Your guide to the home network

This website has been written as a guide to how computer networks work on a small scale such as a typical home network.

Here you will find all of the basic knowledge that is required to understand how network communication and computer networks in general function. By knowing how a network normally behaves, it is also much easier to figure out why things sometimes aren’t working the way they should.

The website is meant to be fairly easy to understand. It should not require any specific skills other than some general computer knowledge and an interest in figuring out how things work. If you ever tried to tinker with your home network or wondered how something network related works, then this website is for you!

I also use pictures and diagrams throughout the text to explain the topics. Here are a few examples from various sections of the website:

Even if each chapter covers a lot of information we have tried to keep it as simple as possible. Sometimes we have chosen to simplify things a little bit. This could be done for example by excluding more advanced parts of a subject or by moving them to later more advanced topics that you can delve into. However even when the information has been simplified it is never presented in an incorrect way.

The sections of the web page are written in succession, following the order of the top menu. You may of course read through the sections in any given order, but if you find some area that you do not completely grasp then you might have to go back to an earlier chapter to find out more about previously presented topics.
