`Interpretation of the printing code: the rightmost double—digit number is
`the year of the book’s printing; the rightmost single—digit number, the
`number of the book’s printing. For example, a printing code of 94-1

`
`time division multiplexing In local area networks, a tech-
`nique for transmitting two or more signals over the same cable by
`alternating them, one after the other. Time division multiplexing
`is used in baseband (digital) networks. See nmmd, frequency
`ollviiion multiplexing, local arm network (L/UV), and multiplexing.
`
`time out An interruption, resulting in a frozen keyboard, while
`the computer tries to access a device (or a remote computer) that
`isn’t responding as it should. The computer keeps trying for a
`predetermined time and then gives up, returning control to you,
`
`time-sharing A technique for sharing a multiuser computer’s
`resources in which each user has the illusion that he or she is die only
`person using the system. In die largest mainframe systems, hundreds
`or even thousands of people can use the system simultaneously with»
`out realizing that others are doing so. At times of peak usage, howv
`ever, system response time tends to decline noticeably.
`
`In graphical user interfaces such as Microsoft \Win—
`title bar
`dows, a bar that stretches across the top of a window, indicating
`the name of the document displayed in that window. The color of
`the title bar indicates whether the window is active. See graphical
`user inteiflzco (GU1}.
`
`toggle To switch back and forth between two modes or states.
`On the IBM l’C—compatible keyboard, for example, the Caps Lock
`key is a toggle key. Wheir you press the key the first time, you switch
`the keyboard into a caps—entry mode. When you press the key the
`second time, you switch the keyboard back to the normal mode, in
`which you must press the Shift key to type capital letters.

`
`token passing In local area networks, a network protocol
`in which a special bit configuration, called a token, is circulated
`among the vvorkstations. A node gains access to the network only
`if the node can obtain a free token. The node converts the token
`into a drztazfi'zzmo containing a network message.
`
`Every workstation constantly monitors the network to catch a
`token addressed to that workstation. \X/hen a workstation receives
`a token, it attaches an acknowledgment message to the data frame.
`\‘/<71-ten the data frame with an acknowledgment comes back to the
`source node, the node puts a token into circulation.
`
`Because token passing rules out the data collisions that occur when
`two devices begin transmitting at the same time, this channel
`access method is preferred for large. high-volume networks. See
`carrier sense multiple access with collision olozvciion (CSIMA/CD),
`contention, loml arm network (LAJV), and polling.
`
`token-ring network In local area networks, a network architec-
`ture that combines token passing with a hybrid star/ring topology.
`
`Developed by IBM and announced in 1986, the IBM ’l'oken—Ring
`Network uses a Multistation Access Unit at its hub. This unit is
`wired with twisted—pair cable in a star configuration with up to
`255 workstations, but the resulting network is actually a deccntral»
`ized ring network. See local area networ/e (LAIV) and to/zen porting.
`
`toner The electrically charged ink used in laser printers and
`photocopying machines. To form the image, toner is applied to an
`electrostatically charged drum and fused to the paper by a heating
`element. See laser printer and toner cartridge.
