Fundamentals
How a computer and a server actually work, before you touch a terminal.
What you'll actually learn
Every other track on this platform assumes you know what actually happens between pressing a key and something appearing on screen — this one is where that assumption becomes true. You'll see how a CPU, memory, and storage actually cooperate to run a program, and what a "server" really is underneath the word: not a mysterious box in the cloud, but the same kind of machine sitting in front of you, just reachable over a network.
What you'll be able to do
You'll be able to explain, in concrete terms, what's actually happening when a program runs slow because it's waiting on disk instead of CPU, or when "restart the server" actually fixes something — the baseline mental model every other track on this platform, from Linux to networking to cloud, builds directly on top of.
