Discrete

1. Separate; distinct; individual; non-continuous.
2. That can be perceived individually and not as connected to, or part of something else.
3. (electrical engineering) Having separate electronic components, such as individual diodes, transistors and resisters, as opposed to integrated circuitry.
4. (audio engineering) Having separate and independent channels of audio, as opposed to multiplexed stereo or quadraphonic, or other multi-channel sound.
5. (topology) Having each singleton subset open: said of a topological space or a topology.
6. Disjunctive; containing a disjunctive or discretive clause.

Although cognate and identical in the Middle English period, the term has become distinct from discreet.
