Concept:Weather forecasting needs a computer with extremely high speed and large processing power.
Explanation:A supercomputer is the fastest and most powerful category of computer.
It can process huge volumes of data and perform billions of calculations per second.
Weather forecasting involves analysing atmospheric data, climate models, and complex mathematical simulations.
These tasks require massive processing power that ordinary general-purpose computers and microcomputers cannot handle.
Special-purpose computers are built for limited tasks, not for the broad, large-scale calculations used in weather prediction.
Therefore, the category of computers used for weather forecasting is supercomputers.
They are also used for scientific research, nuclear simulations, and space exploration.
Answer:The correct answer is C. Super computers.
