No
Core 2 duo is dual core. And before that was core duo which was dual core too...
There is no difference between dual core and core 2 duo. Intel just name its recent family of dual core processors as "core 2 duo". Both (core 2 duo and dual core) works in same fashion.
the difference is core 2 duo gives more cooler temperature and supports more features than dual core processors
The quad core is better. As its 4 cores, the workload is spread efficiently between them so it runs smoother. But the quad core is more expensive.The Intel Core 2 Duo processor was designed to meet the demand for increased performance from PC users. It can run multiple, intense software applications simultaneously.
A generic "dual core" processor is any processor which has two separate processors on a single chip. This should not be confused with the Pentium Dual-Core, which was a brand of dual core processors which used the Pentium architecture on each core. The Core 2 Duo is also a specific processor from Intel. The Core 2 is a brand of microprocessors based on the Core architecture. The Core 2 Duo specifically refers to a dual core version of the Core 2 brand.
Seeing as Core 2 Duo sounds redundant (since 2 is the same as duo), I would say that Duel Core is more accurate, unless they are two different things. If they aren't the same, core 2 Duo could be an upgrade from duel core, but that just might be just me.
Pentium D is just the name Intel gave to that particular line of processors. Dual core technology means that the single chip has two processors on it. This makes it capable of executing two commands at the same time. Do not confuse Pentium D dual core with the newer Core 2 Duo. They are vastly different chips. The Core 2 Duo (and the Core 2 Quad) core chips are greatly improved over the Pentium D chips. Pentium D is just the name Intel gave to that particular line of processors.

The Pentium Dual Core has a smaller L2 cache than a Core 2 Duo. It essentially fills the same role as the older Celeron processors; a cost-reduced version of a more powerful chip.
Core2Duo is a dual-core processor (two processors), as the i5 is a quad-core processor (four processors). So the i5 is, significantly.
The difference is that Core Duo processors have to "engines" instead of one. With other words, Core Duo means 2 Intel processors in the same time working!
In computer processing, dual core processors are processors that feature two individual processing cores. 'Duo Core' is a brand of dual core processors associated with Intel Core 2 Duo processors. There is no difference, one is just a brand.
A processing core is a complete, independent processor. Each core has its own ALUs, fetch-execute cycles, pipelines, and cache, but shares some support circuitry with the rest of the processor. A dual-core processor simply means that there are two independent processors in a single package.
