Processor speed is not as important as it was.Anything above 1.5 Gig is plenty fast for most needs.RAM is more important.Get 1 Gig,more is usually a waste.Don't expect to suft the net on dialup.You need DSL.
Computers nowadays come at around 3 GHz. It has been difficult to make this so-called "clock speed" faster and faster; instead, computers nowadays have larger amount of processors or cores.When buying a computer, you should consider your needs. If all you need to do is edit some documents in Word and Excel, and browse the internet, you probably WON'T need an extremely fast computer; any new computer will be more than fast enough.
For other tasks, you might need a faster computer, or more hard disk space, than what is available on the cheapest computers.
The computer speed depends on the processing speed in GHz, and on the number of processors or cores. But if you run many programs at the same time, or large programs, the amount of RAM can make a HUGE difference as well.
Current computer processor speed is about 2ghz, but older models are still in use. Average computer processing speed has increased dramatically in recent years.
processing speed of the computer will be increased when the data bus is wider
this means your computer have a processor with 513 MHz processing speed.
How do buses contribute to an computer
You can tell your computer's make and processing speed by checking out System Properties in Windows. On Windows 7 & Vista, just right click the Computer icon and select Properties.

Computer processing speed is measured in IPS (Instructions per second).
it is the central processing unit
A uniprocessor system is defined as a computer system that has a single central processing unit that is used to execute computer tasks.
Gigahertz is equal to 1,000 megahertz and is used in measuring speed of computer processing.
There are websites that offer software which you can download and install to test your computer processing speed. One such website is here: http://computer-speed-test.info/how-to-test-the-computer-processor-speed/.
