A:AnswerThe television function works off of being plugged in to your satellite or cable connection. No internet necessary. However, to use the smart tv functions, you need to be connected to the internet either by wires or wirelessly.
A:AnswerNo microphone on the TV but I use a Chromecast and either my phone or a Google home device to play content. My understanding is that you could voice control it with a Fire cube however and I do that with another unit in my house since the Fire cube has an IR transmitter like a remote control does.
A:AnswerYes, YouTube is able to be downloaded to this computer very easily. As well as other applications including but not limited to Hulu, Netflix and YouTube as well as many others.
