The XComputer applet illistrated very well the step-bystep process of a computer
as it executes a program. I liked how it went into detail on how each register
is populated with each fetch and execution cycle. Very good stuff for the
student to understand the computing process.

After completing chapter 4 in Foundations in Computer Science, which reviews
Assembly Language programming, I found this to be a good site that deals with
computer simulation. The designer has used commands that were not available on
the Pep 7 simulator used in class, which allows the reader to see the
differences within computer systems designed by different entities.
