Notebook and Laptop are same.
Netbook are very small usually under 11″ screen and relatively under powered. Keyboards are usually only around 70% of the full size so difficult to type proficiently.
Notebook/Laptops from 13″ screen to and up are good for anything you would normally do on desktop.
Netbook on the other hand are only good for quick small document updates, web surfing and note taking due to long battery life.
