Dual Core Processor




A dual core processor is a CPU with two separate cores on the same die, each with its own cache. It's the equivalent of getting two microprocessors in one.

In a dual core processor, each core handles incoming data strings simultaneously to improve efficiency. We know two hands are better than one. Now when one is executing the other can be accessing the system bus or executing its own code.
Example: Intel Core Duo

Why Dual Core?
A dual-core processor has two cores on the same die.

This means that signals between different CPUs travel shorter distances, and therefore those signals degrade less. These higher-quality signals allow more data to be sent in a given time period, since individual signals can be shorter and do not need to be repeated as often.
A dual-core processor uses slightly less power than two coupled single-core processors, principally because of the decreased power required to drive signals external to the chip

A dual core processor combines two processors and their caches and cache controllers onto a single integrated circuit (silicon chip).

Now its clear. Dual core is nothing but two hands working together instead of one.

Dual core is just another name of Core2 Duo.
I wanna know, is i3 better than core2duo?

Realm Head said...

Certainly, i3 is better than core2duo in terms of performance. And now we have i5 an i7, which are even better.

I wanna ask how to change the status bar message of my html page. I do not wan my user to see the the link on the status bar. Just for Fun!
Is there any way 4 dis?

Thanks.
I implemented it on my webpage. Looks cool. Will try my hand with other tricks as well. Thanks a lot.
