When the first computer was invented, the world did not realize its true value. Many failed to see how this machine was going to change the shape of the world in the future. But given that the earlier computers were not as advanced as the machines of today, the lack of interest showed by people is only justifiable. However, as time passed and improvements were introduced to computers, they became more and more important. Today, there is hardly any office that does not rely on computers. Even if computers aren’t involved in some tasks, they are essential for data storage.
