John: How does firewall know that you're socketing??

.

if (buffer_zone = = "set")

{

socket_set ();

}

else if (buffer_zone == "cleared")

{

socket_clear();

}

.

Me: There is an I/O port in your machine.

.

John : This I/O port is real.

.

Me: The data of this port will be moved to a register called buffer_zone.

.

John: If the register of buffer_zone is set, you're socketing.

.

John: If the register of buffer_zone is cleared, you're not socketing.

.

Me: Yes, That's the way which the firewall know that we're socketing.
