There is a small difference between a smart TV and a normal TV.A smart TV allows you to access the internet through its internet accessibility feature, while a normal TV does not have the option of surfing the internet.
A Smart TV makes it possible to stream movies and shows using the internet, an option that isn’t available in normal televisions. The TV is ideal for people who like streaming videos through YouTube and Netflix.While this is the case,your house must have Wi-Fi for you to be able to stream videos.
While smart televisions have the additional feature, they are priced a bit expensive than the normal televisions.You can see Smart TV prices through this link (Smart TV link)
If you don’t like streaming videos, there is no need of buying a smart television but if you are fond of downloading videos and movies, go for a smart TV.
