Hello All, My CPU is Pentium(R) Dual-Core CPU T4500 @ 2.30GHz × 2 and RAM is 3 GB. But Hadoop-2 in the following image says memory total 8GB and Vcores total 8. I would like to know that why this difference is?

Strange. Is this VM where the VM has been configured with 8GB memory and 8 cores although underlying hardware doesn't have such resources?

I'm not using any virtual machine. My system configuration can be seen in the pasted image
