Concurrency (computer science)In computer science, concurrency is the ability of different parts or units of a program, algorithm, or problem to be executed out-of-order or in partial order, without affecting the outcome. This allows for parallel execution of the concurrent units, which can significantly improve overall speed of the execution in multi-processor and multi-core systems. In more technical terms, concurrency refers to the decomposability of a program, algorithm, or problem into order-independent or partially-ordered components or units of computation.

Join and meetIn mathematics, specifically order theory, the join of a subset of a partially ordered set is the supremum (least upper bound) of denoted and similarly, the meet of is the infimum (greatest lower bound), denoted In general, the join and meet of a subset of a partially ordered set need not exist. Join and meet are dual to one another with respect to order inversion. A partially ordered set in which all pairs have a join is a join-semilattice. Dually, a partially ordered set in which all pairs have a meet is a meet-semilattice.
Haptic communicationHaptic communication is a branch of nonverbal communication that refers to the ways in which people and animals communicate and interact via the sense of touch. Touch is the most sophisticated and intimate of the five senses. Touch or haptics, from the ancient Greek word haptikos is extremely important for communication; it is vital for survival. Touch is the first sense to develop in the fetus. The development of an infant's haptic senses and how it relates to the development of the other senses such as vision has been the target of much research.

The probability that an item will operate satisfactorily at a given point in time when used under stated conditions in an ideal support environment.
