3. RAM footprint: The minimum amount of RAM which an OS or other program takes; this figure gives one an idea of how much will be left for other applications. How actively this RAM is used is another matter entirely. Recent tendencies to featuritis and software bloat can expand the RAM footprint of an OS to the point of making it nearly unusable in practice. [This problem is, thankfully, limited to operating systems so stupid that they don't do virtual memory -- ESR]

An example of an elliptical footprint with a reception area of Germany, Austria and Switzerland. The ellipses necessary antenna diameter for receiving in cm is indicated.

The footprint of a communications satellite is the ground area that its transponders offer coverage, and determines the satellite dish diameter required to receive each transponder's signal. There is usually a different map for each transponder (or group of transponders) as each may be aimed to cover different areas of the ground.

Footprint maps usually show either the estimated minimal satellite dish diameter required or the signal strength in each area measured in dBW.
