I no its giga hertz or something like that but what do they actually do on the computer...this has always bugged me and is there a way to upgrade it?

Erm... http://en.wikipedia.org/wiki/Ghz - it's how fast your processor is.

Gigahertz is the frequency of something.

In computer terms it's how many operations a computer can perform within one second.

1 gigahertz = 1 billion processes. 2 gigahertz = 2 billion processes and so on... it gets bigger and goes into terahertz which is equivalent to a trillion operations.

You can overclock your current processor to make it pump out more hertz than it already does...but this might crash it. If you're not feeling risky, you could try buying an entirely new processor to upgrade speed.

That Wonderful Wiki Hertz

From Wikipedia, the free encyclopedia

(Redirected from Gigahertz) Jump to: navigation, search For the radio pioneer, see Heinrich Rudolf Hertz. For other uses, see Hertz (disambiguation). The hertz (symbol: Hz) is the SI unit of frequency. In English, hertz is used as both singular and plural. Contents

[hide]

// [edit] Definition

One hertz is defined as the reciprocal second. 1 Hz = 1 s−1 [edit] SI multiples

Multiple Name Symbol Multiple Name Symbol 100 hertz Hz 101 decahertz daHz 10–1 decihertz dHz 102 hectohertz hHz 10–2 centihertz cHz 103 kilohertz kHz 10–3 millihertz mHz 106 megahertz MHz 10–6 microhertz µHz 109 gigahertz GHz 10–9 nanohertz nHz 1012 terahertz THz 10–12 picohertz pHz 1015 petahertz PHz 10–15 femtohertz fHz 1018 exahertz EHz 10–18 attohertz aHz 1021 zettahertz ZHz 10–21 zeptohertz zHz 1024 yottahertz YHz 10–24 yoctohertz yHz [edit] Explanation

One hertz simply means "one per second" (1 / s); 100 Hz means "one hundred per second", and so on. The unit may be applied to any periodic event – for example, a clock might be said to tick at 1 Hz, or a human heart might be said to beat at 1.2 Hz. Frequency of aperiodic events, such as radioactive decays, is expressed in becquerels. To avoid confusion, periodically varying angles are typically not expressed in hertz, but rather in an appropriate angular unit such as radians per second. A disc rotating at 1 revolution per minute (RPM) can thus be said to be rotating at 0.105 rad/s or 0.017 Hz, where the latter reflects the number of complete revolutions per second.

Its just the number of times your cpu does one clock cycle per second.

If you are picking up a new cpu dont look at GHz speed for exe: a AMD 2.2 GHz 3200+ is as fast or faster than a P4 at 3.2 Ghz.

actually i have an amd athlon 3000+ which is neck to neck with my friends Pentium d processor so yes get an amd not an intel if your thinking on buying a new procesor

GHz doesn't necessairly mean speed, however. Think of it like this...

Processors are like highways. Pentium and AMD processors have high speed limits. PowerPC processors, used on all the pre-Intel Core Apple computers (PowerBook, iBook, PowerPC G5) have more lanes.

I don't believe anyone mentioned the frequency equaling how fast a processor will ultimatly run.

AMD don't have excessively high clock frequencies either.

Do my posts have to be in reply to something stated by someone before me?

No, you're done.

I'm trying to help the kid understand this in an easier way, if you can't appreciate that, then leave me alone.
