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!

Ответ:

1. Scientists use supercomputers to do experiments that might be difficult or dangerous in the real world. (Ученые используют суперкомпьютеры для проведения экспериментов, которые могут быть сложными или опасными в реальном мире.)

2. A supercomputer can do more than one quadrillion calculations per second. (Суперкомпьютер может выполнять более одного квадриллиона вычислений в секунду.)

3. A supercomputer is powerful because it has many CPUs (Central Processing Units). (Суперкомпьютер является мощным, потому что у него много центральных процессоров (CPU).)

4. Virtual physical worlds are useful to scientists because they help them with research. (Виртуальные физические миры полезны для ученых, потому что они помогают им в исследованиях.)

5. Supercomputers can help aeroplane pilots by showing how to save fuel by flying with the wind. (Суперкомпьютеры могут помочь пилотам самолетов, показывая, как сэкономить топливо, летая по ветру.)

6. The 'ultimate supercomputer' will be able to think and act just like a human brain. ("Совершенный суперкомпьютер" сможет думать и действовать так же, как человеческий мозг.)
