Systems, Networks, and Design: Welcome!

Welcome to Systems, Networks, and Design! 🖥️

A computer isn’t just a pile of parts — it’s a system, where every component depends on the others. In this course, you’ll stop seeing a computer as a mystery box and start seeing it the way engineers do: as a set of trade-offs, connections, and design decisions you can reason about, troubleshoot, and even improve.

What You’ll Learn

Systems Thinking

Trace how the CPU, RAM, storage, and bus move data — and how component choices shape performance.

Compatibility & Constraints

Understand how software requirements depend on hardware, and weigh trade-offs like cost, power, and speed.

System-Level Troubleshooting

Isolate hardware vs. software vs. network problems with systematic diagnostic strategies.

Networks

See how LANs, WANs, and the Internet connect devices, and how protocols move data between them.

Security & Reliability

Explore encryption, backups, and redundancy — the engineering behind trustworthy systems.
