Course Calendar

6.033 covers four units of technical content: operating systems, networking, distributed systems, and security. Lectures deliver the fundamental technical concepts; recitations show you how those concepts are applied to real systems. In tutorial, you'll learn communication skills to help you reason about systems, and describe and defend your own.

The calendar below includes lecture and recitation topics, along with due dates for all assignments. We also note when we expect various assignments to become available, and when we expect to deliver feedback (grades or otherwise) for each of assignment. The release dates for assignments and feedback are subject to small changes throughout the semester.

We will release the Spring 2021 assignments as the semester progresses. The contents of this calendar for days more than two weeks in the future may be missing or inaccurate.

Zoom links for all class activities are on Piazza.
