Minicomputers are computers that are somewhere in between a microcomputer and a mainframe computer. In times past, such devices were typically stand alone computers that were ideal for use by small and mid-sized businesses that needed more power and memory than could be obtained with microcomputers, but did not have a need for the resources provided by mainframes. More recently, the term is often used for a server that is part of a larger network.

In the early years of computer technology, a hierarchy of computer sizes and types was used to define the level of operation needed for different types of applications. The levels ranged from the embedded systems that functioned more or less automatically, to parallel processing systems that were capable of supporting a huge network of interconnected computers and performing a wide array of tasks simultaneously. The minicomputer tended to be somewhat low on the hierarchical listing, in that the device was considered to be limited in ability.


Its original structure was a simple computer system that was equipped with essential programs and functions that would handle simple tasks, such as word processing. The computer was equipped with terminals that made it possible to attach peripheral devices to the system, such as a printer, but it usually did not have hardware or software that allowed the device to be integrated into a larger network. If there was no need to use comprehensive applications or interact with other systems, however, the system was often sufficient.

Over time, the concept has become somewhat obsolete. As technology has continued to evolve, many tasks that were once the exclusive province of the larger and more powerful mainframe computers has been assumed by the workstation computers of today. Mainframes are still used, although their purpose and function is often associated with the role of a large server to support a network of workstations. In like manner, the minicomputer has morphed into a server that is ideal for smaller and more localized networks.

@panda2006, minicomputers are actually more like databases or things for storing memory than conventional personal computers or laptops, whereas a netbook computer is a laptop computer that is smaller and has fewer features.

I'm curious then, are Minicomputers similar to netbooks?
