does it mean the speed of both cores or of each core giving a total of 4Ghz? And when it says just T5500 or something like that how can you find out the speed?

Well alchemist that is a bit misleading, because it will not perform like a 2Ghz Pentium 4, it will perform much faster becaue of the Core 2 Duos better architecture.
Now he is right though, it means you have 2 2Ghz processors, which is not equivalent to 4Ghz, you can't just add. However you will see an increase in performance even when not using a multi-threaded process, because don't forget at anyone time between all the background programs running you have around 50 threads running.
As for how to determine speed, reference this page:http://en.wikipedia.org/wiki/List_of_Intel_Core_2_microprocessors

In the old days (which is really last year), processor speed (in GHz) would give a user a general idea of power, speed, reliability, etc. Nowadays... it's not the same. AMD has always kept up the pace by calling an AMD Athlon 1600... meaning it compares to an Intel 1.6 GHz... but the real processor speed is more like 1.2 GHz. Of course, if they marketed them like that, no one would buy AMD. So... it was like that for years... UNTIL! They started coming up with processors that have more cores, more throughputs, etc that allow for a slower processor speed but actually perform much faster.
So, what does 2 GHz mean? It means the processor runs at 2 GHz (which is pretty fast by the way for a Intel Core 2 duo)... but it DOES NOT mean that it compares to an Intel Pentium 4 2.0 GHz. Totally different chips... and the Core 2 Duo is MUCH faster.
Look on the I-net for a price comparison of popular processor speeds-- sadly you might only find the NEWEST technology, or some nerd's four year old review of a PIII.

It really means what it says: it's two 2.0 Ghz processors. In just about every piece of software ever written, it will perform like a 2.0 Ghz processor. In the less than 1% of software that is multi-threaded, it will perform roughly the same as a 3.5 Ghz single-core, because you only get a 75% increase from the second core, even in multi-threaded applications.
For almost every computer user (home user), the only reason, at least so far, to buy a dual-core processor is so they can multitask, with two applications that are cpu intensive.

When it says 2.0 ghz it means you have a 2.0 ghz machine..You have two processors but the stress is divided between the two depending on number of applications being used...most applications however will only use one of the processors so sometimes depeding on the actual work that needs to be performed a solo core in some cases is actually better then a dual core..

2 ghz is the speed of each core , giving you a total of 4ghz.

Each core is 2Ghz... so essentially 4Ghz.
