The Nintendo Switch is the seventh major video game console developed by Nintendo. Known in development by its codename NX, it was unveiled in October 2016 and was released worldwide on March 3, 2017. Nintendo considers the Switch a "hybrid" console: it is designed primarily as a home console, with the main unit inserted onto a docking station to connect to a television. Alternatively, it can be removed from the dock and used similarly to a tablet computer through its LCD touchscreen, or placed in a standalone tabletop mode visible to several players.
The PlayStation 4 (PS4) is an eighth-generation home video game console developed by Sony Interactive Entertainment. Announced as the successor to the PlayStation 3 during a press conference on February 20, 2013, it was launched on November 15 in North America, November 29 in Europe, South America and Australia; and February 22, 2014, in Japan. It competes with Nintendo's Wii U and Switch, and Microsoft's Xbox One.
In computer programming, an application programming interface (API) is a set of subroutine definitions, communication protocols, and tools for building software. In general terms, it is a set of clearly defined methods of communication between various components. A good API makes it easier to develop a computer program by providing all the building blocks, which are then put together by the programmer. An API may be for a web-based system, operating system, database system, computer hardware, or software library. An API specification can take many forms, but often includes specifications for routines, data structures, object classes, variables, or remote calls. POSIX, Windows API and ASPI are examples of different forms of APIs. Documentation for the API is usually provided to facilitate usage and implementation.
Xbox One is a line of eighth generation home video game consoles developed by Microsoft. Announced in May 2013, it is the successor to Xbox 360 and the third console in the Xbox family. It was first released in North America, parts of Europe, Australia, and South America in November 2013, and in Japan, China, and other European countries in September 2014. It is the first Xbox game console to be released in China, specifically in the Shanghai Free-Trade Zone. Microsoft marketed the device as an "all-in-one entertainment system". The Xbox One line mainly competes against consoles such as Sony's PlayStation 4 and Nintendo's Wii U and Switch.

A capacitor is a passive two-terminal electrical component that stores potential energy in an electric field. The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. The capacitor was originally known as a condenser or condensator. The original name is still widely used in many languages, but not in English.
A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode that emits light when activated. When a suitable current is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light is determined by the energy band gap of the semiconductor. LEDs are typically small and integrated optical components may be used to shape the radiation pattern.
