what is the difference between the two concepts of IP overlapping and IP conflict?

IP overlapping is commonly caused by attempting to configure interfaces on a router or switch and attempting to use addresses that are not the same but are in the same subnet. For example
interface fast0/0
ip address 192.168.2.25 255.255.255.0
interface fast0/1
ip address 192.168.2.50 255.255.255.0
In this case the addresses overlap and IOS will not accept the second set of commands.
IP conflict is when you attempt to use an IP address on a device and some other device in the network already is using that address.
So one is an issue on a single device when 2 interfaces attempt to use addresses that are in the same subnet and the other is an issue between 2 devices both of which are attempting to use the same address.
