I was looking for what port is on many websites, but i am not sure if i found what i want. My questions is:
- 1) What is a port? Is that a piece of code in my Windows? As i found on (en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers#Well-known_ports) port 80 somehow related to http, and port 443 to htttps but how exactly?
- 2) How can port know to which program to sent information? For example i am listening music on Youtube in Google Chrome and playing agar.io on Internet Explorer. How does port know how to handle information that flows in my computer?
- 3) If i will decide to make my own site, which port can/should i use? Doesn't matter? Or some specific?
