I moved in to an apartment where I can simply plug in my laptop to the internet by connecting it to a wall socket using an Ethernet cable.
I was wondering what is the difference between using this method and using a router? What about a modem, would this be present somewhere in the network?
I thought about security issues especially the firewall, but this is also available on the computer it self. Does it make much of a difference?
So what are the main differences? Are there any advantages or disadvantages between using and not using a router to connect to the internet?
