Xbox is a game machine (a "games console") made by Microsoft. You connect it to a television, put in a game, and play with a controller in your hands. It first came out in 2001, and since then there have been many versions — Xbox 360, Xbox One, Xbox Series X and S — so when someone says "I got a new Xbox", they mean whichever version is current, not the first one.
