As the image shows number of processors are 4.
But intel i5-4210U has only 2 cores as shown below. (Intel's own specs.)
So, if i5-4210U has only 2 cores than what is "4" indicating in the 1st pic?

Best Answer
Your CPU has only 2 cores, but supports 4 concurrent threads.
This is achieved by Intel's Hyper-Threading technology that allows to run two separate threads in parallel at the same time on one single core.
So 2 cores x 2 threads per core means 4 threads per CPU.
