Dual core vs single core

[Rohitchampion]

What is exact difference between 1GHz dual core processor and 1GHz single core processor? And what is difference between 2GHz single core and 1GHz dual core processor?

Dual-core has two cores and single-core has one core.

I don't know how technical answer you want.. did you try google. There are tons of articles that explain the difference: https://lmgtfy.com/?q=dual+core+vs+single+core

Obviously I tried google before posting here.. But confused about whether 1GHz dual core is same as 2GHz single core??

No...the processors are paralleled I believe (as opposed to cascading).

They both operate at 1GHz, but each one shares the processing load. The theory is that two paralleled 1GHz processors process a given amount of data within the same time frame as it would take a single 2GHz processor to process the same amount of data. But they're both still running at 1GHz.

The first article google finds (Yahoo answers) says that a 1Ghz dual core equals roughly 1.6Ghz single core. This debends on many things.. the operating system, how well the software is written, what the software does etc.
