Computers are categorized by a wide variety of factors, including size, calculation speed, processor power, processor number, price and application. Some computer categories emphasize a leading capability in one particular aspect while others require a computer to have minimum capabilities in a wide range of characteristics. Many computers can work in several categories, but are optimized for a particular use. The nine categories listed demonstrate the wide range of applications found for computer technology.
Supercomputers
These are the most expensive and the fastest computers. They usually have many of the most powerful processors available, and evaluate complex models. They are categorized by the speed at which they can perform calculations, and are used for large, chaotic, dynamic systems like weather patterns or the turbulent flow of air around an airplane. Cray and IBM make supercomputers.
Mainframes
Mainframes are large, powerful computers characterized by their ability to handle thousands of incoming connections. Typically used by large institutions and companies to allow staff and customers to access data and perform operations, they usually don't have to handle complex tasks, but must handle many simple tasks simultaneously. IBM and Amdahl are mainframe suppliers.
Servers
While mainframes can be located remotely, servers in a business environment are usually on the local area network, and handle fewer connections. Servers deal with email, webpages and Internet connections and store company data. A company may have many servers, each dedicated to specific tasks. IBM, Hewlett-Packard and Dell are major suppliers of servers.
