The models of computation generally considered to be distributed are process models, in which computational activity is represented as the con-current execution of sequential processes. Other models, such as Petri nets [Thi85], are usually not studied under the title of distributed comput-ing, even though they may be used to model spatially distributed systems. 1 MEIJE - Concurrency, Synchronization and Real-time Programming . CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): A distributed application runs as a collection of processes on a distributed system. The legacy system acts as a server in its own right with a graphical interface implemented on a client. • We recognize that a change in the level of an explanatory variable may have behavioral implications beyond the time period in which it occurred.

In computer science, and more specifically in computability theory and computational complexity theory, a model of computation is a model which describes how an output of a mathematical function is computed given an input. For example, grid computing, studied in the previous section, is a form of distributed computing where the nodes may belong to different administrative domains.
