On Airport Express, under Wireless tab, what is the difference between join and extend?

I have a Time Capsule that is my primary wireless router and an Airport express that I have had configured to Extend my wireless network. I see there is also an option to Join a wireless network but I am not finding anything to describe the difference between these two options. Also, when in Extend mode, is the Ethernet port on the Airport Express active? I have a TV I want to be able to connect.

Thanks,

MacBook Pro with Retina display, OS X Yosemite (10.10.4)

Extend means you are using a wireless access point to extend the wireless range. This would usually be done using an Airport Express. Joining a network means you are simply connecting to the existing network. It is sometimes called "Bridge Mode." You can only Extend an Apple router with another Apple Airport device.

There is no such thing as Extending an Ethernet connection. So on an Airport Express you can connect wirelessly to an existing network and then connect an Ethernet device to the Ethernet port. The AEX becomes a wireless access point.
