Parallel processing of two independent processes is analogized to a single one with two parallel threads. How should we proceed given the existing circumstances?

In the same way as three loop iterations on a parallel computer is like baking a cake, so too is the process of making a cake. Determine and describe instances of data-level and task-level parallelism in the baking process.

How precisely may DMA help with the system's concurrent nature? In what particular ways does it make hardware design more difficult?

It was pointed out that two advantages of using multiple threads within a process are that (1) less work is involved in creating a new thread within an existing process than in creating a new process, and (2) communication among threads within the same process is simplified. Is it also the case that a mode switch between two threads within the same process involves less work than a mode switch between two threads in different processes?
