Q:

Using a smartphone as a wireless router

I wanted to know if it is possible for a smartphone with hotspot capabilities (such as some Android devices) to act as a Wi-Fi router. 
Basically, the setup would be something like :
                 Internet
                    |
                Smartphone 
              /     |      \
Wireless Drive   Computer   Wireless Printer

The idea behind this is to be able to access the Printer, the Drive, and Internet with the Computer only being connected to the Smartphone via Wi-Fi. 
I have no good knowledge about networks, so pardon me if my question sounds stupid. 
Thanks

You have lots of articles that covers this topic.  
WiFi Tethering essentially turns your smartphone into a wireless router.  When your phone has a data connection, it can share that connection with all of the other devices connected to it.  When it doesn’t have a data connection, it still functions as a wireless router – or more accurately, as a switch. 
Since you didnt specify smartphone that you want to use, I will list you some articels you should consider

Use Android as router
Google App WiFi Tether Router - paid
Google App Portable Wi-Fi Router - free
