Smart TVs work by using special computer processors and memory to help the TV juggle video processing, upscaling, Internet connection and music and video buffering. By definition, a smart TV is any television that can connect to the Internet to access streaming media devices and that runs entertainment applications.
Smart TVs use either a direct, wired Ethernet connection or a wi-fi connection that is built into a home network to access the Internet. Most newer models of smart TVs have wi-fi built into them so that they don’t need an Ethernet connection.
Smart TVs do not have a standard operating system or interface. The type of software and applications offered vary greatly from one smart TV to another, and typically get more advanced with higher-end models. The arrangement of the applications also varies, as some TVs use a scrolling screen of icons, and others use tabbed windows and scroll bars along the bottom of the screen.
Due to the need for an Internet connection, smart TVs can freeze and crash, just like phones and computers. The new technology and software involved sometimes cause videos or applications to freeze. Typically, though, turning the TV off and restarting the Internet connection fixes these issues.
