Ok so i'm lloking to by this LG Blu-ray player with built in wifi BP335W and I have some questions because I have no Idea how they work. I have a 32' Emerson LED Flatscreen TV

1.) How do they work?
2.) What do they do? What can you do with them?
3.) Do you need to have internet to use the wifi?
4.) Will it work with my tv?
5.) Can you browse the internet on your tv with it?
6.) Can you connect a laptop to it and use the wifi
7.)Is the BP335W a good model?

I know a lot of question but i'm 15 and not very tech savy when it comes to Blu-ray players
Thanks!
