If a type implements a particular interface, then it is making a promise to the rest of .NET that it supports a certain feature.

IComparer	Compare(first, second)	This defines a comparison method that a secondary type implements to order or sort instances of a primary type
IDisposable	Dispose()	This defines a disposal method to release unmanaged resources more efficiently than waiting for a finalizer
