Parallel processing refers to the simultaneous execution of multiple tasks using a single processor, where the tasks are divided into smaller sub-tasks and executed in a sequential manner. Truly parallel processing, on the other hand, involves the simultaneous execution of multiple tasks using multiple processors, where each processor works independently on its own set of tasks. In other words, parallel processing may involve time-sharing or interleaving of tasks on a single processor, while truly parallel processing involves the simultaneous execution of tasks on multiple processors.
