Minicomputer is a class of multiuser computer that falls in the midrange computing series, between large multiuser mainframes and smaller personal computers. This terminology Minicomputer was used till 1990, since then it has changed to Netbook for marketing purpose. But classically there are differences between a Minicomputer and a Netbook.
Basics About Minicomputer
Minicomputer as a class are designed for commercial applications for Medium Data technology. From technical aspect minicomputer falls in the second and third generation of computers. The name minicomputer became popular in mid 1960s mainly with two features – usage of integrated circuits and improved design of the RAM. In order to create a smaller and more economical version of the mainframe, the American company has developed Digital Equipment Corporation (DEC) in the 1960s years the PDP-1 . This first mini computer was about the size of a cupboard.

The PC and servers we use today are clearly microcomputer. You can read about Mainframe computer here. More small version is Netbook. Basically the Operating System of a Minicomputer is actually used UNIX OS. Microsoft copied the idea of their Operating System from both VMS and UNIX. As at that time, Mainframe was quite costly and huge (practically mainframe is costly even today), the idea to market a small sized functional computer with integrated circuits came as a marketing idea.
We wrote about OpenVMS Operating System in detail, that article is very important for understanding the actually theft Graphical User Interface (GUI) of newer Windows Operating System. IBM still continues the production of Minicomputer, the latest being the Power series :
This is the basic reason why Apple typically avoided the usage of the word “Personal Computer”, instead uses the word “Mac” to define a smaller sized computing device those are actually less powerful than a Minicomputer.
