Xbox is the predecessor to Microsoft's Xbox 360 console.
The Xbox 360 is the successor to Microsoft's Xbox video game console, developed in cooperation with IBM, ATI, Samsung and SiS.
Xbox Live Gold has the same features as Silver, plus online game playing capabilities.
Backward compatibility is achieved through software emulation of the original Xbox.
Up to four controllers are supported by the Xbox 360, in the wireless form. However, there is a maximum of three wired controllers, as the Xbox 360 only has 3 USB slots.
