CS6/73201 "Advanced Operating Systems" 

            HOMEWORK #2
	
        Due in class 10/3/00

You are expected to provide clear, focused and convincing answers to the
questions. One line answers are probably too short and multiple page
answers are unnecessary. No additional credit will be given for
lengthy answers and too long answers may be penalized. In your answers
you should convince me that you understand the material, therefore,
simply copying from the textbook or class handouts would not suffice.
Use your own words.

The numbers in parenthesis refer to "Distributed Operating System"
(DOS) textbook. Each question is worth 5 points.
