Safe Mode   Dico Tools
A cut-down version of Windows which you can launch instead of the full version for troubleshooting purposes.

SATA   Dico Tools
(Serial Advanced Technology Attachment) The latest high speed standard for connecting hard disks to your computer, replacing EIDE on most new computers.

Save   Dico Tools
Copy whatever you are working on from memory, which is lost when you switch off the computer, to permanent storage, usually the hard disk. It is a good idea to save frequently when you are working on something important, in case there is a sudden power cut or you make some awful mistake that trashes your document.

Scanner   Dico Tools
A device which makes high-resolution copies of printed images and text to use on a computer.

Screensaver   Dico Tools
A program that blanks the computer screen or displays images if you don't do anything for a few minutes, in Windows for example. Early screens could have images literally burned permanently onto the tube if left displaying the same thing all day. Much less of a problem with modern screens, and these days screensavers are mostly used for security (with a password to return to normal mode), or just for fun.

Scroll   Dico Tools
To scroll something is to move it up or down the screen, so you can see what is above or below the current position, for example at a website. A scroll-bar is a bar on the right-hand side (usually) of a window which allows you to move the text etc up and down the screen with a mouse. If the window is too wide to fit the screen there will be a scroll-bar at the bottom, so you can scroll the text left and right too.

SCSI   Dico Tools
(Small Computer Systems Interface; pr. "scuzzy") A fast system for controlling hard disks, tape drives, and various other add-ons. Sometimes used for a PC's main hard disk, but more often the main hard disk is controlled by an EIDE controller built into the motherboard. A SCSI controller would usually be installed as an expansion board. SCSI is a bit faster than EIDE, but more expensive.

Search Engine   Dico Tools

SoundBlaster   Dico Tools
The best known type of Soundcard, made by Creative Labs. Most modern soundcards are described as "SoundBlaster compatible" (or S/B compatible), meaning that they understand the same commands as the popular SoundBlaster range, and should therefore work with almost all programs.

Soundcard   Dico Tools
An expansion card which enables the PC to make sounds more sophisticated than a simple "beep!". Almost all modern PCs are fitted with soundcards; nowadays they are often built into the motherboard instead of being added as an expansion card.
