How does a router work? -Think about routing the same way as mail delivery, we have an address we want to send a letter to, when we send it off to the post office, they get the letter and see, oh this is going to California, I'll put it on the truck going to California (I honestly have no idea how the postal system works). The letter then gets sent to San Francisco, inside San Francisco there are different zip codes, and then in those zip codes there are smaller address codes, until finally someone is able to deliver your letter to the address you wanted. On the other hand, if you already lived in San Francisco and in the same zipcode, the mail deliverer will probably know exactly where the letter has to go to without handing it off to anyone else. +Think about routing the same way as mail delivery, we have an address we want to send a letter to, when we send it off to the post office, they get the letter and see, oh this is going to California, I'll put it on the truck going to California (I honestly have no idea how the postal system works).

When we route packets, they use similar address "routes", such as to get to network A, send these packets to network B. When we don't have a route set for that, we have a default route that our packets will use. These routes are set on a routing table that our system uses to navigate us across networks. @@ -17,7 +17,7 @@ As packets move across networks, they travel in hops, a hop is how we roughly me Understanding the basic difference between Switching, Routing & Flooding?
