Here's the solution to question 2. 2. The most suitable category of computer likely to be used for solving complex application such as Global Weather Forecasting. A. Super Computers: These are high-performance computers designed to perform complex calculations at extremely high speeds. They are essential for tasks requiring massive computational power, such as climate modeling, weather forecasting, and scientific research. B. Mainframe computers: These are large computers primarily used by large organizations for critical applications, bulk data processing, and transaction processing. While powerful, they are not typically optimized for the kind of scientific simulations that supercomputers handle. C. Mini computers: These are smaller, less powerful, and less expensive than mainframes, often used for specific tasks in businesses or scientific labs. D. Micro computers: This category includes personal computers like desktops, laptops, and tablets, which are not powerful enough for global weather forecasting. Global weather forecasting involves intricate simulations and processing vast amounts of data, requiring immense computational capabilities. Supercomputers are specifically designed for such demanding tasks. The correct option is A. The most suitable category of computer for global weather forecasting is $\boxed{\text{A. Super Computers}}$.
