Tagged means the VLAN dot1q header is going to be added to the frame and sent to the downstream device. This is normally done to trunk interfaces (Cisco terminology "Trunk") on a switch so it knows what VLAN the frame belongs to.
Untagged means the frame gets sent out the port with no VLAN information. You would do this on an access port (Cisco terminology)
Normally, you will probably set both of these as tagged interfaces so you can use multiple VLANs per interface instead of building a new interface for each and every VLAN if it was an untagged interface.
