Dear Experts,

Recently, I am taking tutorial of network class and there are a lot of network concept
i am getting confused, so I try to start to understand my home PC and network to solve my network concept problem.

At home, I get two PC with one at window 7 and the other at Window XP which is connected to one device we call ADSL something like the photo I include at web link

When I go to broadband internet, I log into window 7 or  PPPoE connection utility or
software with my login and password that is provided by my ISP company

After connection, I try ipconfig on cmd.exe,and I got the following message

PPP adaptor:
Ipv4 IP 219.77.x.x
subnet mask: 255.255.2555.2555
default gateway:

I am using auto configuration mode for the connection setup for external IP and  internet .

The question:
1- the  device of ADSL means  that is router plus modem, Right ?
2- router means network switches like the 4 ports in the photo attached, Right ?
3- DefaultGateway  or Gateway for my case that is refered to the my ADSL router, RIght
4- Why the default gateway is ?
5- I google default gateway, and found one article how to delete default gateway ( but it doesn't work, but is still there,why?
6- I also tried to use the command
netsp int ip reset c:\resetlog.txt  & netsp winsock reset c:\winsock.log and reset the computer and logging again, but is still there and not deleted, why ?

Hope you write more like for teaching student in a class for those questions
