Serial processing in a computer is when instructions are processed one after another, in order, until the job is done. In serial processing, only one processor is used, which processes one program at a time and executes one instruction at a time. A real$-$world example is customers standing in a queue and waiting to check out at a grocery store where there is only one cashier. Parallel processing is a type of processing in which multiple tasks are completed at a time by different processors. A real$-$world example is multiple queues of customers standing to check out at a grocery store with multiple cashiers. Watch this video for more information.

Respond to the following:

Provide $2$ of your own examples, $1$ for serial processing and $1$ for parallel processing, and explain why each example is either serial or parallel processing.

For the grocery store examples provided in the assignment description: there is one cashier handling multiple customer queues by taking one customer from each queue, in sequence. Is this parallel processing? Why or why not?

What do you see as the advantages and disadvantages of serial and parallel processing?
