Atlas Computer (Manchester) facts for kids
The Atlas Computer was a very important computer built in Manchester, England in 1962. It was one of the world's first supercomputers. Many people thought it was the most powerful computer in the world when it was first made. The Atlas computer helped change how computers worked forever.

What Was the Atlas Computer?
The Atlas was a huge and powerful machine. It was built by a team from the University of Manchester and a company called Ferranti International. This computer was special because it could do many things at once. It was much faster than other computers of its time.
How Powerful Was It?
The Atlas computer could do about half a million calculations every second. This was incredibly fast for the 1960s! To give you an idea, a typical computer back then might only do a few thousand calculations per second. The Atlas used new technology called transistors instead of older, slower vacuum tubes. This made it faster and more reliable.
Memory and Speed
The Atlas had a special way of managing its memory. It used something called virtual memory. This made the computer seem like it had more memory than it actually did. It was a very clever idea that is still used in computers today. This helped the Atlas run big programs and handle many tasks at the same time.
Why Was Atlas So Important?
The Atlas computer introduced many new ideas that are now standard in all modern computers. It was a pioneer in many ways.
Key Innovations
- Virtual Memory: This allowed the computer to use its hard drive like extra RAM. It meant programs could be bigger than the actual physical memory.
- Paging: This is how virtual memory works. The computer moves small blocks of data (pages) between fast memory and slower storage.
- Job Scheduling: The Atlas could run many different programs for different users at the same time. It had a special system to decide which program to run next. This made it very efficient.
- Operating System: The Atlas had an advanced operating system called the "Supervisor." This system managed all the computer's resources. It made sure everything ran smoothly.
Impact on Computing
The ideas from the Atlas computer influenced how future computers were designed. Things like virtual memory and advanced operating systems became common. Without the Atlas, modern computers might look very different. It showed what was possible with computer technology.
Where Was Atlas Used?
Only a few Atlas computers were ever built. They were very expensive and complex.
Main Locations
- University of Manchester: The first Atlas was installed here in 1962. It was used for scientific research and teaching.
- University of London: Another Atlas was installed at the University of London.
- Atlas Computer Laboratory: A third Atlas was built for the Atlas Computer Laboratory near Oxford. This one was used by many universities and research groups across the UK.
What Was It Used For?
These powerful machines were used for complex scientific calculations. Scientists used them for things like:
- Weather forecasting
- Nuclear physics research
- Engineering design
- Astronomy calculations
The Atlas helped scientists solve problems that were too big for other computers.
Legacy of Atlas
The Atlas computer was retired in the early 1970s. Even though it was only around for a short time, its impact was huge.
A Look Back
The Atlas project was a big step forward for computer science in Britain. Many of the people who worked on Atlas went on to do other important things in computing. The lessons learned from building and using Atlas helped shape the future of technology. It proved that powerful, multi-user computers were possible.
