A supercomputer is a type of computer that is designed to perform computations at speeds orders of magnitude faster than a regular computer. Supercomputers are the most powerful type of computer system and are capable of performing billions of complex calculations per second. Supercomputers usually use advanced technologies such as massively parallel processing and vector processing to accomplish these tasks. Supercomputers are used for scientific and engineering applications such as nuclear weapon simulations, weather forecasting, deep learning, and artificial intelligence.
