End user

In product development, an end user (sometimes end-user) is a person who ultimately uses or is intended to ultimately use a product. The end user stands in contrast to users who support or maintain the product, such as sysops, system administrators, database administrators, or technicians. End users typically do not possess the technical understanding or skill of the product designers, a fact that it is easy for designers to forget or overlook, leading to features with which the customer is dissatisfied. In information technology, end users are not customers in the usual sense—they are typically employees of the customer.

Certain American defense-related products and information require export approval from the United States Government under the ITAR and EAR. In order to obtain a license to export, the exporter must specify both the end user and end use using an end-user certificate.

In End-User License Agreements (EULAs), the end user is distinguished from the value-added reseller that installs the software or the organization that purchases and manages the software.

User (computing)

A user is a person who uses a computer or network service. Users generally use a system or a software product without the technical expertise required to fully understand it.Power users use advanced features of programs, though they are not necessarily capable of computer programming and system administration.

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, screen name (or screenname), nickname (or nick) and handle, which is derived from the identical Citizen's 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 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. This abstraction is primarily useful in designing the user interface, and refers to a relevant subset of characteristics that most expected users would have in common.

End-user (disambiguation)

Conclusion (music)

In music, the conclusion is the ending of a composition and may take the form of a coda or outro.

Pieces using sonata form typically use the recapitulation to conclude a piece, providing closure through the repetition of thematic material from the exposition in the tonic key. In all musical forms other techniques include "altogether unexpected digressions just as a work is drawing to its close, followed by a return...to a consequently more emphatic confirmation of the structural relations implied in the body of the work."

End (graph theory)

In the mathematics of infinite graphs, an end of a graph represents, intuitively, a direction in which the graph extends to infinity. Ends may be formalized mathematically as equivalence classes of infinite paths, as havens describing strategies for pursuit-evasion games on the graph, or (in the case of locally finite graphs) as topological ends of topological spaces associated with the graph.

Ends of graphs may be used (via Cayley graphs) to define ends of finitely generated groups. Finitely generated infinite groups have one, two, or infinitely many ends, and the Stallings theorem about ends of groups provides a decomposition for groups with more than one end.

Definition and characterization

Ends of graphs were defined by Rudolf Halin (1964) in terms of equivalence classes of infinite paths. A ray in an infinite graph is a semi-infinite simple path; that is, it is an infinite sequence of vertices v₀, v₁, v₂, ... in which each vertex appears at most once in the sequence and each two consecutive vertices in the sequence are the two endpoints of an edge in the graph. According to Halin's definition, two rays r₀ and r₁ are equivalent if there is another ray r₂ (not necessarily different from either of the first two rays) that contains infinitely many of the vertices in each of r₀ and r₁. This is an equivalence relation: each ray is equivalent to itself, the definition is symmetric with regard to the ordering of the two rays, and it can be shown to be transitive. Therefore, it partitions the set of all rays into equivalence classes, and Halin defined an end as one of these equivalence classes.
