How Is a Ceasefire Different From an Armistice?

News reports often use “ceasefire” and “armistice” as if they mean the same thing, but they seem to carry different weight. Is the difference mainly legal, or does it also affect what happens on the ground?

I’m curious about the distinction between a ceasefire and armistice, especially whether either one formally ends a war or simply pauses fighting. Historical examples would help clarify how these terms are used in practice.
