Windows 10 is the latest iteration of Microsoft's operating system. Desktops with Win 10 and previous versions are what most people typically use, so you'll be assured of the best compatibility and widest selection of third-party software. This also applies to browser plugins, since some only work with Windows. Apple's OS X is currently up to version 10.11 (El Capitan).
World War II (WWII), also called the Second World War, was a global war. It took place from 1939â1945. Most of the world's countries, including all the great powers, fought as part of two military alliances: the Allies and the Axis. The war was fought as a total war, meaning all resources a country had were used in the war, even those that didn't belong to the army, such as factories.
In the late 1980s, the Cold War came to a dramatic end. The economies of nations behind the Iron Curtain were in trouble. People in East Germany, for instance, could see the prosperity and wealth of their West German neighbors. In Russia, there were long lines of people waiting to buy food.
