Supercomputers are the fastest type of computers available, performing at speeds, which are far above that of the normal, every-day computers. First introduced in the 1960s, modern supercomputers have continued to improve, operating at speeds of about tens of teraflops, translated as trillions of operations per second and beyond, reaching the petaflop level (quadrillion mathematical computations per second). Recently, scientists at Department of Energy's Lawrence Livermore National Laboratory in California, US, announced the installation of Sequoia, a new supercomputer which is estimated to be the most powerful supercomputer in the world.
