Internet on acer aspire 5310 laptop with Linux OS?

Hi all,
I’m using acer laptop [acer aspire 5130 + Fedora 7 ]
i want to know does any(airtel,bsnl,tata)
data card supports linux OS?
Which is simple and best one to use?

How do I check my computers specs on Linux?

I’ve recently made the switch from Microsoft Windows to Linux. The distribution I’m using is Fedora 7.

What I would like to know, is how do I check my systems specs? For example, on Windows you right click on My Computer and go Properties. You then get an overview or you can choose to go to the Device Manager.

Basically I’m trying to keep an eye on all my hardware to ensure its running correctly.

Thanks.
