Question 1
Why was the Sun installation done with a pretty graphical interface but the linux one done with an ugly text-based interface? Say something about hardware expectations. (One sentence.)

Question 2
Use dejanews http://www.dejanews.com to determine what X server you need for linux on your Dell Latitude laptop. (Give the words you used for your query, and the name of the X-server.)

Question 3
Your current directory is /. Give a UNIX command sequence that will count the number of files (don't worry about ones with names beginning with a '.') in the directory /tmp/foo. (The output should just be the number of files [and perhaps some whitespace] --- no other numbers or words.)
