- sig file
A piece of text (e.g. contact details) which automatically appears at the end of an email. 
- signal
Electrical or electromagnetic energy transmitted from one point in a circuit to another along the channels connecting them. A signal can carry data which is either analogue or digital. - silicon chip
The popular name for an integrated circuit is a (silicon) chip; a solid state micro-circuit in which all the components (such as transistors and capacitors) are formed within a very thin slice of silicon. - simple object access protocol (SOAP)
A standard for exchanging XML-based messages over a network, and allows programs running in different operating systems to communicate. - simplex
Refers to the direction of data transmission. It may be in both directions at the same time, called duplex or full duplex; in only one direction at a time, called half duplex; or in one direction only, called simplex. - simulation
Simulation software uses a model that has been developed (e.g. a model of how a component works), to show the effect of different conditions. - single spacing
Lines which are single spaced do not have a blank line between each line of text. - single stepping
Step mode, or single stepping, is the execution of a program one statement at a time under user control. It allows the user to observe the effects of each statement after it has been executed. - single thread
One set of processing. This may be the traditional simple program (which is not designed to multi-thread) or one thread out of several being processed in a more complex system. - single-user licence
A single-user licence means software can only be used on one computer. - site licence
A site licence is where any number of computers may use the software at a single location. One payment is made to allow the multiple installation. - slide
In a presentation, a slide is a single frame which can include text, graphics and other content. - slide master
In a presentation package, this is a special slide which is the template for all the slides in the presentation, and contains all the styles and formatting. - slider bar
Where the display of an application is too big for the window, a slider bar is provided to move the displayed portion of the application vertically or horizontally. Also called 'scroll bar'. - slideshow presentation
A presentation is a series of slides, produced by multimedia presentation software. Presentations are usually displayed on a large monitor which the whole audience can see, or projected on to a large screen by a projector. - slot
A socket which is provided in a computer to allow additional components, e.g. additional disk drives and network interfaces, to be added to the computer later. These sockets are also called expansion slots. The more slots that are provided, the greater the number of extra components that can be added. - small computer systems interface (SCSI)
A small computer systems interface (SCSI) is designed to connect a wide range of devices to microcomputers at minimum cost, e.g. disk drives and scanners which need a high data transfer rate. It is widely used in general microcomputing. Each SCSI interface can connect up to seven peripheral devices. - small scale integration (SSI)
A type of integrated circuit with up to 20 logic gates on a chip; typically they are used for (hard) wired logic circuits. - smart card
A plastic credit card sized card that contains one or more semiconductor chips. - SMTP
Simple Mail Transfer Protocol. A TCP/IP protocol used in the transfer of email between computer systems. The user
