Humans invented computers to basic calculations and to keep records. With the time and after implementing the first computer generation computers, engineers and businesses kept researching about computers to make them more user friendly and cost efficient. 

Computers were not fast as now in early days. They were slow, large in size, costed more than a house, needed so much knowledge to operate. With the time and as a result of researching and investments into the development of products, Computers became what we used today on daily basis.
