Sequential Processing
Sequential processing is a fundamental computing concept where tasks or instructions are executed one after another in a strict, linear order, with each step completing before the next begins. It is the default mode of operation in single-threaded programs and traditional von Neumann architecture computers, ensuring deterministic and predictable execution flow. This approach contrasts with parallel or concurrent processing, where multiple tasks can be handled simultaneously or in overlapping timeframes.
Developers should understand sequential processing as it underpins basic programming logic, algorithm design, and debugging in environments like single-core systems or when using languages like Python (without concurrency features). It is essential for scenarios requiring strict order dependencies, such as data processing pipelines, financial transactions, or any task where race conditions must be avoided. Learning this concept helps in optimizing performance by identifying bottlenecks and when to transition to parallel techniques.
