AMOS is an extension of SPSS that is used for structural equation modelling, path analysis, and confirmatory factor analysis. AMOS is a visual-based program meaning you draw models graphically using simple drawing tools.

The video below (5:30") demonstrates the most basic uses of AMOS (and SPSS), using a simple linear regression for the example.
