Final answer:
An icon is a visual representation of an application or function on a digital screen. Advantages of digital image capture over film include immediacy, storage, and no need for physical film. Directional terms like right and left are crucial in different contexts for guidance.
Step-by-step explanation:
An icon is a graphical symbol on a device's screen that represents an application, function, or data. On a digital platform, you might see a playback button icon which typically looks like a right-facing triangle, and a delete function icon, often represented by a trash can or an 'X'. The icons and short-codes within a book are meant to guide you to related digital resources quickly. For example, a picture of a playback button could have a short-code that, when entered online, takes you directly to a video.
Regarding digital image capture, some advantages over film photography may include the immediate availability of images, the ease of storage, and the lack of need for physical film, which provides economic and environmental benefits. This is important because these advantages reflect the shift in how we capture and manage photographs in the digital age.
The context of seating arrangements in an orchestra or event is also discussed to illustrate the practicality of directional terms such as right and left when navigating social situations or following instructions.
