COMP 150-IDS:Internet-scale Distributed SystemsLessons from the World Wide Web

A course on system design principles

© 2010 Noah Mendelsohn5

The course will explore several threads in parallel:

1. We will look top-down at various principles of distributed system architecture

2. We learn to build Internet clients and servers that communicate

3. We will contrast several styles of distributed systems

4. We will explore the history of computer networking, and explain why the Web is designed the way it is

A course on designing Web applications (COMP 20/120)

An comprehensive OS course (COMP 111)

An comprehensive networking course (COMP 112)

A programming languages course (several)

However...we will explore issues relating to all of those!

What this course is not

We are looking for Teaching Assistants!

• Help students with programming assignments

• Help me to test student submissions

• Hired by the hour (I think!)
