its a switch
It is a network adapter whether it is wireless or wired type.
A switch is a network connectivity device and a host is a computer system (client) on a network.
This device is called a ROUTER. Routers are by default configured to not pass the broadcast traffic to another networks to which it connects. But by some means it could be also a SWITCH - sometimes it can be configured to filter different type of network traffic.
