T TAPI - telephony application programming interface - Enables Windows programs to operate with a wide variety of telephony devices, including voice, data, fax, and video. text editor - A program used to create and edit files that contain only text; for example, Windows Notepad uses a text editor. Text editors do not usually provide word wrap or formatting functionality (the option to underline, change fonts, and so on). TPM - trusted platform module - A hardware-based security feature that when combined with security software enhances network and computer security by enabling features such as file and e-mail protection. travel module - A plastic device designed to fit inside the module bay of a portable computer to reduce the weight of the computer.

UPS - uninterruptible power supply - A backup power source used when the electrical power fails or drops to an unacceptable voltage level. A UPS keeps a computer running for a limited amount of time when there is no electrical power. UPS systems typically provide surge suppression and may also provide voltage regulation. Small UPS systems provide battery power for a few minutes to enable you to shut down your computer. USB - universal serial bus - A hardware interface for a low-speed device such as a USB-compatible keyboard, mouse, joystick, scanner, set of speakers, printer, broadband devices (DSL and cable modems), imaging devices, or storage devices. Devices are plugged directly in to a 4-pin socket on your computer or in to a multi-port hub that plugs in to your computer. USB devices can be connected and disconnected while the computer is turned on, and they can also be daisy-chained together. UTP - unshielded twisted pair - Describes a type of cable used in most telephone networks and some computer networks. Pairs of unshielded wires are twisted to protect against electromagnetic interference, rather than relying on a metal sheath around each pair of wires to protect against interference. UXGA - ultra extended graphics array - A video standard for video cards and controllers that supports resolutions up to 1600 x 1200. Glossary 209
