Linux is a family of free and open-source software operating systems built around the Linux kernel.

Typically, Linux is packaged in a form known as a Linux distribution (or distro for short) for both desktop and server use.

The defining component of a Linux distribution is the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds.

Many Linux distributions use the word "Linux" in their name.

The Free Software Foundation uses the name GNU/Linux to refer to the operating system family, as well as specific distributions, to emphasize that most Linux distributions are not just the Linux kernel, and that they have in common not only the kernel, but also numerous utilities and libraries, a large proportion of which are from the GNU project.

This has led to some controversy.

Android TV is a version of the Android operating system designed for digital media players.

A replacement for Google TV, it features a user interface designed around content discovery and voice search, surfacing content aggregated from various media apps and services, and integration with other recent Google technologies such as Assistant, Cast, and Knowledge Graph.

A virtual private network (VPN) extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.

Applications running across a VPN may therefore benefit from the functionality, security, and management of the private network.

Amazon Fire TV is a digital media player and its microconsole remote developed by Amazon.

The player is a small network appliance entertainment device that streams digital audio/video content to a high-definition television from the home (internet) network.

The player also allows users to play video games with the included remote, via a mobile app, or with an optional game controller.

A router is a networking device that forwards data packets between computer networks.

Routers perform the traffic directing functions on the Internet.

Data sent through the internet, such as a web page or email, is in the form of data packets.

A packet is typically forwarded from one router to another router through the networks that constitute an internetwork until it reaches its destination node.
