Answer 1

This is done with the help of transport layer(TCP/IP model).
It adds a source port number and destination port number to each of your request.

for eg- if you try to reach sololearn website. It is a secure web service(https). So transport layer will add some random source port number say 6000 and the destination port will be 443.

And now with the help of port number, data will be deliver to the correct source from the destination.

Different tabs in your browser will have different source port number.

Answer 2

Whenever browser sends a request to server, server response codes to browser.
