The object of this article is part of the logic of computerization of mathematical calculations. The countless mathematical calculations prove to be tedious and complicated, even impossible to perform manually and the considerable time required to process them. This is particularly with regard to the calculations of the probability of the life annuity to allow the National Social Security Fund (CNSS) in acronym of the province of Haut-Katanga to determine the result in a few seconds, to ward off errors and remove fatigue. A life annuity is a sum of money, called arrears, that a person (the annuitant or the insurer) undertakes to pay periodically to another person (the insured or the annuitant) until the death of that person. this.

Since life insurance operations are linked to the length of human life, their implementation absolutely requires the calculation of the probabilities of death or survival from mortality statistics.
The object of this present work falls under the optics of the comparison of two operating systems.Doing a comparative study between the Windows and Linux system will make it possible to identify the strengths and weaknesses of each system in order to choose which is the most efficient compared to the other.An operating system can be defined as a system program that controls the execution of application programs. It is responsible for loading and running application programs. He must ensure the availability of the required hardware and software configurations before executing the application program.It is responsible for loading and running application programs.
