1.	How can we differentiate between mini computer and mainframe computer
Answer» Main difference between them is physical size and at the time processing power, mini COMPUTER think PDP11 about as large as a washing machine, freezer. Main frame think REALLY big computer it could easily take up the space of a smaller room, lots of storage, power usage, often redundant in hardware. Mini computer and main frames has been replaced by PCs and virtualization. You get the same high availability as a main frame with several PCs running virtualization software in a cluster together with redundant NETWORKING and SAN storage. So today you can get more processing power from virtualized PCs than expensive proprietary main frames at a CHEAPER prize. Feature wise in the past main frame computers was way AHEAD of PCs, as they had virtualization, redundant file systems etc.
