'''Distributed operating system''' is a decentralized [[operating system]], with its functionality disseminated across multiple, independent processing entities. The system is able to project a complete, consistent, and transparent abstraction; presenting a façade, understood by a user in a familiar centralized context. This abstraction hides the system's distributed nature, not simply separating a user from inherent complexity, but preventing its indication altogether.

DOS is an OS
<br />{{pad|2em}} isolates and manages lower-level complexities of Hware and resources
<br />{{pad|2em}} organizes and presents higher-level interfaces of Hware and resources
<br />{{pad|2em}} OS is the complex mapping of these abstractions to interfaces
<br />{{pad|2em}} presents itself as unified and simplified service to these mappings
<br />{{pad|2em}} DOS, as such, appears no different than would a centralized OS
<br />{{pad|2em}} in fact, much different
<br />
<br />{{pad|2em}} OS most often depicted as a discrete organizational container, positioned independently between Hware and app/programmer/etc.
<br />{{pad|2em}} DOS, presented in a similar fashion would incorporate Hware within its organizational container
<br />{{pad|4em}} it is the Hware that exhibits differing degrees of geo-spatial separation; DOSs distributed quality
<br />{{pad|4em}} to provide consistent and unified interface to this abstraction, Hware must be inclusive to the idea of ODS
<br />
<br />{{pad|2em}} This is a very important distinction, as
<br />{{pad|4em}} it will serve differentiate DOS from other decentralized OSs (later)
<br />{{pad|4em}} it makes possible many additional and beneficial services (described in a later section)
<br />{{pad|6em}} it is solely the attribute of Hware separation that allows these benefits
<br />{{pad|6em}} it is the complex orchestrated utilization of Hware separation that instantiates these benefits
<br />
<br />{{pad|2em}} In approach to describing the nature of DOS, will also differentiate from other decentralized OSs
<br />{{pad|2em}} A Network OS is decentralized, but not distributed (as seen below)
<br />{{pad|2em}} OS constituent element organization: decentralized vs. distributed
<br />{{pad|4em}} three tightly interrelated aspects to this organization:
<br />{{pad|6em}} organizational hierarchy, degree of interconnection, sphere of control
<br />{{pad|4em}} organizational hierarchy:
<br />{{pad|6em}} centralized:
<br />{{pad|8em}} dictatorship - one level
<br />{{pad|8em}} all entities report directly to one higher-level entity
<br />{{pad|6em}} decentralized:
<br />{{pad|8em}} federated - one or more levels
<br />{{pad|8em}} any given sub-level's entities reporting directly to next higher-level entity
<br />{{pad|6em}} distributed:
<br />{{pad|8em}} autonomous - no levels required
<br />{{pad|8em}} all entities reporting directly/indirectly to an appointed coordinator
<br />{{pad|4em}} degree of interconnection:
<br />{{pad|6em}} centralized:
<br />{{pad|8em}} single direct connection
<br />{{pad|10em}} balloons on a string
<br />{{pad|6em}} decentralized:
<br />{{pad|8em}} single direct/indirect connection
<br />{{pad|10em}} corporate org-chart (no dotted lines)
<br />{{pad|10em}} twigs, limbs, branches of a tree
<br />{{pad|6em}} distributed:
<br />{{pad|8em}} multiple direct/indirect connections possible
<br />{{pad|10em}} string art, spiro-graph (completely connected)
<br />{{pad|10em}} spider web (closest neighbors)
<br />{{pad|10em}} interstate system (suited to purpose)
<br />{{pad|4em}} sphere of control:
<br />{{pad|6em}} centralized:
<br />{{pad|8em}} direct and absolute
<br />{{pad|6em}} decentralized:
<br />{{pad|8em}} shared by level, through delegation and follow-up
<br />{{pad|6em}} distributed:
<br />{{pad|8em}} collective, usually through mutual agreement
<br />
<br />{{pad|2em}} DOS is an OS with a unique set of constitutional characteristics
<br />{{pad|4em}} providing opportunity for an exceptional array of additional and extended services
<br />{{pad|4em}} while overcoming extreme quantities and degrees of complexity in the process
