CS 201: Data Structures
Think back to your favorite assignment from Introduction to Computer Science. Did you ever get the feeling that “there has to be a better/smarter way to do this problem”? The Data Structures course is all about how to store information intelligently and access it efficiently. How can Google take your query, compare it to billions of web pages, and return the answer in less than one second? How can one store information so as to balance the competing needs for fast data retrieval and fast data modification? To help us answer questions like these, we will analyze and implement stacks, queues, trees, linked lists, graphs, and hash tables. Students who have received credit for a course for which Computer Science 201 is a prerequisite are not eligible to enroll in Computer Science 201.
Prerequisites: Computer Science 111 or instructor permission 6 credits; Formal or Statistical Reasoning, Quantitative Reasoning Encounter; offered Fall 2019, Winter 2020, Spring 2020 · Sam Tucker, Amy Csizmar Dalal, Anna Rafferty, David Musicant

Prerequisites: Computer Science 201 or instructor permission 6 credits; Formal or Statistical Reasoning; offered Winter 2020 · John Ellinger 
CS 330: Introduction to RealTime Systems
How can we prove that dynamic cruise control will brake quickly enough if traffic suddenly stops? How must a system coordinate processes to detect pedestrians and other vehicles to ensure fair sharing of computing resources? In realtime systems, we explore scheduling questions like these, which require provable guarantees of timing constraints for applications including autonomous vehicles. This course will start by considering such questions for uniprocessor machines, both when programs have static priorities and when priorities can change over time. We will then explore challenges introduced by modern computers with multiple processors. We will consider both theoretical and practical perspectives.
Prerequisites: Computer Science 201 and Computer Science 202 (Mathematics 236 will be accepted in lieu of Computer Science 202). 6 credits; Formal or Statistical Reasoning; offered Winter 2020 
CS 331: Computer Networks
The Internet is composed of a large number of heterogeneous, independentlyoperating computer networks that work together to transport all sorts of data to points all over the world. The fact that it does this so well given its complexity is a minor miracle. In this class, we’ll study the structure of these individual networks and of the Internet, and figure out how this “magic” takes place. Topics include TCP/IP, protocols and their implementations, routing, security, network architecture, DNS, peertopeer networking, and WiFi along with ethical and privacy issues. Prerequisites: Computer Science 201 or instructor permission 6 credits; Formal or Statistical Reasoning; offered Winter 2020 · Amy Csizmar Dalal

CS 332: Operating Systems
If you’re working in the lab, you might be editing a file while waiting for a program to compile. Meanwhile, the onscreen clock ticks, a program keeps watch for incoming email, and other users can log onto your machine from elsewhere in the network. Not only that, but if you write a program that reads from a file on the hard drive, you are not expected to concern yourself with turning on the drive’s motor or moving the read/write arms to the proper location over the disk’s surface. Coordinating all this hardware and software is the job of the operating system. In this course we will study the fundamentals of operating system design, including the operating system kernel, scheduling and concurrency, memory management, and file systems.
