What's the difference between "Dual Core Technology" and "Intel Core 2 Duo"?

This much answer:

1. Dual Core is a technology where two processor cores are fabricated on a single die so as to increase real-time processing performance.while Intel Pentium D andIntel Core2 Duo are Intel Processor Product that use this technology.
2. "Dual core technology" was to tell that the Pentium D was a dual core chip. The Core 2 Duo also has dual core technology, however the Core 2 Duo is much better than the Pentium D.
3. The Pentium D with dual core technology was Intel's first dual core processor, based on the Pentium 4, and was released in 2005 to get Intel back into competition with AMD, which at the time had the best performing dual core technology with the Athlon 64 X2. After that, Intel quickly released the Core Duo architecture, followed by the Core 2 Duo, both of which were significant updates of the Pentium M architecture used in laptops, and adopted by Intel as the basis of its "Core" platform for desktops and notebooks.
