What does 'frequency' tight contained by admiration to computer processors?
Answer:
it funds the rate at which the processor can execute primitive operations. For example a 1 GHz processor can convey out 1 billion primitive operations per second.
Frequency is a standard of how many bites of background can be processed in a given time. 1Mb/sec would be 1 mega(million) bits of notes per second. The bigger the number the faster the proc. Faster and bigger are better! (not in physical size, demonstrably.)
Simply put, a computer processor has thousands of little "switches" set contained by circuits. A small current is sent around the circuits, going through the switches and depending on the combination of "on" and "off" positions of different switches, different computations can be done by the processor.
The frequency (often referred to as the speed) of the processor refers to how many cycles of the circuits surrounded by the processor are completed every second, for instance 1MHz implies that 1,000,000 cycles are completed per second and 1GHz would suggest 1,000,000,000 cycles.
It refers to the clock speed of a processor, contained by general the faster the clock speed the better the processor. This is not a spotless way to peacemaker the speed though due to different ways to calculate this, intel are movind away from using clock speed to rate processors.
A 2MHz AMD processor works out faster than a 2MHz intel (could be other style round). Processors will probably rated by FLOPs within future which is a benchmark of the number of operations per secon it can do.
Computer speed can also be artificial by the other components in it such as memory, bus speed and complex drive etc.
