ELI5: Why does my internet connection start working again if I unplug it and then plug it back in?

This even works for just my computer's wireless connection. If I disconnect it from the router and then reconnect it some how works again. I just don't get it.

Many things could be wrong when internet doesnt work, therefore there are several reasons this can fix it.  

One cause: To be a member of a network, your computer and your cable modem needs an address, called an IP address. When joining a network, the computer should automatically receive one from your modem, and the modem should receive one from your internet provider.. But sometimes it does not, or the one it has expires, and for wharever reason, it doesnt ask for a new one. Turning the connection off and on again (or unplugging and replugging) causes your computer to contact the network and ask for a new address.
