Mainframes
A mainframes is a large, expensive, powerful computer that can handle hundreds or thousands of connected users simultaneously. Mainframes store tremendous amounts of data, instructions and information. Most major corporations use mainframes for bunisess activities. With mainframes, large business are able to bill millions of customers, prepare payroll for thousands of employees, and manage thousands of items in inventory.
Supercomputers
A Supercomputers is the fastest, most powerfull computer and the most expensive. The fastest supercomputers are capable of processing more than 100 trillion instructions in a single second. With weights that exceed 100 tons, these computers can store more than 20,000 times the data and information of an average desktop computer. Applications requiring complex, sophisticated mathematical calculations use supercomputers. Large-scale simulations and applications in medicine, aerospace, automotive design, weather forecasting, nuclear energy research use a supercomputer.
