Control as Concurrent Tasks

The expression control as simultaneous task means applying control for those events of object which can happen simultaneously. An object can be implemented as a task in programming language or the operating system. This is the most common approach of concurrency controls. With this you can preserve inherent concurrency of real objects. You can implement events as inter-task calls using facilities of language or the operating system.

So far as OO programming languages are concerned, there are some languages for example Concurrent Pascal or simultaneous C++, which support concurrency, but application of such languages in production environments is still restricted. Ada language also supports concurrency, provided that objects are equated with an Ada task, although run-time cost is very high. The main object oriented languages do not yet support concurrency.
