Describe the different classes of computers

The five general classes of computers are supercomputer, mainframe, server, workstation, and personal computer.• A supercomputer is the most expensive and most powerful kind of computer. It is used primarily to assist in solving massive scientific problems.• A mainframe computer, while being very large, is used primarily as the main, central computing system for major corporations. Optimized for high availability, resource utilization, and security, mainframes are typically used for mission critical applications, such as transaction processing.• A server is any computer on a network that makes access to files, printing, communications, and other services available to users of the network. Servers are used to provide services to users within large organizations or to Web users. Servers are optimized for access by many concurrent users and therefore have more advanced microprocessors, more memory, a larger cache, and more disk storage than single-user computers.• Workstations, designed for medical, engineering, architectural, or animation and graphics design uses, are optimized for visualization and rendering of three-dimensional models, and typically have fast processors, large memory, and advanced video cards.• Personal computers (PCs) are used for personal computing and small business computing. In addition, portable computers—notebook computers, netbooks, tablets, and smartphones—have increasingly become part of an organization's information systems infrastructure
