What are example of multiprocessor system?
Multiprocessor systems have gained popularity over the years as they allow the user to do more than they could with a single processor system. Xbox 360, CELL, and Sequent are examples of multiprocessor systems.
What are different types multiprocessor system?
A multiprocessor system is any device with multiple processors(processing cores). These days, you can buy up to an 8 core PC, (apple's new mac pro) http://blogs.zdnet.com/Apple/?p=485 But most people with gaming PC's have at least a duo-core processor. They used to be very expensive, but now they are affordable. But you'll usually hear that term associated with PC or computing devices. It makes everything faster, especially multitasking.
Explain why spinlocks are not appropriate for single-processor systems yet are often used in multiprocessor systems?
A spinlock is basically a loop that constantly checks a condition until it is true. Think of a bunch of kids in the back of a car saying "Are we there yet...are we there yet...are we there yet...". This is a poor implementation for almost any setup, since the lock is wasting processor time that could be doing something more efficient than constantly checking a condition over and over. Also, while the spinlock is running on the processor, the system will be completely unresponsive.
What are the disadvantages of multiprocessor system?
If we divide functions among several processors, then if one processor fails then it will not affect the system or we can say it will not halt the system, but it will affect on the work speed. Suppose I have five processors and one of them fails due to some reasons then each of the remaining four processors will share the work of failed processor. So it means that system will not fail but definitely failed processor will affect on its speed. Another significant disadvantage of a multiprocessor system over one using a single single-core processor is a considerably more complex hardware and software design, as algorithms and tasks need distributing among the cores and processors to maximize the benefit of parallel processing, while an effort to synchronize access to shared resources such as main memory and most I/O devices is required.
How can I tell which laptop models are the fastest?
A computer's processor determines the speed. The bigger the processor, the faster the computer. If you're interested in speed over the long-haul, buy the best processor your budget allows.
What is the advantage to choosing a Mac over a PC?
The Mac processor is much faster than that of the PC due to high memory capacity and it can be used to download things faster
What is the advantages of multicore processor over single core processor?
Hyperthreading is cheaper, and will produce less heat. Overall though, dual-cores are better.

What is an I-64 processor architecture and what are it's advantages over Pentium processor?
It is a processor that works with 64 bit values instead of 32 bit values. The advantages are that it is much faster for operations on large 64 bit values for which a 32 bit processor would need multiple operations. This means that a 64 bit processor with the same clock speed can do more work in the same time.
Is there any speed difference between a 2.26 ghz mac and 2.53 ghz mac?
The speed of a 2.53GHz processor is a little over a quarter of a gigahertz faster than a 2.26GHz processor. The difference would not be noticeable to an average user doing everyday tasks on the computers.
Is a dual processor CPU better?
Whether or not you get any benefit from a dual core processor over a single core processor depends on what operating system and what programs you are running. Newer operating systems (Windows 7, Mac OSX) do use multicore processors. Also, using multiple programs on a computer will better utilize a multicore processor. In short, yes it can make a difference for today's average user.
