Exclusive

From Wikipedia, the free encyclopedia

  • In the description of a mathematical set, the term exclusive denotes that the endpoints of a range are not included within the set. For example, "the integers -2 to 2 exclusive" refers to the set {-1,0,1}; the endpoints, -2 and 2, are excluded. The term is generally applied to discrete elements.
  • In Boolean logic the exclusive or operator refers to exclusive disjunction, which has a true value if either but not both arguments are true. Distinct from inclusive or (or simply or), which is true if either or both arguments are true.
  • In marketing, "exclusive" can refer to products that are only available from select distributors or retailers, or only at a particular event.
  • In journalism, "exclusive" can refer to information provided to or available from only one news outlet, such as an interview or photograph.
