BEGINNER LEARNING PATH

Start From Zero and Build the Picture Properly

This path assumes you are new to infrastructure. It explains the words first, then the technology, then gives you something practical to do.

You need before starting

Basic computer use. No server, networking or cabling experience is assumed.

How to use the path

Work through the modules in order. Each module points to deeper material when you are ready.

End goal

You should be able to understand a small business IT environment and explain how its main pieces fit together.
