Can somebody Help me out in this regard? what are the main Difference on Cores and Clock Speed of a Processor?

Clock speed is the speed of per core. ;)  i dont think theres more to add here but here you go: http://en.wikipedia.org/wiki/Clock_rate

Quad core = 4 cores
Quad translated = 4
Speed per core 3 ghz = total for quad core 16Ghz

if only it was that simply. the "speed" is actually how much "data" it can run through every cycle.
To understand a CPU down to the details can be very difficult, as many things becomes a factor.

Cores = Number of physical cores on a processor die.
Clock speed = Number of times the processor can switch on and off to process stuff (billions of times these days (G=billion, hz=x per sec).

also 3x4 = 12

but no, to get to this, you'd need a perfectly 4 threaded workload such that each core gets the proper amount of work to do. real world this never happens. so in fact you usually get 1-2 cores working all the time and the others kicking in when there's stuff to do.

As everything have been said and done, then REMEMBER that cores and clock speeds doesn't always reflect the performance of a CPU as architecture plays a big role nowadays. For example present Intel CPUs run much faster than AMD CPUs in most applications even though the Intel CPUs often have less cores and lower clock speeds.

Ok here is the easiest way i can think about putting it. Think of it like this: lets take a quad core CPU, each core would be its own CPU. each CPU is capable of doing different tasks. A quad core CPU is basically 4 single core cpu's put together.

clock speed is the MHz rate that the CPU will operate in the system. every piece of the system will have a Clock rate that it operates at.

each core will have a clock speed that it operates at. all cores should hit the same max clock speed.

the biggest difference between the clock speed and cores are the Cores are part of the CPU. the clock speed it the frequency that the CPU runs at.
