Difference b/w Dual core and core 2 duo

[otomanb]

I have always confusion b/w these two processor what's the major difference b/w these technology wise
Thanks

Duo is just Intel's processor name for 2 cores. They have core 2 extreme, or core 2 quad with four cpus.

Duo is processor for intel and there are four other CPU...

Dual Core is intels older line of dual core processors. Core2Duo is their newer line which will be replaced by the i5 I believe.

As BlackVenom stated, both utilize two physical processors on one die. The only difference is that the Core 2 Duos use two newer generation processors.

Dual core simply means 2 cores, while core2duo is a new line of processors.

We have Pentium dual core but Pentium core2duo doesn't exist cause Pentium is a different processor class and core2duo is a different one. Similarly we also have core2quad which is basically 2 core2duo's in one CPU die making a total of 4 cores. On the other hand i7 also has 4 cores but it's a different family.

A different family usually means major architecture differences.
