Core 2 duo is dual core. And before that was core duo which was dual core too...
the difference is core 2 duo gives more cooler temperature and supports more features than dual core processors
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.
dual core processors allow for twice as much data processing thus making computer much faster and stable.
A single core processor is just that... one processing core. A dual core processor is actually two processing cores on one chip. It is like having two processors in your system, but it is faster than two individual 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.

Intel E processors are dual core, whereas Q processors are the newer quad core versions. For a definition of multi-core systems see: http://en.wikipedia.org/wiki/Dual_core
The Intel Atom is available in both single core and dual-core varieties.The following Atom processors are single-core processors:230D410N270N280N450N470Z500Z510Z515Z520Z530Z540Z550The following Atom processors are dual-core processors:330D510

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.
