[ Laptops & Notebooks ] Open Question : Does watching movies online download things onto my laptop ...?

Okay, So I watch A lot of TV Shows online (Because the TV shows I like are never on my TV). I've also watched a few films online. I've used novamov, megavideo, putlocker, loombo etc. However my Mom got our internet bill and it said that I've downloaded too much MB and GB etc. I told my Mom I watch those movies off iTunes because she doesn't trust any other site. So I told her I won't watch any other movies online. Does watching these things, download things onto my computer? My laptop is working fine so I don't have a virus. Is it the Films and TV Shows they are talking about when they say I've used too much downloading time ec. PLEASE HELP!
