Typography
In typography, tracking is the process of uniformly increasing or decreasing the space between all glyphs (letters) in a block of text. It is commonly confused with kerning, but these are two separate concepts. Tracking is sometimes called character spacing or letter spacing, especially in reference to computer typesetting. A related concept is that of word spacing, which uniformly increases or decreases the space between words.
Logistics
In logistics, tracking is the process of uniformly building a track of objects that are forwarded to, processed for, applied in or disposed of usage. The obtained track hence is a map depicted or coordinates listed in real-time of the reckoned locations of the respective object.
Tracking originally is subject of reckoning, concerning setting up a track on other objects momentarily viewed from the observer's own location. A related concept is that of tracing, which uniformly describes the process of retrospectively generating a trace.
Tracking should not be used synonymously to tracing in logistics. Both terms are used in conjunction as Tracking and Tracing for imposing control on performing services of logistics.
