• In information systems, an information system consists of three components: human, task, application system. In this view, information is defined in terms of the three levels of semiotics. Data which can be automatically processed by the application system corresponds to the syntax-level. In the context of an individual who interprets the data they become information, which correspond to the semantic-level. Information becomes knowledge when an individual knows (understands) and evaluates the information (e.g., for a specific task). This corresponds to the pragmatic-level.

• In general systems theory, an information system is a system, automated or manual, that comprises people, machines, and/or methods organized to collect, process, transmit, and disseminate data that represent user information.

• In rough set theory, an information system is an attribute-value system.

• In telecommunications, an information system is any telecommunications and/or computer related equipment or interconnected system or subsystems of equipment that is used in the acquisition, storage, manipulation, management, movement, control, display, switching, interchange, transmission, or reception of voice and/or data, and includes software, firmware, and hardware.

• In computer security, an information system is described by five objects (Canal 2004):
  • Structure:
    • Repositories, which hold data permanent or temporarily, such as buffers, RAM, hard disks, cache, etc.
    • Interfaces, which exchange information with the non-digital world, such as keyboards, speakers, scanners, printers, etc.
    • Channels, which connect repositories, such as buses, cables, wireless links, etc. A Network is a set of logical or physical channels.
  • Behaviour:
    • Services, which provide value to users or to other services via messages interchange.
    • Messages, which carries a meaning to users or services.
