    I like this analogy although now I'm thinking of being inside that apartment looking at an endless corridor with lots of doors. I cannot get out. I cannot get out! :) Commented Oct 30, 2012 at 22:13

    @Caleb A socket is the door of an apartment. But couldn't there be numerous sockets open at one port? Commented May 31, 2016 at 12:57

    @suhail Sometimes an apartment has more than one door. They all have the same apartment number, but they're different doors. Commented May 31, 2016 at 13:21

    This is an awesome analogy that clearly illustrates the scope of each layer of abstraction. You’re attempting to route traffic to a specific process running on a specific computer “somewhere” in the world 🗺. A delivery 🚚 driver cannot make good on his/her attempt at success without an accurate location and recipient (this is where we get into messaging, modeling, and delivery protocols). Thanks much! 👏🏿 🇺🇸 Commented Jan 22, 2020 at 19:21
  • @Caleb I agree with @suhail-gupta in that the door is implicitly talking about a unique door, while a door or any of the doors allow multiple doors, implicitly and explicitly, respectively. Commented Dec 14, 2020 at 22:51
