Abstract
Today, computers are used in every kind of human activity (from scientific research to the service sector). This article covers the topic of software reliability increasing in connection with the importance of maintaining reliable and fault-tolerant software operations in critically important fields of science and technology for humans. The paper describes such methods of software reliability improving and protecting it from the errors influence, such as the method of recovery blocks and N-version programming approach. The constructive principle is described, and a diagram of the method of recovery blocks is given. A comparison of the N-version programming method and the recovery blocks method was carried out, followed by a theoretical analysis of the advantages and disadvantages of the method of recovery blocks. The results of the experiment comparing these two approaches are presented.
