This is a quick-reference I made for some basic information about general computer networking and related concepts. It’s very far from complete, at time of writing.

I started this project as a means of reinforcing what I’ve learned while studying for a Cisco CCNA exam; I intend to keep building here as I learn more beyond the CCNA. Hopefully having all this information compiled in one place will be useful in the future, both for myself and possibly someone else.

To get started head to Networking, try the search bar, or check out the Glossary.

Note that I started this project after I began studying for the CCNA, so there are some topics which I have studied, but which are not represented on this site. I’ll try and circle back to them when I can, but in the mean-time there may be stubs (incomplete articles) and important topics that don’t have pages at all.
