Computers are well known to represent a completely new branch of science, the first of them having appeared less than 60 years ago. Although still new, these machines are already bringing about a real revolution in science, technology, statistics and automatic control.
The reason for this is the fact that a mathematical formula can be found for almost all scientific and technical problems. They can be solved without a computer but it would require millions of arithmetical operations.
Electronic computer with a high speed can carry out several thousand arithmetical operations in one second. A calculation which would have taken several years of intense human work in the past is now done in a few minutes or hours. A number of various complicated problems have already been solved with the help of computers.
The principle of this wonderful machine lies in counting electric impulses. Numbers are represented as a sequence of such impulses and a radio-technical scheme counts them carrying out addition, subtraction, multiplication and division of all higher mathematical calculations being reduced to these four operations.
Electronic machines work according to a program prepared in advance which determines the sequence of operations. They have a very efficient electronic memory which stores the initial date, the intermediate numbers and final results as well as working commands given to the machine.
