Does our internet browser has port ? If yes How to check it?

Answer 1

no browsers don't have ports but TCP/IP have ports..
like for http www have 80, telnet has port 23, SSH has 22 and FTP has 20/21 and the list goes on..

Answer 2

then ho do web server know where to send response (on which browser if client has more than one browser)

Answer 3

they don't give a damn to browser.. you r fetching details from a site which has a url and has a http protocol so it has 80/8080 port.. so the cliemt url communicates to the server on the same port.. and then the cliemt communicates to FTP port to its database.. and gets info and sends the info back to the client on the same port

Answer 4

thanks man

Answer 5

like u can even use dos to communicate to websites ... as telnet does.. and major of Ddos attacks can be done by dos.. and checking vulnerability of a site can be done by telnet just fetching the site on the port
