What do the wireless card and wireless router use for? Could I buy just the wireless card? And what do "Dell Wireless 355 Bluetooth Internal (2.0 + Enhanced Data Rate) use for? One more question what is the different between 1GB and 2GB Shared Dual Channel DDR2 SDRAM at 533MHZ, 2 DIMM?
The most important questions are the first and the second question. Please answer them first. Thank you so much.

hey
the wireless card is in your laptop and lets you RECEIVE wireless internet (provided someone is broadcasting)
the wireless router is external to your laptop and is the modem you use to BROADCAST the internet to your laptop.
So you can get internet with just the wireless card, but only if you are near a n internet source e.g. a broadcast from an internet cafe or other 'hotspot'
hope that helps. -
if you are talking about access in your home where there is no existing wifi network set up and you current have a broadband connection, then yes, you need a wifi router.
if you are talking about accessing the internet where there is already wifi set up (work, school, library, etc), then no, you do not need wifi.
Bluetooth is for connecting devices to your computer wirelessly. like pdas or wireless keyboards.
As far as the diff between one and two gigabytes of memory, obviously more is better, but it really depends on what you intend to do with the laptop. I imagine you probably won't need more than 1. -
Pretty much it goes like this usually:
Internet -> Modem -> computer
but if you want wireless, it has to go:
Internet -> Modem -> Wireless Router -> multiple computer/notebooks
If you take out the wireless router, you can't have access to wireless internet. The Bluetooth is a type of wireless transmissions used in cell phones, PDAs, keyboards, mices, etc.
The ram question is easy, 1gb means 2 ram sticks at 512mb each, 2gb means 2 ram sticks at 1gb each. -
Thank you for all answers. So I don't have to buy the bluetooth if I do not use the wireless keyboard, PDA, or mice, right?
For accessing the internet, if I use the laptop in the university or hotel, I can buy just the wireless card and don't have to buy the wireless router? I can buy the router afterward when I use the laptop at my home, correct?
For the ram, 2GB will run the laptop faster than 1 GB? So, what does the thing like 1.66GHz processor use for? Do they have the same duty? -
Yes, you only need a router if you are at home, but if you are out and about, you can connect to wireless hotspots from hotels, coffee lounges, universities, etc. Just note that it may not be the most secure connection as it is not owned by you. There are also legal issues but thats a whole new topic to lean on.
For RAM, it depends what you do and what your budget is. Of course more is better but if you can't afford it, then at the moment, 1.66 Core 2 Duo and 1gb RAM is sufficient for most users. -
Could I buy just 1.60? 1.66 is much more expensive. What the difference between the two?
-
Not sure if its right, but from what I can recall, 1.6 is Core Duo, while the 1.66 is Core 2 Duo. If I'm mistaken, please correct me.
-
You are right !! Thank you so much !!

You should not get the wireless router, but get the wireless card.
This way, you can bring your laptop to your university and get on their wireless network. At home, you can use your Ethernet cable to connect directly to your cable modem.
As for the two CPU's, the Core 2 Duo will be slightly faster and offer some features---such as 64 bit processing---that the Core Duo does not. Choose it only if the price difference is less than $50 US or if you want to use a 64 bit operating system (such as Vista 64 bit). -
