prosessiohjelmia

Prosessiohjelmia, known in English as process software or process-oriented programming, refers to a programming paradigm that focuses on the execution and management of processes. In this paradigm, the primary unit of computation is a process, which is an instance of a running program. Processes are distinct entities that can operate independently, communicate with each other, and share or not share resources as defined by the operating system.

The core idea behind prossesiohjelmia is to model concurrent and distributed systems as a collection of interacting processes. This contrasts with other paradigms where the focus might be on threads within a single process or on objects and their interactions. Communication between processes is a key aspect, often facilitated through mechanisms like message passing, shared memory, or inter-process communication (IPC) channels.

Prosessiohjelmia is particularly well-suited for building systems where parallelism and distribution are inherent requirements, such as operating systems, network servers, and parallel computing applications. By treating processes as fundamental building blocks, developers can manage complex asynchronous operations and achieve a higher degree of fault isolation, as the failure of one process typically does not affect others. Languages and systems that support this paradigm often provide explicit constructs for process creation, termination, and communication.
