But, when it comes to graphics or designing it is the design or use of signs and symbols. And, yes, it also refers to signs that are considered a group. Different types of graphic symbols were developed as part of a system for various facilities in public railway or bus station environments.

In digital design it means a different way of advertising. In the 1970s the concept emerged; however, before the advent of commercial advertising almost everything was pre-recorded. Now these technological advertisers are used effectively in business marketing.

Having these digital advertisers allows large business organizations to make use of electronic screens for advertising. It is a great way to convey your information, advertisements or any other information to your students, colleagues, customers and the general public.

In very simple terms, this digital type of file can start out as a PowerPoint presentation and then, using a digital software package, it can be shown on an LCD monitor, including the large format, large plasma screen, projectors and multiple monitors. The locations where they may be used is almost endless; a shopping mall, airport, restaurant, on highways giving road and traffic conditions, along with numerous other locations.

Obviously, signs exist to communicate information, but surprisingly in many communities the sign and print design industry and planning profession do not have an effective means of communicating with one another. Signage from the local government point of view is motivated by the need to ensure public safety and at the same time negate visual impacts of the signs in a community. It is actually called "visual clutter" and it is difficult for communities to come to a compromise; the need for signs versus the visual impact.

While any collection of correlated signs can be considered one of these systems, it is usually used to refer to a group of signs with coherent custom designs and purpose. Frequently, significant effort is put into creating a presentation that takes human reactive responses to color and typefaces into consideration.

Aside from individual signs and groups of other signs, there is also what is referred to as signage systems. An example of this type of system would include subway signs and airport signs. They differ from other systems as they are used to guide peoples' passage through an area. They normally consist of signs, maps, arrows and many are color coded with pictograms.
