For these studies scientist use IBM’s powerful supercomputer “Roadrunner” at National Laboratory
Earthquake studies-Supercomputers are used to study the Earthquakes phenomenon. Besides that
supercomputers are used for natural resources exploration, like natural gas, petroleum, coal, etc.
Weather Forecasting-Supercomputers are used for weather forecasting, and to study the nature and
extent of Hurricanes, Rainfalls, windstorms, etc.
Nuclear weapons testing-Supercomputers are used to run weapon simulation that can test the
Range, accuracy & impact of Nuclear weapons.

2. Mainframe computer:-Although Mainframes are not as powerful as supercomputers, but
certainly they are quite expensive nonetheless, and many large firms & government organizations
uses Mainframes to run their business operations. The Mainframe computers can be accommodated
in large air-conditioned rooms because of its size. Super-computers are the fastest computers with
large data storage capacity, Mainframes can also process & store large amount of data. Banks
educational institutions & insurance companies use mainframe computers to store data about their
customers, students & insurance policy holders.

3. Minicomputers:-Minicomputers are used by small businesses & firms. Minicomputers are also
called as “Midrange Computers”. These are small machines and can be accommodated on a disk
with not as processing and data storage capabilities as super-computers & Mainframes. These
computers are not designed for a single user. Individual departments of a large company or
organizations use Mini-computers for specific purposes. For example, a production department can
use Mini-computers for monitoring certain production process.
