Just what I needed. I have questions sometime and I think to myself, hmmm nah that is not a "techie" question, but I just want to know. So suffice it say, I like this a lot.

Question

I have a quad core processor.
Understand that quad = 4. I am picturing this as 4 sections
So if I open 1 program, does it go to first section
next program goes to second section or does it use the same section as 1st program

If I have 4 programs open, are all 4 sections being used?

Is there a way to see the processors in action, kinda the same way you can see space used on your hard drive.

So by now you are probably ROFL, :lol2: :lol2: when you get off the floor, all responses are appreciated. This is now my favorite section of the site.

Hey Ebony - Nobody should ROFL. Your question is actually a very good one and your assessment of what happens is pretty close, if somewhat simplified. This sort of technology is not exactly my forte but here is my understanding in basic terms:

Quad core includes 4 independent processors. What you are describing is known as multitasking, and yes, the way you described it is pretty accurate.
 

If I have 4 programs open, are all 4 sections being used?

 

Essentially, yes.

There are other considerations however, particularly regarding single programs and running multiple tasks - known as threads.

Take a game for example, where you might have separate tasks such as sound, AI and graphics all running concurrently. In a single core system these tasks are all trying to share the same processor, but in a multi-core system they can be spread over multiple processors. HOWEVER, this is totally reliant on how the software is written in the first place. The software must be coded to tell the system to utilize multiple cores - this is known as multi-threading. If the software does not include these instructions then the workload will generally not be shared regardless of how many cores.

As I said Ebony, this is an oversimplification of what is a fairly complex process, but it should adequately explain the basics.

As for the second part of your question: No, as far as I am aware there is no way to see exactly what the processors are actually doing, and I believe it would be happening so quickly it would be nigh on impossible to see it anyway. You can view a graphical representation for each core in Task Manager under the Performance tab.

You are definitely on the right track. Hope I've helped clarify a little. :)
Cheers...Jim

If you are on Windoze 7, you can install the "CPU Usage" gadget which gives a visual indicator of how much RAM and how much of each core is being used.

Caduser - Does your desktop CPU Meter show separate cores? Mine doesn't, just one usage meter for the lot.

Uninstall question
I am running W7 64 logged on as administrator, or so I thought.
However sometime I when I attempt to do things like delete a file, install sw, I get "I do not have the proper "permission".
So I take ownership. Still get the same message.

So my question is what settings do I check or can I change so I do not get this message?
