### Table of Contents

College Hall room 444 is the multi-media classroom
for the Department of Mathematics and Computer Science
with 30 PCs that run both UNIX and Windows 95.
There are an additional 17 similarly configured computers in the Alcoa Computer Lab
across from the elevators next to the department office
on the fourth floor of College Hall.
We will meet in the multi-media classroom for the weekly computer lab.
You may use this room and the Alcoa Lab to complete outside of class homework assignments.
There is a schedule outside of the multi-media classroom indicating
times when classes meet.
Note that many classes (especially mathematics classes) may not actually use the room
as scheduled,
so there is more open time in the lab than the schedule indicates.

If a class does come in to use the classroom,
you are expected to leave promptly.
