(3) The exact part of an icon or screen pointer that is sensitive to selection. A hotspot may be part of a larger image. For example, an image may have several hotspots, one for each of its components. When clicked, a greater explanation of the component is produced. Where hotspots begin and end determine how easy they are to select.

The screen pointer also has a hotspot, which is a small number of pixels that make contact with the icon's hotspot. For example, the tip of an arrow or finger pointer or the crosspoint of an X-shaped pointer may be the pointer's hotspot.

(4) A network node that is processing at its maximum or is backlogged due to an excessive number of transactions.
