A type of web browser associated with the Mac OS platform.

Keyword(s):

Satellite imaging

Many satellites transmit photographic images which can be used in a variety of ways, e.g. tracking the progress of a hurricane. Images can be received, stored and viewed on a computer.

Scanner

Works like a small photocopier, but the image can be displayed on a computer screen, saved to disc or printed out. Most scanners will take up to A4 size.

Scene

To organize a document thematically, you can use scenes. For example, you might use separate scenes for an introduction, a loading message, and credits.

Note: You cannot use scenes in a screen-based document.

When you publish a Flash document that contains more than one scene, the scenes in the document play back in the order they are listed in the Scene panel in the Flash document. Frames in the document are numbered consecutively through scenes. For example, if a document contains two scenes with ten frames each, the frames in Scene 2 are numbered 11-20.

You can add, delete, duplicate, rename, and change the order of scenes.

To stop or pause a document after each scene, or to let users navigate the document in a nonlinear fashion, you use actions.

Search Engine

A search engine is a program designed to help find information stored on a computer system such as the World Wide Web, inside a corporate or proprietary network or a personal computer.

Keyword(s):

Search Engines

Permits searching of documents and databases accessible on the Internet. Search engines can be set up to search only content within one Web site or to search the entire Internet. Many search engine developers have their own web sites such as Lycos and Alta Vista. In addition to search engines there are index sites such as Yahoo, where links to Web sites are organized into categories so that you can browse categories rather than guessing at search terms.

Keyword(s):

Search engine/facility

Most CD-ROMs and the Internet have search engines. These are facilities which allow the user to search for information without having to look through a whole index or catalogue and are generally based on keywords and logical operators.

Security

The protection of information assets through the use of technology, processes, and training.

Keyword(s):

Sensing technology (including remote sensing)

Equipment which can be connected to a computer, and which will record and display information from sensors, e.g. light, sound, movement or temperature. Some sensing equipment can be used to collect data away from the computer, but be linked to the computer later to display the recordings made.

Server

A powerful computer which is central to many networks. The server will control access to the network, and will store most files centrally. Internet web pages are held on the service providers web server.

Shape

Shape is a 2D or implied 2D area defined by line or changes in value and/or colour.

Shape Tween

By tweening shapes, you can create an effect similar to morphing, making one shape appear to change into another shape over time. Flash can also tween the location, size, and color of shapes.

Simulations

Computer programs which simulate real or imaginary scenarios. Often used to simulate events that would normally be impossible, difficult or dangerous.

Slicing

In object-oriented programming, slicing is an operation to slice off a target value by size of the base type, thus extra parts will be gone. This is not the same as array slicing, however it does have similar characteristics.

Keyword(s):

Snap to Grid

The Snap to Grid tool allows user to precisely position their elements on the Flash page.

Sound

There are two types of sounds in Flash: event sounds and stream sounds. An event sound must download completely before it begins playing, and it continues playing until explicitly stopped. Stream sounds begin playing as soon as enough data for the first few frames has been downloaded.

Speech input/output

Many computer programs, especially word processors, can read text audibly and can convert spoken words into text.
