Hello,

Five students in our dormitory jointly acquired a 2 Mbps DSL connection.

We have attached a Wi-Fi router with this connection, and all five are using laptops connected with this Wi-Fi, in our separate rooms.

The two mobile communication systems (GSM system and CDMA system) are generally used. But I don’t know which is better between them? Please explain about GSM and CDMA and tell me which one I shall choose.

guys, I would like to ask something  about file sharing.

How can I make a shared folder in a network in which only a specific user can access my file? In short, there are different users that will access my shared file but they have different files to be accessed. How can I restrict my other shared files to those unauthorized users?

I have 3 computers in my office.

One on the 1st floor and another two on the 2nd floor. Also we have 3 laptops used by my employees. How can I set up Internet WiFi network between these computers? Do I have to buy any hardware for it or can I just use a wireless LAN card? And I want no interruption while I use the network.
