Term Definition
Samba(SMB) A client/server protocol that provides file and printer sharing between computers. In addition SMB can share serial ports and communications abstractions such as named pipes and mail slots. SMB is similar to remote procedure call (RPC) specialised for file system access. SMB was developed by Intel, Microsoft, and IBM in the early 1980s. It has also had input from Xerox and 3Com. It is the native method of file and print sharing for Microsoft operating systems; where it is called Microsoft Networking. Windows for Workgroups, Windows 95, and Windows NT all include SMB clients and servers. SMB is also used by OS/2, Lan Manager and Banyan Vines. There are SMB servers and clients for Unix, for example Samba and smbclient.
 
SamplingScanners. The process of converting analogue data into digital data by taking a series of samples or readings at equal time intervals.
 
Scalability/ ReliabiltyDisributed network support, 24 x 7 administration, replication and large repository support.
 
ScreenPrinters / Scanners. To break up continuous-tone copy into dots for reproduction as a halftone. Line screens are designated by the number of ruled lines they contain: from 50 lines per inch to 500 lines per inch. The greater the number of lines per inch, the sharper and fine the printed half-tone. The selection of the screen is dictated by the paper, press, the nature of the copy
 
Screen AnglesPrinters / Scanners. The angles used to offset the different films in process colour separations. Proper screen angles are critical to minimize moire' patterns
 
Screen RulingPrinters / Scanners. The number of lines per inch in the halftone screen. The lower the number, the larger and more widely spaced the dots. Higher screen rulings allow reproduction of fine detail.
 
SCSIGeneral computing. Small Computer Systems Interface A parallel interface allowing the pooling of up to 56 units (computer, printer, storage devices, etc.) on a single bus although in practice only 8 units are supported.
 
SDISelective Dissemination of Information, A system by which a user is supplied with information on subjects of his/her interest on an ongoing process
 
Search And RetrievalProvides for easy search of documents based on user and system defined keywords.
 
Security PolicyRules, which govern and identify the relationships between members and the objects of an information domain.
 
Security Servicesactivities that assist in, or provide for, the protection of information. Security services are provided by security mechanisms. Security mechanisms are diverse and include items such as guards, fences, cryptographic software, badges, or labels. The security services defined here are mutually supporting and often overlapping in the services provided. Although the definitions are provided in terms of people as individuals, they apply to groups, processes, and other agents or objects.
 
Seek TimeStorage products. The time required for moving the head from the current track to a specified track. The seek time does not include the average latency.
 
SeriesDocuments forming an entity within an archive or group e.g. minute books, out-going correspondence, clinical records.
 
SGMLThe Standardised General Mark-up Language, (ISO/IEC 8879:1986, now incorporating TC3) is a standard supporting the electronic processing, preservation and delivery of text-orientated information. SGML focuses on the description of the structure instead of the form, and is medium-independent. SGML is a superset of XML, and is used to define HTML.
 
Signature tabletAn input device to record an electronic version of a personal signature. The signature may be captured as a flat image, or further data may be recorded depending on the application.
 
SimplexScanners. Single sided
 
SkewStorage products. The actual or apparent local spacing (parallel to the reference edge) between two track elements of a row (DIN 66010), generally: shift, spacing.
 
SpecklingScanners. Isolated light pixels in predominantly dark image areas, sometimes caused by incorrect readings or noise in the scanning device.
 
SputteringStorage products. The application of a magnetic layer without a binder by means of ionic bombardment in a vacuum.
 
SSADMStructured Systems Analysis and Design Methodology.
 
St506/412 InterfaceComputer interfaces. This interface is an advancement of the floppy interface developed by Shugart. This standard interface for hard disks allows transfer rates of up to 5Mbits/second.
 
StandardA document defining the criteria to be used for a particular operation, e.g. coding.
 
Standard ProcedureA detailed written description of a specific task; it is mandatory that the procedures described are followed. Standard Procedures are equivalent to Standard Operating Procedures required by Good Laboratory Practice regulations.
 
Start/Stop Unit CommandStorage products. A SCSI device level 6 byte command for stopping or starting the platter spindle motor. Regardless of how any hardware settings have been configured the drive will respond to this command.
 
Stepper MotorStorage products. Type of drive for head movement with low-cost hard disk drives.
 
StorageThe function of storing records for future retrieval and use.
 
StructureThe structure of a document is understood to mean the logical structure of that document. In the XML format, this structure is described with a DTD or XML schema. Distinctive elements are, for example: address, subject, contents, signature.
 
Subtractive PrimariesPrinters / Scanners. The inks (cyan, magenta, and yellow) used in printing to create different colours. In contrast to additive primaries, these produce darker colours when combined. Another term for primary colourants.
 
SurrogateA copy of a record.
 
SVGScalable Vector Graphics is the description of an image as an application of the Extensible Markup Language (XML). Any program such as a Web browser that recognizes XML can display the image using the information provided in the SVG format.
 
SystemA group of interacting, interrelated, or interdependent elements forming a complex whole. A network of related computer software, hardware, and data transmission devices.
