5 computers connected to 1 Tower have different IP Addresses

how can 5 computers connected to 1 Tower have different IP Addresses ?
please help

You mean that different computer that are connected to one router have different ip's? If that is the case, then yes, to avoid conflict with same ip's which will result in no internet connection, the router must assign different ip's to different computers, so that ip addresses doesnt conflicts with each other.
