Which internet addition do I rrly need?

[Ahura]

Well, Im still looking around for a laptop. However, looking through all the internet add-on and wat/not, I got lost as to what are they and their differences.

The internet that I'll be most likely to depend on wholly will be school's one. Not sure which type, if there is one, that is.

From what I'vek nown so far:
After 802.11g is 802.11n, which has better connection in term of cover or something like that. Do I rrly need this? would it better if I cover this anyway for future proof?

Then choosing a Mobile Broadband add-on, like how are they different to the regular 802.11? Im not quite sure what distinguished MB from the "regular".

And then wi-fi.
I know that coffee shop advertised really hard of their hotspot and all, but again how is wi-fi different from the two above.

Please explain cause Im like lost as to which is best at wat.

Thanks

Most if not all laptops come with Ethernet, and wireless cards.
802.11 is all wireless protocols, the letter following the protocol is the standard it will be either a, b, g, or n. With the 'n' standard being the newest, and not fully accepted as of yet but it will be in the future. The most common standard is 'g', and you will run across the 'b' standard also. I would look for a laptop that handles the 'g' and 'n' standards. The 'n' protocol produces more output.

Mobile broadband is what is offered by cell phone companies, I'm not familiar with this, however a guy at work connects his laptop to the internet through his cellphone using a USB adapter, I don't know what kind of throughput he gets. I we don't have any 3G networks up in this area.

Here are some wikipedia pages on wireless protocols: http://en.wikipedia.org/wiki/802.11

I sort of get the 802.11 already. So then the n is just new.


Then regarding Mobile Broadband, would say that is something I should even try and cover? (future proof)
And wwhat about wif-fi?

wi-fi is the 802.11.

The mobile broadband is something you subscribe to from celluar phone companies like Verizon, ATT, Sprint. The device itself can be inside the laptop (an option you have to choose when purchasing) or the most common way is the USB modem, which simply plugs into a USB port. The benefit of this service is that you can get internet anywhere the cell signal works. The cost is usually around $60 a month for the service.
