  • information architecture

    In technical writing, information architecture is the set of ideas about how all information in a given context should be treated philosophically and, in a general way, how it should be organized.

  • information life cycle management (ILM)

    Information life cycle management (ILM) is a comprehensive approach to managing the flow of an information system's data and associated metadata from creation and initial storage to the time when it becomes obsolete and is deleted.

  • intelligent switch

    An intelligent switch is a high-level storage area network (SAN) routing switch that provides features such as storage virtualization, quality of service (QoS), remote mirroring, data sharing, protocol conversion, and advanced security.

  • International Standard Recording Code (ISRC)
