What are computers?
Computers are electronic devices to store and analyse data according to what instructions they are given. We use computers all the time, at home, school, work, everywhere. Before the computers were available to everyone, it was really expensive because not a lot of computers were made back then and because the software and the programming were complicated for people who haven't used them before. Also, computers back then were humongous and slow compared to now acquiring teams of people to operate those computers. However, as companies were launching more and more new products, it caught people's attention since it was easier and convenient to use and also because it was more available. The companies started to fight over the computers and released more products that were appealing to consumers which became more lighter and bigger opposite to the early computers launched in the 1960's.
