Top 10 most powerful computers in the world

The world contains a limited number of supercomputers known as "SUPERCOMPUTERS", which carry out a range of sensitive and extremely accurate tasks. Supercomputers are used to run complex simulations that include a large number of variables. The importance of simulation stems from giving an opportunity to calculate results and providing an environment similar to reality for performing complex and highly sensitive experiments. Common uses of simulation models are in nuclear science, neurological research, epidemiological studies, viruses, including the Corona virus, as well as the study of economic and climate models. The list of the best computers includes 8 computers around the world, varying between three American devices, two from China, and one each from Japan, Germany and Italy.
