Is one megahertz really made up of one million hertz?

How do you quantify something like that?

 

[LEUVEN]

It just means it hurtz quite a lot.

 

[alex24]

I don't understand the question.

How do you quantify something like that?

In megahertz.

Welcome to 2010 we now have ghz

Imagine turning the light in your room on and off a million times in a single second...

For a cpu clock its a million cycles per second for a voltage to change from low to high and back again.

 

[Big.Wayne]

Sorry lol!

ummmm, how is it known that a million hertz make up a megahurtz? . . . i.e how do you measure it?

What academic realm deals with this kinda thing?

 

[blaineoliver]

1x10^6 times a second.

silly scope?

on a related note a fell down the stairs last night and it.....

It's not that humans discovered that a megahurtz happens to be a million hurtz. Mega is part of the S.I scale, including kilo, giga, pica, pico, e.t.c. We 'decided' that mega would be one million, and it is easily observed on an Oscilliscope.

Cool, hope you good at maths!

using your example then . . . . how many times would the light get switched on & off in one second on an Intel® Core™ i7 processor clocked to 4.0GHz . . . . and would Hyper-Threading affect this?

you been on the drink wayne?

the prefix mega- by definition means one million. Frequencies are measured with different apparatus depending on the phenomenon or type of technology we're talking about. I imagine with something like a CPU, a computer would measure it by calculating the time taken for certain known operations to complete to a high degree of accuracy. Sounds plausible enough.

Lol no sorry just trying to get my head around the numbers . . . not my strong-point so just putting it out here!

Start from 1Hz, its just a cyclical event an oscillation that repeats once per second. The frequency is the inverse of the time interval. All the major Engineering and Physics disciplines deal with frequencies. Measurement depends on the type of signal. For a cpu clock its a square wave, use an oscilloscope.

Like the above poster said, it's a made-up thing. One hertz just means one cycle (of anything) per second. So a megahertz is a million cycles. Hertz is a unit of frequency, like MPH is a unit of speed; frequency is just how often a repetitive thing happens in one part of time, in this case seconds.

you really bored by any chance

Hola!

You nOObed me out straight away . . . . oscillation

The frequency is the inverse of the time interval

Ok I'll get my coat!

All the major Engineering and Physics disciplines deal with frequencies

Thanks for that . . . I actually understood that sentence!

oscillation & oscilloscope? . . . . square wave!

Ok! . . . . obviously not a subject I'm gonna be very good in, thanks for the effort!
