the professional operating systems were based on NT (New Technology). Starting with Windows XP (eXPerience), both home and professional editions are based on NT, even though the is dropped from their names. “NT” Version Home Editions Professional / Power User Editions 1 Windows 1.0 3.1 Windows NT 3.1 – 2 Windows 95 Windows NT 3.51 3 Windows 98 Windows NT 4.0 4 Windows Millennium Windows 2000 Windows XP Professional Edition Windows XP Home Edition 5 Windows Server 2003 Windows Home Server Windows Server 2003 R2 6 Windows Windows Server 2008 Windows 7 7 Windows Server 2008 R2 Windows Home Server 2011 Windows 8, 8.1 Windows Server 2012 8 Windows Phone 8 Windows Server 2012 R2 Windows RT Windows 95, 1995 Microsoft introduced second Windows operating system. This time, the GUI was very similar to that of the Macintosh. The appearance of the GUI would not radically change until Windows 8. Tianhe-2 Supercomputer, 2013 In November 2012, the fastest computer in the was officially the Titan made by the US Department of Energy. However, in June 2013 Supercomputer China’s Tianhe-2 took the title. It can perform 33,860,000,000,000,000 floating point operations in 1 second. This is almost twice as fast as the Titan. Remember that the ENIAC could perform 385 multiplication operations in a second. If we ignore the fact that a floating point operation is more complicated than a simple multiplication operation, it would still mean the Tianhe-2 is at about 88 trillion (88,000,000,000,000) times as fast as the ENIAC.
