Access-List and Distribute-List

Access-List and Distribute-List
Access-Group in/out and Distribute-List in/out

I have seen examples where they use an Access-List to determine the traffic to be Permitted or Denied, then you go to the interface and they use the Access-group command to alllow in/out the traffic

I also have seen Distribute-List in /out that does pretty much the same thing. I would like to know where each command differs from other.

Access-group in/out can be used at the interface level only
Distribute-List in/out, at interface level and global config level

Thank you

A distribution list is actually a misnomer and does not really belong here A distribution list is really only a command that uses route-maps or ACLs to perform filtering of routing information advertised or received within a particular routing protocol. It is not a standalone filtering mechanism similar to ACLs/route-map.

I was exactly at that link before I posed the question..
it is a little bit helpful...but they don't elaborate on the difference..for instance Distribute list can be use the same way as the Access-group when applied at the Interface level..

I want to know the similarities and the differences between..
Access-Group and Distribute-List

Can you provide an example of the distribute list command being used at the interface level?
