A minicomputer, a term no longer much used, is a computer of a size intermediate between a microcomputer and a mainframe. Typically, minicomputers have been stand-alone computers (computer systems with attached terminals and other devices) sold to small and mid-size businesses for general business applications and to large enterprises for department-level operations. In recent years, the minicomputer has evolved into the "mid-range server" and is part of a network. IBM's AS/400e is a good example.

In an ascending hierarchy of general computer sizes, we find:

* The embedded systems programming computer, which is embedded in something and doesn't support direct human interaction but nevertheless meets all the other criteria of a microcomputer
* The microcomputer
* The workstation, as used to mean a more powerful personal computer for special applications
* The minicomputer
* The cluster, which is often several microcomputers or larger computers that share a workload and back each other up
* The mainframe or mainframe computer, which is now usually referred to by its manufacturers as a "large server"
* The supercomputer, formerly almost a synonym for "Cray supercomputer" but now meaning a very large server and sometimes including a system of computers using parallel processing
* The parallel processing system, which is a system of interconnected computers that work on the same application together, sharing tasks that can be performed concurrently

A supercomputer is a computer that performs at or near the currently highest operational rate for computers. A supercomputer is typically used for scientific and engineering applications that must handle very large databases or do a great amount of computation (or both). At any given time, there are usually a few well-publicized supercomputers that operate at the very latest and always incredible speeds. The term is also sometimes applied to far slower (but still impressively fast) computers. Most supercomputers are really multiple computers that perform parallel processing. In general, there are two parallel processing approaches: symmetric multiprocessing (SMP) and massively parallel processing (MPP).

A microcomputer is a complete computer on a smaller scale and is generally a synonym for the more common term, personal computer or PC , a computer designed for an individual. A microcomputer contains a microprocessor (a central processing unit on a microchip ), memory in the form of read-only memory and random access memory , I/O ports and a bus or system of interconnecting wires, housed in a unit that is usually called a motherboard .

In an ascending hierarchy of general computer sizes, we find:

* An embedded systems programming computer, which is embedded in something and doesn't support direct human interaction but nevertheless meets all the other criteria of a microcomputer
* Microcomputer
* workstation , as used to mean a more powerful personal computer for special applications
* minicomputer , now restyled a "mid-range server"
* mainframe or mainframe computer, which is now usually referred to by its manufacturers as a "large server"

Hi,

Well Most of those terms are irrelavent nowdays but basically, the distinguishing features are as follows:

Mainframes are computers used mainly by large organizations for critical applications, typically bulk data processing such as census, industry/consumer statistics, ERP, and financial transaction processing.

The term originated during the early years of computing and referred to the large mechanical assembly that held the central processor and input/output complex. Later the term was used to distinguish high-end commercial machines from less powerful units which were often contained in smaller packages. Today, this term almost exclusively refers to IBM System z9 mainframes, the lineal descendants of the System/360.

Minicomputer is a largely obsolete term for a class of multi-user computers which make up the middle range of the computing spectrum, in between the largest multi-user systems (traditionally, mainframe computers) and the smallest single-user systems (microcomputers or personal computers). More modern terms for such machines include midrange systems (common in IBM parlance), workstations (common in Sun Microsystems and general UNIX/Linux parlance), and servers.

Although there is no rigid definition, a microcomputer (sometimes shortened to micro) is most often taken to mean a computer with a microprocessor as its CPU. Another general characteristic of these computers is that they occupy physically small amounts of space. Although the terms are not synonymous, many microcomputers are also personal computers (in the generic sense) and vice versa.

A supercomputer is a computer that leads the world in terms of processing capacity, particularly speed of calculation, at the time of its introduction. The term "Super Computing" was first used by New York World newspaper in 1920 to refer to large custom-built tabulators IBM made for Columbia University.
