Vector graphics is the use of polygons to represent images in computer graphics.

Vector graphics are based on vectors, which lead through locations called control points or nodes.

In computing, an icon is a pictogram or ideogram displayed on a computer screen in order to help the user navigate a computer system or mobile device.

The icon itself is a quickly comprehensible symbol of a software tool, function, or a data file, accessible on the system and is more like a traffic sign than a detailed illustration of the actual entity it represents.

It can serve as an electronic hyperlink or file shortcut to access the program or data.

The user can activate an icon using a mouse, pointer, finger, or recently voice commands.

Their placement on the screen, also in relation to other icons, may provide further information to the user about their usage.

In activating an icon, the user can move directly into and out of the identified function without knowing anything further about the location or requirements of the file or code.

Freeware is software that is available for use at no monetary cost.

In other words, while freeware may be used without payment it is most often proprietary software, as usually modification, re-distribution or reverse-engineering without the author's permission is prohibited.

Two historic examples of freeware include Skype and Adobe Acrobat Reader.

There is no agreed set of rights or a license or an EULA which would define "freeware" unambiguously; every Freeware publisher defines their own rules for their Freeware.

For instance, redistribution of Freeware by third-parties is often permitted but there is a significant portion of Freeware which prohibits redistribution.
