When did a person have a need for computing machines?

It appeared a long time ago, but man did not have the opportunity to build a computing machine – the technologies were not the same. The desire to carry out a large number of calculations, for which the speed of the human brain was insufficient, led to the appearance and development of the first calculators and computers. As the volume and complexity of computing grew, so did the need for faster and faster computers. Computing machines simplify and make life easier for people, and in many areas they are irreplaceable (for example, in scientific research).
