In computing, "serial" or "sequential" refers to a method of processing data where tasks are completed one after another in a specific order. This approach contrasts with parallel processing, where multiple tasks are executed simultaneously. Serial processing is often simpler to implement and understand, making it suitable for tasks that depend on the completion of previous steps. In programming, serial execution can be seen in algorithms that require a sequence of operations, such as sorting algorithms or data processing tasks. While it may be slower for large datasets, it ensures that each step is completed before moving on to the next, maintaining data integrity.
