Yes--they involved all parts of society and contained a whole government focus on war.
Both WW I and II included an all out government effort for the wars including rations, propaganda, and funding. The home front had to sacrifice and work to support the war and of course some had to actually fight on the front. All members of society were asked to contribute to the war.

No. This was called World War 2 because it was the second war that was held on such a large scale that it encompassed all the great forces of the entire world, from Europe to America to Asia and Australia. Before it was World War 1, which wasn't numbered since nobody expected world war 2 to happen, so it was called the Great War.
