Hi all. Complete newbie to properly setting up tv to get the most. Have a Samsung LN40C500F3F and first question is: is this considered a smart tv?

Secondly if so I'm trying to connect it to home network. Looks like I will need to connect a USB as my on screen options for software upgrade immediately scans for USB. I can't find on google (I know right?!) what would be compatible to achieve this. All links take me to Samsung page but no info that assists.

I didn't find the right solution from the Internet.
