Undergraduate / Computer Science Major (BS/BA) / CS Core, Breadth, and Depth RequirementsCS Breadth: Systems
The courses below fulfill the Breadth: Systems requirement in computer science.
Overview of digital logic design. Implementation technologies, timing in combinational and sequential circuits, EDA tools, basic arithmetic units, introduction to simulation and synthesis using VHDL.
This course introduces students to the key features of programming languages. Students implement a series of interpreters that nail down the precise details of how various aspects of programming languages behave. Students are assumed to understand trees and (mathematical) functions that process them; the course builds up to the features of real programming languages from there.
The compiler is the programmer's primary tool. Understanding the compiler is therefore critical for programmers, even if they never build one. Furthermore, many design techniques that emerged in the context of compilers are useful for a range of other application areas. This course introduces students to the essential elements of building a compiler: parsing, context-sensitive property checking, code linearization, register allocation, etc. To take this course, students are expected to already understand how programming languages behave, to a fairly detailed degree. The material in the course builds on that knowledge via a series of semantics preserving transformations that start with a fairly high-level programming language and culminate in machine code. This course satisfies the project requirement.
Data models and database design. Modeling the real world: structures, constraints, and operations. The entity relationship to data modeling (including network hierarchical and object-oriented), emphasis on the relational model. Use of existing database systems for the implementation of information systems. This course satisfies the project requirement.
A top-down exploration of networking using the 5-layer model and the TCP/IP stack. HTTP, FTP, DNS, BSD Sockets, concurrent servers, checksums, reliable transport with stop-and-wait, go-back-n, selective repeat, flow control, congestion control, TCP, unicast routing, multicast routing, router architecture, IP, IPv6, IP multicast, MAC protocols and LANs, Ethernet , wireless networks, and network security. Over the course of the quarter, students build web clients and servers, a fully compatible TCP/IP stack that can run them, and evaluate routing protocols in simulation. This course satisfies the project requirement.
A fundamental overview of operating systems. Topics covered include: Operating system structures, processes, process synchronization, deadlocks, CPU scheduling, memory management, file systems, secondary storage management. Requires substantial programming projects. Approved for Systems Breadth and Depth in the CS curriculum in McCormick and Weinberg This course satisfies the project requirement.
Basic principles behind distributed systems (collections of independent components that appear to users as a single coherent system) and main paradigms used to organize them. This course satisfies the project requirement
Structure and timing of typical microprocessors. Sample microprocessor families. Memories, UARTS, timer/counters, serial devices and related devices. MUX and related control structures for building systems. Interrupt programming. Hardware/software design tradeoffs.
The past decade has seen an explosion in the concern for the security of information. This course introduces students to the basic principles and practices of computer and information security. Focus will be on the software, operating system and network security techniques with detailed analysis of real-world examples. Topics include cryptography, authentication, software and operating system security (e.g., buffer overflow), Internet vulnerability (DoS attacks, viruses/worms, etc.), intrusion detection systems, firewalls, VPN, Web and wireless security. Students with good performance in the class will be awarded researchship in the academic year and/or the summer. This course can help satisfy the project course requirement for undergraduates and satisfy the breadth requirement in computer systems for system Ph.D. students. This course satisfies the project requirement
This course will focus on remote computer penetration (hacking). The class will introduce basic theory for many different types of attacks; then we will actually carry them out in 'real-world' settings. The goal is to learn security by learning how to view your machine from a hacker's perspective. In addition, we encourage students to participate in the UCSB International Capture the Flag Competition. Capture the Flag is a network security exercise where the goal is to exploit other machines while defending your own. In fact, this course should prepare you for any one of many capture the flag competitions that take place year round.
This course will provide coverage of the basic hardware and software platforms for sensor networks and will address in detail several algorithmic techniques for data routing, querying processing, and topology management. The students will obtain hands-on experience through programming projects involving TinyOS or MantisOS, running on Telos/MicaZ platforms. In addition, a number of prototype systems, such as TinyDB will be studied, in the context of various application domains of sensor networks.
In this seminar, we will survey the fundamentals of data science by reading state of the art research papers in this area. This class will cover the basics of how to manipulate, integrate, and analyze data at scale. To receive credit, students must give in-class presentations and complete a final project.
Introduction to the design and evaluation of embedded systems, with emphasis on the system-level aspects of embedded systems. Topics include modeling (models of computation and models of communication), survey of embedded system hardware, software and operating system issues specific to embedded system design, mapping specifications to hardware, and testing and evaluation of embedded systems.
The development of low-level software such as drivers, kernels, hypervisors, run-times, system libraries, JITs, and firmware is very different from the development of applications. The goal of this class is to teach students how such development is done, both in terms of the modes of thinking needed to design, implement, debug, and optimize low-level software, and in terms of how to leverage representative, widely-used tools to do so. Some of the techniques the class covers are also used in the design and optimization of the performance-critical parts of applications.
The Internet has evolved from a small, well controlled, and trusted network, into a gigantic, loosely controlled, and highly uncooperative infrastructure of astonishing scale and complexity. Not only that different hosts or networks have divergent functional or economical interests, but the Internet has become a “playground” for malicious denial-of-service attackers of all kinds. Moreover, its everyday operation is often poorly understood, and existing solutions to many of the classical challenges remain unsatisfactory. Hence, the design of Internet is far from complete, and it is certain that it will continue to change. This class is intended to help you understand how and why, by letting the Internet to become your “playground” for a quarter.
The bulk of the time in this class examining a virtual machine monitor (VMM) in depth, at the source code level. The course explains the hardware/software interface of a modern x86 computer in detail. A VMM is an operating system that is implemented directly on top of the hardware interface, and itself presents a hardware interface to higher-level software. Students will also acquire valuable kernel development skills. This course satisfies the project requirement
Cybercrime has exploded over the last decade. In this course, we will start with the basic concepts of network security, then focus on security challenges of network and distributed systems as well as the counter-attack approaches.
