scroll
the systematic movement of text or images, either up and down, or from side to side on a computer display screen with the use of the keyboard arrow keys, or a mouse. In scrolling down, a new line of text appears at the bottom of the screen as the line at the top disappears. To scroll up and down using a mouse, the user would place the mouse cursor on the scroll bar (a sliding rectangular button located on the right of the display), or on a stationary arrow button at either the top or bottom of the frame. In using the arrow button, the user would position the cursor on the button, left click, and hold the mouse button down. The contents of the screen will move up or down accordingly. To scroll using the sliding button, the user would place the mouse cursor on the button, left click the mouse, and leave the button pressed while moving the mouse either up or down. This causes the screen contents to move at the same speed as the mouse. To scroll using the arrow keys, a user simply presses the key that corresponds to the desired direction of the screen contents.


scroll bar
a rectangular sliding button located either on the right side and/or the bottom of a computer display screen used to move the screen’s contents accordingly. see scroll.


Scroll Lock key
a special key on PC and Macintosh keyboards whose function varies depending on the program running.


SCSI
(Small Computer Systems Interface) pronounced scuzzy, a parallel interface which is the leading standard for connecting high-performance peripherals to PCs and Macintosh computers. SCSI interfaces can accommodate a combination of up to seven peripherals, such as scanners, hard disks, tape backup devices and more. While SCSI is the exclusive peripheral interface for the Macintosh, PCs support several interfaces in addition to the SCSI.

SD Memory Card
(Secure Digital Memory Card) a flash memory card that provides storage for digital cameras, cellphones and PDAs. SD Memory Cards use the same 32x24mm form factor as the MultiMediaCard (MMC), but are slightly thicker (2.1mm vs. 1.4mm), and SD Card readers accept both formats. Introduced in 1999 by Panasonic, Toshiba and SanDisk, cards up to 4GB are available.


SDK
(Software Development Kit) programming tools that allow a programmer to create applications that will enhance the operation of other software.


SDRAM
(Synchronous Dynamic Random-Access Memory) an extremely fast type of DRAM running up to three times faster than conventional memory. SDRAM achieves this by synchronizing itself with the processor.


SDSL
(Symmetric Digital Subscriber Line) new technology requiring a special modem that allows for the sending of data over copper telephone lines at high speeds. Data can be transferred at rates of up to 3 Mbps because SDSL transmits on frequencies not used for regular voice transmission.


search and replace
the ability for a word processing application to find a specific word or phrase and replace it with another. Most programs will either automatically replace every chosen character string, or give the user the option of approving each of the changes. In Macintosh compatible software this feature is called find and replace.
