`scripting language
`
`The instructions usually use the rules and syntax
`of the application or utility. See also macro.
`n. A
`scripting language \skrip’téng lang‘w9j\
`simple programming language designed to per—
`form special or limited tasks, sometimes associated
`with a particular application or function. An exam-
`ple of a scripting language is Perl. See also Perl,
`script.
`scroll \skr61\ vb. To move a document or other
`
`data in a window in order to View a particular por—
`tion of the document. Scrolling may be controlled
`by the mouse, arrow keys, or other keys on the
`keyboard. See also scroll bar.
`scroll arrow \skrél’ ar‘6\ n. See scroll bar.
`
`scroll bar \skrél’ bar\ n. In some graphical user
`interfaces, a vertical or horizontal bar at the side or
`bottom of a display area that can be used with a
`mouse for moving around in that area. Scroll bars
`often have four active areas: two scroll arrows for
`
`moving line by line, a sliding scroll box for moving
`to an arbitrary location in the display area, and
`gray areas for moving in increments of one Win—
`dow at a time. See the illustration.
`‘
`scroll box \skrol’ boks\ n. See elevator.
`Scroll Lock key \skrol’ lok ké‘\
`71. On the IBM
`PC/XT and AT and compatible keyboards, a key on
`the top row of the numeric keypad that controls
`the effect of the cursor control keys and sometimes
`prevents
`the screen from scrolling. On the
`enhanced and Macintosh keyboards, this key is to
`the right of the function keys on the top row. Many
`modern applications ignore the Scroll Lock setting.
`SCSI \skuz’é, S‘C-S—I’\ n. Acronym for Small Com-
`puter System Interface, a standard high—speed par—
`allel interface defined by the X3T9.2 committee of
`the American National Standards Institute (ANSI).
`
`A SCSI interface is used to connect microcomput—
`ers to SCSI peripheral devices, such as many hard
`disks and printers, and to other computers and
`local area networks. Compare ESDI, IDE.
`SCSI-1 \skuz‘é—wan’, S—C-S-I‘wan’\ 72. See SCSI.
`SCSI-2 \skuz‘é-toT)’,
`S-C—S—I‘—t6‘o’\
`n. An
`en-
`hanced ANSI standard for SCSI (Small Computer
`System Interface) buses. Compared with the origi—
`nal SCSI standard (now called SCSI-1), which can
`transfer data 8 hits at a time at up to 5 MB per sec-
`ond, SCSI-2 offers increased data width, increased
`speed, or both. A SCSI—2 disk drive or host
`adapter can work with SCSI—1 equipment at the
`older equipment’s maximum speed. See also Fast
`SCSI, Fast/Wide SCSI, SCSI, Wide SCSI. Compare
`UltraSCSI.
`
`SCSI bus \skuz’é bus, S‘C-S—I’\ n. A parallel bus
`that carries data and control signals from SCSI
`devices to a SCSI controller. See also bus, control—
`ler, SCSI device.
`SCSI chain \skuz’e chan‘, S‘C—S—I’\ n. A set of
`devices on a SCSI bus. Each device (except the
`host adapter and the last device) is connected to
`two other devices by two cables, forming a daisy
`chain. See also daisy chain, SCSI.
`.
`SCSI connector \skuz’e ka—nekkar, S‘C—S—I’\ n. A
`cable connector used to connect a SCSI device to
`
`a SCSI bus. See the illustration on the next page.
`See also bus, connector (definition 1), SCSI device.
`SCSI device \skuz’é da—vis‘, S‘C—S-I’\ n. A periph—
`eral device that uses
`the SCSI
`standard to
`exchange data and control signals with a com-
`puter’s CPU. See also peripheral, SCSI.
`SCSI 11) \skuz’é I-D’ S—C-S—I’\ n. The unique iden—
`tity of a SCSI device. Each device connected to a
`SCSI bus must have a different SCSI ID. A maxi—

`
`screen pitch \skrén’ pich\ n. A measurement of a
`computer monitor’s screen density, representing
`the distance between phosphors on the display.
`The lower the number, the more detail can be dis-
`played clearly. For example, a .28-dot-pitch screen
`has better resolution than one with .32. See the
`illustration. See also phosphor.
`n. A utility that
`screen saver \skrén’ sa‘v9r\

`image after a specified amount of time passes .
`without the keyboard being touched or the mouse

`tible to this problem, screen savers remain popular
`for their decorative and entertainment value. See
