Manish and Harish are employed in a computer hardware store as movers. One day both of them are asked to move some computers. Harish being energetic that day doesn't feel the computer to be heavy at all.At the same time he sees that Manish is struggling very hard to lift his computer. At this says Harish, "What Manish, My computer has 500 MB Hard disk and yours has just 250! Even then you can't lift it why? Manish thinks for a while and replies, "That's right, but my Hard Disk is full and yours is empty."
