1. The degree to which a system, subsystem, or equipment is operable and in a committable state at the start of a mission, when the mission is called for at an unknown, i. E. , a random, time. Note 1: The conditions determining operability and committability must be specified. Note 2: Expressed mathematically, availability is 1 minus the unavailability. 2. The ratio of (a) the total time a functional unit is capable of being used during a given interval to (b) the length of the interval. Note 1: An example of availability is 100/168 if the unit is capable of being used for 100 hours in a week. Note 2: Typical availability objectives are specified in decimal fractions, such as 0. 9998. 3. Timely, reliable access to data and information services for authorized users. 4. The prevention of denial of service. 5. The property of being accessible and useable upon demand by an authorized entity. 6. The prevention of the unauthorized withholding of information or resources. 7. The property of an object being accessible and usable upon demand by an authorized subject.

1. The complete set of signals, usually electromagnetic or acoustic, received from a source such as an infrared object, a radio or radar transmitter, an aircraft, or a ship. Note: Signatures may consist of analog or digital signals, or both, and may be analyzed to indicate the nature of their source and assist in its recognition. 2. The attributes of an electromagnetic or acoustic wave that has been reflected from or transmitted through an object and contains information indicating the attributes of the object. Note: In this context, "objects" may include man-made objects or natural ones, the latter including both those that are well defined, e. G. , terrain, and those that are not, e. G. , weather phenomena. See also digital signature.

A radio path between two points, called a radio link. 4. In communications, a general term used to indicate the existence of communications facilities between two points. 5. A conceptual circuit, i. E. , logical circuit, between two users of a network, that enables the users to communicate, even when different physical paths are used. Note 1: In all cases, the type of link, such as data link, downlink, duplex link, fiber optic link, line-of-sight link, point-to-point link, radio link and satellite link, should be identified. Note 2: A link may be simplex, half-duplex, or duplex. 6. In a computer program, a part, such as a single instruction or address, that passes control and parameters between separate portions of the program. 7. In hypertext, a logical connection between discrete units of data, or a hypertext connection between Web pages. Synonyms (in this sense) hotlink, hyperlink.

(COMSEC) The capability and opportunity to gain detailed knowledge of or to alter information or material. 4. (AIS) The ability and means to communicate with (i. E. , input to or receive output from,) or otherwise make use of any information, resource, or component in an AIS. Note : An individual does not have "access" if the proper authority or a physical, technical, or procedural measure prevents him/her from obtaining knowledge or having an opportunity to alter information, material, resources, or components. 5. An assigned portion of system resources for one data stream of user communications or signaling. 6. An opportunity to make use of an information-system (IS) resource. 7. Condition where the potential exists for information to flow between entities. 8. A specific type of interaction between a subject and an object that results in the flow of information from one to the other. 9 A specific type of interaction between a subject and an object that results in the flow of information from one to the other. Possible information flows include the transfer of attributes pertaining to that object, the transfer of data pertaining to that object, or the fact of existence of that object. 10. A specific type of interaction between a subject and an object that results in the flow of information from one to the other.
