Exploring Digital Information Technologies for Non-Engineers
Fall 2025

Course Description

This course will give students from outside of Engineering an under-the-hood view of 12 important technologies that will impact their daily lives in the next decade.

• WiFi and Cellular networks
• Internet
• File Systems
• Search Engines
• Recommendation Engines
• Social Networks
• Machine Learning
• Authentication and Security
• Computer Vision and Image Processing
• Speech Recognition and Natural Language Processing
• Self-driving Cars
• Augmented and Virtual Reality

For each technology, students will

1. understand the core technical challenges in realizing the technology
2. gain intuition on how the challenges are being solved
3. appreciate how such technologies translate to business and revenue, and
4. identify implications in areas such as privacy, fairness, policy, ethics, and other paradigm shifts.

Technical subjects to be considered include basics of sensing, computing, communication, and control, the four pillars of technology. To help students better relate to the topics discussed in the course, each technology will highlighted one or more well-established companies using/promoting the technology (e.g., Comcast, ATT, Microsoft, Google, Amazon, Meta, Verisign, ADT, Apple, OpenAI, Tesla, etc.).
