In this document, I am going to discuss about wireless and wired networks, but before I go further into these topics I would like to go a bit back to their parent types as you may not know that they are indeed a part of a bigger network, like a parent type, in other words, they are type of computer networks, which in turn is also a type of telecommunication network, which brings me into discussing a little about each of them, so you can get an idea of what exactly wireless and wired networks are, which is what this thesis is about. In this thesis, you would get to know the various types of network that exist.
