personal communication services and enhanced specialized mobile radio. Founded in 1984 CTIA represent service providers, manufacturers, wireless data and internet companies, as well as other wireless contributors.
Short for control unit, it is a typical component of the CPU that implements the microprocessor instruction set. It extracts instructions from memory and decodes and executes them, and sends the necessary signals to the ALU to perform the operation needed. Control Units are either hardwired (instruction register is hardwired to rest of the microprocessor) […]
