Computer affects the peoples' life in a much bigger way then most of them might have thought. It has become a compulsory requirement in most professions to be able to use computer software. The first computer invented was the ENIAC in 1943 which was the same size of a large room, consuming as much power as several hundred modern PCs. Modern computers which are based on integrated circuits are small enough to fit into mobile devices. One of the most compacted computers out right now are table computers with the most popular being the IPad, but even that is 9.1inch and weighing about 700grams.
