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.
The Great Depression, which began in 1929, did not end until the United States was actively engaged in World War II.Some economists believe that the country's entrance into the war -- which spurred increased industrial and labor production for the war effort -- was the primary reason the Depression ended.n this theory, economists look at how World War II introduced new sectors to the economy that previously did not exist. The creation of the aerospace industry, which was quite small before the war, is a prime example.
