`pants with a common interest in a particular subject.
`top-level domain n. In the domain-name system of
`Internet addresses or DNS hierarchy, any of the
`broadest category of names, under which all domain
`names fit. Top-level domains for sites in the United
`States include .com, .edu, .gov, .net, and .org. See
`also DNS (definition 1), major geographic domain.
`top-of-file n. 1. The beginning of a file. 2. A symbol
`used by a program to mark the beginning of a file(cid:173)
`the first character in the file or, in an indexed (or(cid:173)
`dered) database, the first indexed record. Acronym:
`TOF. See also beginning-of-file.
`topology n. The configuration or layout of a network
`formed by the connections between devices on a
`LAN (local area network) or between two or more
`LANs. See also bus network, LAN, ring network,
`star network, token ring network, tree network.
`total bypass n. A communications network that uses
`satellite transmission to bypass both local and long(cid:173)
`distance telephone links.
`total cost of ownership n. Specifically, the cost of
`owning, operating, and maintaining a single PC.
`More generally, the cost to businesses and organiza(cid:173)
`tions of setting up and maintaining complex and far(cid:173)
`reaching networked computer systems. Total cost of
`ownership includes the up-front costs of hardware
`and software added to later costs of installation, per(cid:173)
`sonnel training, technical support, upgrades, and re(cid:173)
`pairs. Industry initiatives designed to lower the total
`cost of ownership include centralized network man(cid:173)
`agement and administration, as well as hardware so(cid:173)
`lutions in the form of network-based computers with
`or without local storage and expansion capability.
`See also cost of ownership (CO).
`touch pad n. A variety of graphics tablet that uses
`pressure sensors, rather than the electromagnetics
`used in more expensive high-resolution tablets, to
`track the position of a device on its surface. See also
`absolute pointing device, graphics tablet.
`touch screen n. A computer screen designed or modi(cid:173)
`fied to recognize the location of a touch on its sur(cid:173)
`face. By touching the screen, the user can make a
`selection or move a cursor. The simplest type of
`touch screen is made up of a grid of sensing lines,
`which determine the location of a touch by matching
`
`Toolbar.
`
`toolbox n. A set of predefined (and usually precom(cid:173)
`piled) routines a programmer can use in writing a
`program for a particular machine, environment, or
`application. Also called toolkit. See also library
`(definition 1).
`Toolbox n. A set of routines stored mostly in the read(cid:173)
`only memory of a Macintosh that provides applica(cid:173)
`tion programmers with the tools needed to support
`the graphical interface characteristic of the computer.
`Also called User Interface Toolbox.
`Tool Command Languageffool Kit n. See Tclffk.
`toolkit n. See toolbox.
`top-down design n. A program design methodology
`that starts with defining program functionality at the
`highest level (a series of tasks) and then breaks down
`each task into lower-level tasks, and so on. See also
`bottom-up programming, top-down programming.
`Compare bottom-up design.
`top-down programming n. An approach to program(cid:173)
`ming that implements a program in top-down fash(cid:173)
`ion. Typically, this is done by writing a main body
`with calls to several major routines (implemented as
`stubs). Each routine is then coded, calling other,
`lower-level, routines (also done initially as stubs).
`See also bottom-up design, stub, top-down design.
`Compare bottom-up programming.
`topic drift n. The tendency of an online discussion to
`move from its original subject to other related or un(cid:173)
`related subjects. For example, someone in a confer(cid:173)
`ence devoted to television may ask about a news
`program; then somebody else may say something
`about a story on that program about food poisoning,
`which leads somebody else to start a general discus-

`vertical and horizontal contacts. Another, more accu(cid:173)
`rate type uses an electrically charged surface and
`sensors around the outer edges of the screen to detect
`the amount of electrical disruption and pinpoint ex(cid:173)
`actly where contact has been made. A third type has
`infrared light-emitting diodes (LEDs) and sensors
`around the outer edges of the screen. These LEDs
`and sensors create an invisible infrared grid, which
`the user's finger interrupts, in front of the screen.
`Compare light pen.
`touch-sensitive display n. See touch screen.
`touch-sensitive tablet n. See touch pad.
`touch tone dialing n. The signaling system used in
`telephones with touch-tone keypads, in which each
`digit is associated with two specific frequencies.
`During dialing, these frequencies-for example,
`1336 Hz and 697 Hz for the number 2-are transmit(cid:173)
`ted to the telephone company. Also called DTMF,
`Dual Tone Multiple Frequency.
`tower n. A microcomputer system in which the cabi(cid:173)
`net for the central processing unit (CPU) is tall, nar(cid:173)
`row, and deep rather than short, wide, and deep. The
`motherboard is usually vertical, and the disk drives
`are often perpendicular to the motherboard. A tower
`cabinet is at least 24 inches tall. See the illustration.

`Transaction Processing Council.
`TP monitor n. Short for teleprocessing monitor or
`transaction processing monitor. A program that con(cid:173)
`trols the transfer of data between terminals (or cli(cid:173)
`ents) and a mainframe (or one or more servers) so as
`to provide a consistent environment for one or more
`online transaction processing (OLTP) applications. A
`TP monitor may also control the appearance of the
`screen displays and check input data for proper for(cid:173)
`mat. See also client (definition 3), mainframe com(cid:173)
`puter, OLTP, server (definition I).
`trace vb. To execute a program in such a way that the
`sequence of statements being executed can be ob(cid:173)
`served. See also debugger, single step.
`track' n. One of numerous circular data storage areas
`on a floppy disk or a hard disk, comparable to a
`groove on a record but not spiral. Tracks, composed
`of sectors, are recorded on a disk by an operating
`system during a disk format operation. On other stor(cid:173)
`age media, such as tape, a track runs parallel to the
`edge of the medium. See the illustration.

`on a disk or a magnetic tape. 4. In computer graph(cid:173)

`another pointing device.
`trackball n. A pointing device that consists of a ball
`resting on two rollers at right angles to each other,
`which translate the ball's motion into vertical and
`horizontal movement on the screen. A trackball also
