It was also very heavy. The ENIAC weighed more than 27,000 kilograms. It was very expensive. Plus, it was not easy to use. But it did a good job.

    Over the years, computers got smaller and smaller. They also got cheaper and cheaper. First, big businesses got computers. Then, small businesses bought them. Now, people have computers at school, work, and home. Our small computers are much faster than the ENIAC.
