Supercomputers

Personal computers help us to communicate and organise our lives. They help us to work and also to have fun. But in science, the type of computer that we use every day isn't powerful enough. Scientists need more powerful computers to help them understand the world around us. They use these 'supercomputers' to do experiments that might be difficult or dangerous in the real world. Supercomputers are huge and are much faster than personal computers. Some of them can do more than one quadrillion (1,000,000,000,000,000) calculations in a second.

A supercomputer can work so quickly because it has many CPUs. The CPU, or Central Processing Unit is the brain of the computer. It can process information very fast and accurately. Scientists use this power to make virtual physical worlds that help them with research.

Every time you see the weather forecast on TV, you are seeing the work of very powerful supercomputers. Scientists use these computers to tell us if it's going to be sunny at the weekend, to show how aeroplanes can save fuel by flying with the wind, and also how the weather is going to change in the future.

As for the future, experts believe that one day computer scientists will build the ultimate supercomputer that can think and act just like human brains. Perhaps one day computers really will rule the world!
