Hvad  er vigtigt for computerens ydelse, og hvordan den kan måles 

Først og fremmest:

MURPHY’S LAWS OF COMPUTING 

1. For every action, there is an equal and opposite malfunction.
2. To err is human… to blame your computer for your mistakes is even more human; in fact it is downright natural.
3. He who laughs last probably made a back-up.
4. If at first you don’t succeed, blame your computer.
5. A complex system that does not work is invariably found to have evolved from a simpler system that worked just fine.
6. The number one cause of computer problems is computer solutions.
7. A computer program will always do what you tell it to do, but rarely what you want it to do.
8. When computing, whatever happens, behave as though you meant it to happen.
9. When you get to the point where you really understand your computer, it’s probably obsolete.
10. The first place to look for information is in the section of the manual where you least expect to find it.
11. When the going gets tough, upgrade.
12. When you need to send an email quick, that’s when the modem won’t connect!

Men her er der  4 simple faktorer der gør sig gældende for en computers ydelses evne:

1)  CPU (processor) Ghz

I en processor er Ghz den tidsmæssige frekvens. En god processor skal helst have en Ghz på over 2.4 (mindst).

2)Processorens kerner

1-2-3-eller 4 kerner. Flere kerner i din processor (CPU) bestemmer hvor god den er til at udføre flere opgaver på samme tid.

3)Harddisken

Rpm beskriver den hastighed skiven roterer med. En fin rpm er 7200. En hurtig roterings hastighed giver en hurtigere læsning.

4)God CPU køler

Det er ikke godt hvis computeren har en dårlig CPU køler. Ligesom din hjerne ikke funger hvis det er over 40 grader, kan din computer blive overophedet og til sidst gå i stykker. Mange virksomheder der laver computere tager deres nedkølings teknik meget alvorligt. Det gør en stor forskel for om en computer er meget værd eller går i stykker hurtigt.
