But in the year 1990, Microsoft Windows * moved to a stable platform 32-bit Windows was supported Ethernet and TCP / IP takes as a communication technology. Dit betekende providers of operating systems can build their products on top of a low-cost, high performance platform, resulting in systems that are not only very rich and capable on their own, but it can also easily interface with existing enterprise dates as managing the business.
