As we have stated at the start, the goal of this little book is to help students gain experience and confidence in creating their own operating system or similar computer systems in their future career. As illustrated in the table above, each project helps students understand how to create one piece of egos-2000. Except for few applications under apps, students finish reading all the code of egos-2000.
