4.3 Parallel and Distributed Computing

__________ computing is a computational model in which operations are performed in order one at a time.

• Parallel

• Sequential

• Distributed

_______ computing is a computational model where the program is broken into multiple smaller sequential computing operations.

• Parallel

• Distributed

• Sequential

• Iterated

_______ computing is a computational model in which multiple devices are used to run a program.

• Distributed

• parallel

• Sequential

• Drake

Comparing efficiency of solution can be done by comparing the time it takes them to perform the same task.

• True

• False

A sequential solution takes longer than the sum of all of its steps.

• True

• False

A parallel solution takes as long as its sequential tasks plus the longest of its parallel tasks.

• True

• False

The _______ of a parallel solution is measured in the time it took to complete the task sequentially divided by the time it took to complete the task when done in parallel.

Parallel computing consists of a....

• parallel portion

• sequential portion

• both

• neither

Solutions that use sequential computing can scale more effectively than solutions that use parallel computing.

• True

• False, parallel computing can scale more effectively

• False, they can scale at the same level of effectiveness

_________ computing allows problems to be solved that could not be solved on a single computer because of either the processing time or storage needs involved.
