Abstract: 

Let R and S be reduced rings with identities whose idempotents are central, and let M be an (R, S)-bimodule such that annr (M)=0. In this paper, we determine first the structure of automorphisms of the triangular ring
T= [ R    M]

      0     S

and then, for all automorphisms α ,β of T we determine the structure of (α,β)-derivations of T.
