Illustrated CPUclock frequency of

The personal computer has become everyday life complicated, but knowing that, the based clock integer time or semi- integer it is something which is doubled, details of this being very special, perhaps the clock frequency of CPU you have not excessively understood other than the upper-class user.

Especially, as for up-to-date Centrino Duo FSB became 800MHz, but being able to understand the Dynamic Front Side Bus Frequency Switching function which is added because of this as for the one which is which extent it will be?
As for the upper-class kind of user which does the over clock with the desktop personal computer anyhow, as for the general user, that “the based clock by the fact that from 200MHz it makes 100MHz, CPU operates with 600MHz”, being explained, although FSB is 800MHz, as for 200MHz of the based clock if… and so on, there is no knowledge which becomes prerequisite from somewhere, also it has become many not to be able to understand.

Then, up-to-date Centrino Duo in order on the basis of to be able to understand the operation of the clock frequency of CPU, even with the personal computer beginner, explaining, like.

Clock frequency

It is tempo in order to take the timing of processing in each circuit inside the computer.
the analogy to human, pulse is like, signals are exchanged for this tempo, to allow faster flow of blood the higher the pulse, the higher the clock frequency, signals are also fast flowing.
the more you faster clock frequency, the computer is faster, not stand as the body becomes too high pulse, when the clock frequency is also higher than the provisionsCPUbehavior is impossible.

the unit is hertz(Hz)in, 1if hertz1second1means the frequency of the times.
if your computer, mhz(MHz)or gigahertz(GHz)is common
mhz10of6power is, 1,000,000Hz
ghz10of9power is, 1,000,000,000Hz

that is1GHzif the, 1second10but that one hundred million times.

recently, multi-core software for the operation at the same time have more than oneCPUwill speed up the operation speed of more, 1there are also applications that do not move the only process. in that case, to stop the core of one, the behavior of the core of the other1by increasing stage, technology to increase the frequency.
