This article needs additional citations for verification. (October 2013) This list of computer size categories attempts to list commonly used categories of computer by the physical size of the device and its chassis or case, in descending order of size. One generation's "supercomputer" is the next generation's "mainframe", and a "PDA" does not have the same set of functions as a "laptop", but the list still has value, as it provides a ranked categorization of devices. It also ranks some more obscure computer sizes. There are different sizes like-mini computers, microcomputer, mainframe computer and super computer.
The classes above are not rigid; there are "edge devices" in most of them. For instance, the "subnotebook" category can usually be distinguished from the "PDA" category because a subnotebook has a keyboard and a PDA has not; however, tablet PCs may be larger than subnotebooks (making it seemingly correct to classify them as laptops) and also lack a keyboard, while devices such as the Handspring Treo 600 have something that might charitably be called a keyboard, but are still definitely in the "smartphone" category. In the higher end of the spectrum, this informal and somewhat humorous rule might help:

Supercomputers – a powerful computer that can process large amounts of data and do a great amount of computation very quickly. Supercomputers are used for areas related to:
Supercomputers are useful for applications involving very large databases or that require a great amount of computation. Supercomputers are used for complex tasks, such as:
Mainframe computers– a high-performance computer used for large information processing jobs. Mainframe computers are primarily used in :
Mainframe computers are useful for tasks related to:
Minicomputers– a mid-range computer that is intermediate in size, power, speed, storage capacity, etc., between a mainframe and a microcomputer. Minicomputers are used by small organizations. “Minicomputer” is a term that is no longer used much. In recent years, minicomputers are often referred to as small or midsize servers (a is a central computer that provides information to other computers). Personal computers(PC) – a small computer designed for use by a single user at a time. A PC or microcomputer uses a single chip (microprocessor) for its central processing unit (CPU). “Microcomputer” is now primarily used to mean a PC, but it can refer to any kind of small computer, such as a desktop computer, laptop computer, tablet, smartphone, or wearable. Types of personal computers– a personal computer that is designed to stay at one location and fits on or under a desk. It typically has a monitor, keyboard, mouse, and a tower (system unit). Laptop computer (or notebook) – A portable personal computer that is small enough to rest on the user’s lap and can be powered by a battery. It includes a flip down screen and a keyboard with a touchpad. – A wireless touchscreen PC that is slightly smaller and weighs less than the average laptop. – A mobile phone that performs many of the functions of a personal computer. a powerful computer that can process large amounts of data and do a great amount of computation very quickly. a high-performance computer used for large information processing jobs. a mid-range computer that is intermediate in size, power, speed, storage capacity, etc., between a mainframe and a microcomputer. a central computer that provides information to other computers. a small computer designed for use by a single user at a time.
