Difference between uniprocessor and multiprocessor computer system?

Answer 1

Single-processor system has only one actual processor, while Multiprocessor system has more than one, both types of systems can have more than one core per processor.

Multiple processors per system have long been used in systems that need a lot of processing power, like high traffic servers and when lots of computational power is needed. However these systems have been expensive and not needed by normal home or office users.

In recent years it's become typical that one processor has 2, 3, 4 or even 8 cores. These multicore processors behave the same way as if you had multiple processors.

One core can only do one task at a time. Multitasking is done by sharing the time of the processor between processes (program), one process runs for a short time, then another, then another or maybe the first one again. The switching is done so fast that the user wont know the difference. Multiple cores can run multiple processes at once for real.

It depends on your software how well you computer can use the advantage of having multiple processors/cores, dividing the task to different processes.

Answer 2

Single is one and multi is more than one...(simple Answer)

single processor vs Multiprocessor where single can only computer 1x its speed multi can computer up to the max number of processors it has but sometimes will not use those other cores until heavy process strain is placed on the first core

Answer 3

Multi core processors have two cores that can handle executing processes on one chip. Typicaly each core has its own L1 cache and the they will share L2 cahce. These chips are found in PC and Laptops now a days. Multi processors are multiple chips that are pluged into the mother board, each chip with have its own cache and none of it is shared. These are usually used in server applications or for developers. They are not for gaming and most home users (there are always exceptions).

Answer 4

A multiprocessor computer uses multiple processors. For central processing units, these are typically the same processors (i.e. four Pentium processors, etc). When using multiple CPUs, these can execute different tasks simultaneously, while sharing system resources such as RAM or access to hard drives.

Multicore computers don't exist, but multicore processors do. Any processor used within a computer can have one or more cores, where each core implements the core components of the processor. Multiple cores can execute different tasks simultaneously, while sharing resources such as access to any external components such as RAM or I/O.

Multicore processors aim at the same goal than multiprocessor computers at a lower cost (multiple cores in one chip is much cheaper than multiple chips with one core each), but the sharing of resources between the cores begins at a different level compared to a multiprocessor system.

Powerful modern computers combine both technologies, using multiple multicore processors.

Answer 5

a multiprocessor has multiple cpus or execution units under integrated control while a uniprocessor only has a single cpu and sequentially works on one task at time.

Answer 6

uniprocessor take sequential operation .mp take parallel data

Answer 7

It's not a trick question. A uniprocessor computer has one processor. A multiprocessor computer has more than one processor.

Answer 8

multiprocessors have a lack of scalability and multicomputers provide scalability and fault tolerance

Answer 9

A multiprocessor system has more than one CPU unit. A uniprocessor system has only one CPU.
