Computer Networking - July 2006

I'm reading on basic networking (newbie). Below is an excerpt of the book, or see www.geocities.com/vugh/question.txt

"For example, here’s how the network address is extracted from an IP address using the 20-bit subnet mask from the previous example:
144 . 28 . 16 . 17
IP address: 10010000 00011100 00100000 00001001
Subnet mask: 11111111 11111111 11110000 00000000
Network ID: 10010000 00011100 00100000 00000000
144 . 28 . 16 . 0 "

QUESTION: I'm confused why the third octet of the network ID (and IP Address) is 16. Isn't it supposed to be 32? Also the last octet of the IP Address, isn't it supposed to be 9 instead of 17?

I have a DELL laptop. I am trying to connect it to my LAN. I recently bought a PCMCIA wireless card for it. I followed the instructions, and it told me that after installing the CD I should put the card into the slot. I put it in, and the little "new hardward found" window did not pop up. Also, the power LED on the card is not lit up. The man at staples said that this card would work with my slot, but it doesn't seem to be.

I log onto my e-mail and click on pop up e-mail so i can read the details but instead of the page popping up and the results on the bar saying done, as usual, it'll say "pop up window was blocked" on the bar.

Whenever we take out the ethernet and plug in the usb cable, we restart the cable modem and we get a pc connection but no data bandwidth.
