ad hoc is a Latin phrase meaning "for this". It generally signifies a solution designed for a specific problem or task, non-generalizable, and not intended to be able to be adapted to other purposes. Common examples are organizations, committees, and commissions created at the national or international level for a specific task. In other fields the term may refer, for example, to a military unit created under special circumstances, a tailor-made suit, a handcrafted network protocol, or a purpose-specific equation. ad hoc can also mean makeshift solutions, shifting contexts to create new meanings, inadequate planning, or improvised events.
In science and philosophy, ad hoc means the addition of extraneous hypothesis to a theory to save it from being falsified. ad hoc hypotheses compensate for anomalies not anticipated by the theory in its unmodified form. Scientists are often skeptical of theories that rely on frequent, unsupported adjustments to sustain them. ad hoc hypotheses are often characteristic of pseudoscientific subjects such as homeopathy.
In military, ad hoc units are created during unpredictable situations, when the cooperation between different units is needed for fast action.
The term ad hoc networking typically refers to a system of network elements that combine to form a network requiring little or no planning.
