CS 320: Introduction to Computer Systems at UW-Madison

CS 320 at the University of Wisconsin-Madison, titled “Introduction to Computer Systems,” is a core undergraduate course that bridges the gap between high-level programming concepts and the underlying hardware and software that make them work. It delves into crucial topics like memory management, concurrency, and system calls, providing students with a foundational understanding of how computer systems operate.

Course Overview

This course exposes students to the internal workings of computer systems. Unlike programming courses that focus solely on application development, CS 320 explores the intricate layers connecting software to hardware. Expect to learn about low-level programming in languages like C, which necessitates careful memory management and a deeper understanding of system resources. The course typically covers the following key areas:

• Memory Management: Understanding how memory is allocated, deallocated, and managed by the operating system. This includes topics like virtual memory, paging, and segmentation.
• Concurrency: Exploring how multiple processes or threads can execute concurrently, including concepts like synchronization, mutual exclusion, and deadlocks.
• System Calls: Learning how user programs interact with the operating system kernel through system calls, enabling access to hardware resources and system services.
• File Systems: Understanding the organization and management of files and directories within a computer system.

Prerequisites and Difficulty

CS 320 usually requires a solid background in programming, typically gained through introductory computer science courses. A strong understanding of data structures and algorithms is also beneficial. The course is considered challenging due to its focus on low-level details and the need to write code that interacts directly with the operating system. Debugging can also be more complex compared to higher-level programming.

Programming Languages and Tools

The primary programming language used in CS 320 is typically C. Students will also become familiar with using command-line tools and debuggers like GDB to analyze and troubleshoot their code. Knowledge of shell scripting may also be helpful. The course often involves assignments that require building system-level components from scratch, further solidifying understanding.

Why is CS 320 Important?

Understanding computer systems is fundamental for any aspiring computer scientist or software engineer. CS 320 provides the knowledge necessary to write efficient, reliable, and secure software. It also prepares students for more advanced courses in operating systems, networking, and security. Having a firm grasp of these concepts allows you to optimize code for performance and avoid common pitfalls related to memory leaks or concurrency issues. Furthermore, this understanding helps in comprehending how different software interacts with the operating system, which is crucial for system programming.
