Introduction

Welcome back to my journey through the TryHackMe Pre Security path!

In our previous walkthrough, Computer Types, we explored how hardware form factors have evolved past traditional desktops, scaling from massive enterprise data center servers down to tiny, hidden embedded systems in everyday household appliances.

But how do these diverse computing devices actually talk to one another? How does a smartphone request data from a headless server thousands of miles away?

To bridge that gap, we are diving into the next room of the Computer Fundamentals module: Client-Server Basics. In this guide, we will break down the underlying architecture of modern network communications, map out the mechanics of network requests, and look at how protocols, ports, and IP addresses handle global web traffic.

As usual, you can catch up on our last article of Computer Types by clicking the banner below.
