It may sound astonishing, but a small enterprise nowadays has bigger computation capacity, than the NASA had at the time when Apollo 11 first landed on the Moon. In order to exploit this capacity, grid is needed. Users of desktop PCs do not use up all of their capacities, as a matter of fact, they only use a few percentage of the CPU, while the computers inevitably amortize at the same time. Picture a company with hundreds of employees, who are working together, sometimes going to meetings, having coffee-breaks, completing tasks that isn't processor-intensive, thus this company has a vast amount of unused capacity. That's why purchasing a very expensive supercomputer would be unnecessary, because the company already has huge stockpile in this area, which can be united and applied with the help of grid.

This capacity can be carried out not only within an internal network, but also, under certain circumstances, among the computers connected to the internet. Thus the main point of the grid is to combine the unutilized power of desktop PCs and supercomputers into a giant virtual computer. Although the conception of the internet is also based on the file and information share among computers, the grid towers above this theory. Thousands of researchers are working on the materialization of the grid, for the potentials are not only enormous, but limitless. Vint Cerf, who laid out ARPANET, the predecessor of internet, is reckoned to be the father of the internet. In an interview, he claimed the grid to be the internet of the future. Indeed, grid is "The Technology" of the future, because with this new generation of computation service, the key to most social, scientific and economic questions will be available at our fingertips, costing way less than the old supercomputers.
