Resilience is the ability of not having a (catastrophic? depends on who is defining) failure when the situation changes. Resistance is the ability of not requiring any adjustment to avoid a failure when the situation changes.

A machine that has very thick parts is resistant. A machine with redundant parts that you can fix is resilient. A machine whose builder is always learning from failure and improving is antifragil.
