I want to create a reference to everything I read on the internet during my network (CCNA) study, so I make that repo to organize the information I read and to be a good reference for others as well. For now, it will contain a lot of updates, so if you are going to start studying from it, it's better to study the topics specified in the table of contents.

When will I finish it? Nobody knows, I am a lazy person who finishes a series in a day and can't finish a page of a book xD.

A Note To You

You may feel lost while you study, or that you don't understand this part well, I've been through this too and from my experience everything seems vague at first it will become clear as you study, so the more you study, the more you understand networking well. Also, you may meet things that you think are useless, never think so, everything you know will help later.

How did this start ?

Sections

1. Introduction to Computer Network (It's pretty mush finished)
2. Routing (Under working)
3. Switching
