Exercise 1

Due Feb 12 in class.

1. Quest 2.1(b) from text page 37.

2. Consider the situation where we are developing
   a soft real-time scientific application. For software fault
   tolerance, we are considering N-Version Programming and Recovery
   Block. Your task is to compare and contrast the two approaches in
   the context of our application. Write a report (approx. 5 pages
   double spaced) that details your analysis and recommendations. A
   simple prototype of both techniques would help support your claims
   and recommendations.
