Single Process Architecture
Single Process Architecture is a software design pattern where an application runs as a single process, handling all tasks sequentially within that process. It is a straightforward approach where the entire program executes in one memory space, making it simple to implement and debug. This architecture is common in small-scale applications, scripts, or legacy systems where concurrency is not required.
Developers should use Single Process Architecture for simple applications, prototypes, or tools where performance and scalability are not critical, as it reduces complexity and overhead. It is ideal for command-line utilities, batch processing scripts, or small desktop applications that do not need to handle multiple simultaneous requests. Learning this helps understand basic program flow before moving to more complex multi-process or distributed architectures.
