User (telecommunications)
In telecommunications, a user is a person, organization, or other entity that employs the services provided by a telecommunication system, or by an information processing system, for transfer of information. A user functions as a source or final destination of user information, or both. A user ''may'' also be the subscriber, i.e. the customer paying for the service. User is also a person or process accessing an AIS by direct connections (e.g., via terminals) or indirect connections. "Indirect connection" relates to persons who prepare input data or receive output that is not reviewed for content or classification by a responsible individual.

Telecommunications
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded d ...

Information
Information is an abstract concept that refers to that which has the power to inform. At the most fundamental level information pertains to the interpretation of that which may be sensed. Any natural process that is not completely random, and any observable pattern in any medium can be said to convey some amount of information. Whereas digital signals and other data use discrete signs to convey information, other phenomena and artifacts such as analog signals, poems, pictures, music or other sounds, and currents convey information in a more continuous form. Information is not knowledge itself, but the meaning that may be derived from a representation through interpretation. Information is often processed iteratively: Data available at one step are processed into information to be interpreted and processed at the next step. For example, in written text each symbol or letter conveys information relevant to the word it is part of, each word conveys information rele ...

User Information
User information is information transferred across the functional interface between a source user and a telecommunications system for delivery to a destination user. In telecommunications systems, user information includes user overhead information Overhead information is digital information transferred across the functional interface Interface or interfacing may refer to: Academic journals * ''Interface'' (journal), by the Electrochemical Society * '' Interface, Journal of Applied Lin ....

Subscriber
The subscription business model is a business model in which a customer must pay a recurring price at regular intervals for access to a product or service. The model was pioneered by publishers of books and periodicals in the 17th century, and is now used by many businesses, websites and even pharmaceutical companies in partnership with the government. Subscriptions Rather than selling products individually, a subscription offers periodic (daily, weekly, bi-weekly, monthly, semi-annual, yearly/annual, or seasonal) use or access to a product or service, or, in the case of performance-oriented organizations such as opera companies, tickets to the entire run of some set number of (e.g., five to fifteen) scheduled performances for an entire season. Thus, a one-time sale of a product can become a recurring sale and can build brand loyalty. Industries that use this model include mail order book sales clubs and music sales clubs, private web mail providers, cable television, satell ...

Customer
In sales, commerce, and economics, a customer (sometimes known as a client, buyer, or purchaser) is the recipient of a good, service, product or an idea - obtained from a seller, vendor, or supplier via a financial transaction or exchange for money or some other valuable consideration. Etymology and terminology Early societies relied on a gift economy based on favours. Later, as commerce developed, less permanent human relations were formed, depending more on transitory needs rather than enduring social desires. Customers are generally said to be the purchasers of goods and services, while clients are those who receive personalized advice and solutions. Although such distinctions have no contemporary semantic weight, agencies such as law firms, film studios, and health care providers tend to prefer '' client'', while grocery stores, banks, and restaurants tend to prefer '' customer'' instead. Clients The term client is derived from Latin ''clients'' or ''care'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automated Information System
An automated information system (AIS) is an assembly of computer hardware, software, firmware, or any combination of these, configured to accomplish specific information-handling operations, such as communication, computation, dissemination, processing, and storage of information. Included are computers, word processing systems, networks, or other electronic information handling systems, and associated equipment. Management information systems are a common example of automated information systems. An example of this is an industrial robot. Also an Automated Information System (AIS) refers to any piece of equipment or interconnected system of equipment utilized in the automated collection, storage, manipulation, management, movement, control, display, switching, interchange, transmission, or receiving of data, and includes computer software, firmware, and hardware. Computers, word processing systems, networks, or other electronic information handling systems, as well as accompany ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Information Systems Security Glossary
Committee on National Security Systems Instruction No. 4009, National Information Assurance Glossary, published by the United States federal government, is an unclassified glossary of Information security terms intended to provide a common vocabulary for discussing Information Assurance concepts. The glossary was previously published as the National Information Systems Security Glossary (NSTISSI No. 4009) by the National Security Telecommunications and Information Systems Security Committee (NSTISSC). Under Executive Order (E.O.) 13231 of October 16, 2001, Critical Infrastructure Protection in the Information Age, the President George W. Bush redesignated the National Security Telecommunications and Information Systems Security Committee (NSTISSC) as the Committee on National Security Systems (CNSS). The most recent version was revised April 26, 2010. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User (computing)
A user is a person who utilizes a computer or network service. A user often has a user account and is identified to the system by a username (or user name). Other terms for username include login name, screenname (or screen name), account name, nickname (or nick) and handle, which is derived from the identical citizens band radio term. Some software products provide services to other systems and have no direct end users. End user End users are the ultimate human users (also referred to as operators) of a software product. The end user stands in contrast to users who support or maintain the product such as sysops, database administrators and computer technicians. The term is used to abstract and distinguish those who only use the software from the developers of the system, who enhance the software for end users. In user-centered design, it also distinguishes the software operator from the client who pays for its development and other stakeholders who may not direct ...
