Can you help me understand the coefficients chart from a regression data screening output?

It is a model 1. For the constant, Unstandardized B is 2.254, Coefficients Standard Error is .256, t is 8.821, Sig is <.001. For Variable A, Unstandardized B is .113, Coefficients Standard Error is .055, Standardized Coefficients Beta is .172, t is 2.071, Sig is <.040, zero order is .170, Correlations partial is .172, part is .172. .For Variable B, Unstandardized B is .060, Coefficients Standard Error is .106, Standardized Coefficients Beta is .047, t is .567, Sig is .572, zero order is .038, Correlations partial is .048, part is .047.

What do these mean? How do I explain these results?
