more exactly the difference between "Qualcomm/Atheros AR8161/8165 PCI-E Gigabit Ethernet Controller" and "Atheros Communications AR9565 Wireless Network Adapter"

I mean the way they are built. For example: Do they both have the same components/modules on them? How are they related or different? Is wireless card the same as ethernet controller just without a socket for the cable (and connections to an antenna instead)?
