CS 352: INTERNET TECHNOLOGY (FALL 2025)

The Internet is a global communication system through which billions of users/devices communicate with each other. It powers everything from social media and streaming to e-commerce, cloud computing, and the Internet of Things (IoT). Understanding how the Internet works is essential for designing, building, or managing the technologies that drive our digital world. 

CS 352 (Internet Technology, also known as undergraduate-level Computer Networks) will cover various technologies related to the Internet, such as Domain Name System (DNS), TCP/UDP protocols, packet routing algorithms, medium access protocols, and wireless communications. Our learning will be grounded in the widely used five-layer TCP/IP network model, providing a structured framework to understand how these technologies operate and interact: 

• L5: Application Layer

• L4: Transport Layer 

• L3: Network Layer

• L2: Link Layer  

• L1: Physical Layer 

The course will also explore cellular/mobile (e.g., 5G) networks, Wi-Fi systems, IoT and satellite networks, Software-Defined Networking (SDN), and other emerging innovations. 

Prerequisites: Students need to have some basic knowledge of Mathematics for Computer Science (e.g., Linear Algebra, Calculus, and Probability Theory), Data Structures, and System Programming.  

Recommended Textbook: James F. F. Kurose and Keith W. Ross, "Computer Networking: A Top-Down Approach Featuring the Internet", 9th (or any recent) edition.
