1. Identity Domain
   A set of systems that includes a source system and a collection of consuming systems. Each system in a given identity domain uses the same unique identifier. The operational server enables the integration of information across multiple identity domains.

   A set of systems that includes a source system and a collection of consuming systems. Each system in a given identity domain uses the same unique identifier. The operational server enables the integration of information across multiple identity domains.
2. Identity Management (IdM)
   Processes and policies involved in managing the lifecycle and value, type, and optional metadata of attributes in identity known in a particular identity domain.

   Identity management (IdM) is the task of controlling information about users on computers. Such information includes information that authenticates the identity of a user, and information that describes information and actions they are authorized to access and/or perform. It also includes the management of descriptive information about the user and how and by whom that information can be accessed and modified. Managed entities typically include users, hardware and network resources and even applications. Digital identity is an entity's online presence, encompassing personal identifying information (PII) and ancillary information. See OECD and NIST guidelines on protecting PII. It can be interpreted as the codification of identity names and attributes of a physical instance in a way that facilitates processing.
3. Identity of Things (IDoT)
   The Identity of Things (IDoT) is an area of endeavor that involves assigning unique identifiers (UID) with associated metadata to devices and objects (things), enabling them to connect and communicate effectively with other entities over the Internet.

   The metadata associated with the UID collectively defines the identity of an endpoint. Identity of things is an essential component of the Internet of Things (IoT), in which almost anything imaginable can be addressed and networked for exchange of data online. In this context, a thing can be any entity -- including both physical and logical objects -- that has a unique identifier and the ability to transfer data over a network.
4. Identity Verification
   A process to determine that presented identity information associated with a particular entity is applicable for the entity to be recognized in a particular identity domain at some point in time.

   An Identity verification service is used by businesses to ensure that users or customers provide information that is associated with the identity of a real person. The service may verify the authenticity of physical identity documents such as a drivers license or passport, called documentary verification, or may verify identity information against authoritative sources such as a credit bureau or government data, called non-documentary verification. Identity verification service is used both online and in person to verify identity. These services are used by some social networking sites, Internet forums, dating sites and wikis to stop sockpuppetry, underage signups, spamming and illegal activities like harassment, scams, and money laundering. These services are required to establish bank accounts and other financial accounts in many jurisdictions. In financial industries, verifying identity is often required by regulation known as Know Your Customer or Customer Identification Program (CIP). In the US, one of the many bodies regulating these procedures is the Financial Crimes Enforcement Network (FinCEN). A non-documentary identity verification requires the user or customer to provide personal identity data which is sent to the identity verification service. The service checks public and private databases for a match on the information provided. Optionally, knowledge-based authentication questions can be presented to the person providing the information to ensure that he or she is the owner of the identity. An identity "score" is calculated, and the identity of the user or customer is either given the "verified" status, or not, based on the score.

    The industrial, scientific, and medical radio band refers to a group of radio bands or parts of the radio spectrum that are internationally reserved for the use of radio frequency (RF) energy intended for scientific, medical, and industrial requirements rather than for communications.

    The use of ISM equipment generates electromagnetic interference that interrupts radio communications that make use of the same frequency. Therefore, this equipment was restricted to specific frequency bands. Generally, the communication equipment that operates in these bands should tolerate the interference created by ISM equipment, and therefore users do not have any regulatory protection from the use of ISM equipment. In the US, the ISM bands are 915MHz, 2.4 GHz, and 5.5 GHz, whereas 2.4 GHz is the global unlicensed frequency and has increasing amounts of interference.

    Interoperability is the ability of a system or a product to work with other systems or products without special effort on the part of the customer. It becomes a quality of increasing importance for information technology products as the concept that "The network is the computer" becomes a reality.

    Interoperability becomes a quality of increasing importance for information technology products as the concept that "The network is the computer" becomes a reality. For this reason, the term is widely used in product marketing descriptions. A good example of the first approach is the set of standards that have been developed for the World Wide Web. These standards include TCP/IP, Hypertext Transfer Protocol, and HTML. The second kind of interoperability approach is exemplified by the Common Object Request Broker Architecture (CORBA) and its Object Request Broker (ORB). Compatibility is a related term. A product is compatible with a standard but interoperable with other products that meet the same standard (or achieve interoperability through a broker).
