The English name Germany comes from the Latin Germania. Julius Caesar adopted it from a Gallic term for the peoples west of the Rhine river, it's likely that it meant "neighbor".
The Germans refer to their country as Deutschland, which is derived from the Old High German diutisc, or similar variants from Proto-Germanic *Þeudiskaz, which originally meant "of the people". This in turn comes from a Germanic word meaning "folk" (leading to Old High German diot, Middle High German diet), and was used to differentiate between the speakers of Germanic languages and those who spoke Celtic or Romance languages. These words come from *teuta, the Proto-Indo-European word for "people" (Lithuanian tauto, Old Irish tuath, Old English þeod).
The Italian word for the Germans was tedesco or Tedeschi (variants: todesco, tudesco, todisco) and comes from the same Old High German root, although not the name for "Germany" (Germania). The British soldiers fighting in Italy in WW2 shortened this to Teds.
