Advantage and disadvantage of multiprocessor

Answer 1

A food processor is a multifunctional kitchen appliance that is designed to quickly and easily perform repetitive food preparation tasks like chopping, slicing, shredding, grinding, and pureeing. A food processor can be used to prepare almost any type of food. Importantly, a food processor can be a valuable time saving resource for any cook and eliminate stress that would otherwise be put on hands, wrists and forearms from repetitive cutting tasks.

the disadvantages are;

· They're usually really noisy

· They're hard to clean

· They might over cut, blend, chop, grate, need

· You don't have much control

· If you forget the lid to the tube it could go everywhere

· They are very dangerous to clean because of the sharp blades

Answer 2

Advantages: Multi-tasking capability is greatly increased, in other words if you have to run multiple programs at the same time multi-processors or multi-cores can be very useful. Another advantage of multi-processors is that more and more programs these days are multi-threaded. A multi-threaded application is a single program or application that can make use of more than one processor/core.

Neutral: Most normal users don't really make use of multiple cores or processors, especially in gaming it has been shown that even two cores does not have much more performance than one. There is almost no difference in performance between two and four cores for gaming. (a video card is a much better investment for high intensity gaming, see www.tomshardware.com as a reference)

Disadvantages: None really, other than cost and power.

Multi-processor vs. Multi-core? Having separate processors these days allows you to have even more cores, since each processor could have more than one core. Having more than one processor also will give rise to higher amounts of cache since a single processor with multi-cores only has one set of cache (L1, L2, and maybe L3 or others).

Answer 3

advantage

1.higher performance due to parallel processing.

2.if one CPU get failed other CPU are used to do that CPUs job.

disadvantage

1.complex OS is required.

2.large main memory requried.

3.very expensive.

Answer 4

Advantages of Multithreading
- Better responsiveness to the user - if there are operations which can take long time to be done, these operations can be put in a separate thread, and the application will preserve its responsiveness to the user input - Faster application - the work will be done by more objects

Disadvantages of Multithreading
- Creating overhead for the processor - each time the CPU finishes with a thread it should write in the memory the point it has reached, because next time when the processor starts that thread again it should know where it has finished and where to start from - The code become more complex - using thread into the code makes the code difficult read and debug - Sharing the resources among the threads can lead to deadlocks or other unexpected problems

Answer 5

a multiprocessor would have a disadvantage over a processor due to its ability to process more than one application at a time making the opportunity for errors to occur should the wrong process be selected but the advantage is its ability to do more than one task at one time which would save time and energy presuming the correct inputs are selected

Answer 6

Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor and/or the ability to allocate tasks between them.[1] There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined.

Advantage:

1.increase throughput

2.Economy of scale

3. Increased reliability

Disadvantage:

1) If one processor fails then it will affect in the speed

2) multiprocessor systems are expensive

Answer 7

*It's more complex.

*It requires context switching which slightly impacts performance.
