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 minicomputers, microcomputers, mainframe computers and super computers.[1][2]

No one can say with certainty who coined the word 'superminicomputer' and to what systems he meant it to apply, but consensus is emerging that a supermini is nothing more than a minicomputer — a high-end mini, but a mini nonetheless.
