System

A system is a set of interacting or interdependent component parts forming a complex/intricate whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.

The term system may also refer to a set of rules that governs structure and/or behavior. Alternatively, and usually in the context of complex social systems, the term is used to describe the set of rules that govern structure and/or behavior.

Etymology

The term "system" comes from the Latin word systēma, in turn from Greek σύστημα systēma: "whole compounded of several parts or members, system", literary "composition".

History

According to Marshall McLuhan,

"System" means "something to look at". You must have a very high visual gradient to have systematization. In philosophy, before Descartes, there was no "system". Plato had no "system". Aristotle had no "system".

In the 19th century the French physicist Nicolas Léonard Sadi Carnot, who studied thermodynamics, pioneered the development of the concept of a "system" in the natural sciences. In 1824 he studied the system which he called the working substance (typically a body of water vapor) in steam engines, in regards to the system's ability to do work when heat is applied to it. The working substance could be put in contact with either a boiler, a cold reservoir (a stream of cold water), or a piston (to which the working body could do work by pushing on it). In 1850, the German physicist Rudolf Clausius generalized this picture to include the concept of the surroundings and began to use the term "working body" when referring to the system.

Home automation

Home automation is the use and control of home appliances remotely or automatically. Early home automation began with labour-saving machines like washing machines. Some home automation appliances are stand alone and do not communicate, such as a programmable light switch, while others are part of the internet of things and are networked for remote control and data transfer. Hardware devices can include sensors (like cameras and thermometers), controllers, actuators (to do things), and communication systems. Remote control can range from a simple remote control to a smartphone with Bluetooth, to a computer on the other side of the world connected by internet. Home automation systems are available which consist of a suite of products designed to work together. These typically connected through Wi-Fi or power line communication to a hub which is then accessed with a software application. Popular applications include thermostats, security systems, blinds, lighting, and door locks. Popular suites of products include X10, Z-Wave, and Zigbee all of which are incompatible with each other. Home automation is the domestic application of building automation.

The Legend of Zelda: Ocarina of Time

The Legend of Zelda: Ocarina of Time (Japanese: ゼルダの伝説 時のオカリナ, Hepburn: Zeruda no Densetsu: Toki no Okarina) is a 1998 action-adventure video game developed and published by Nintendo for the Nintendo 64. It was released in Japan and North America in November 1998, and in Europe and Australia in December 1998. Originally developed for the 64DD peripheral, the game was instead released on a 256-megabit (32-megabyte) cartridge, the largest-capacity cartridge Nintendo produced at that time. Ocarina of Time is the fifth game in the The Legend of Zelda series, and the first with 3D graphics. It was followed by the direct sequel, The Legend of Zelda: Majora's Mask, in 2000.

The player controls the series' hero, Link, in the land of Hyrule. Link sets out on a quest to stop Ganondorf, King of the Gerudo tribe, from obtaining the Triforce, a sacred relic that grants the wishes of its holder. He travels through time and navigates various dungeons to awaken the sages, who have the power to seal Ganondorf away forever. Music plays an important role; to progress, the player must learn to play several songs on an ocarina. The game was responsible for increased interest in and rise in sales of the instrument.

Remote control

In consumer electronics, a remote control is a component of an electronic device such as a television set, DVD player, or other home appliance, used to operate the device wirelessly from a short distance. Remote control is a convenience feature for the consumer, and can allow operation of devices that are out of convenient reach for direct operation of controls.

Commonly, remote controls are Consumer IR devices which send digitally-coded pulses of infrared radiation to control functions such as power, volume, tuning, temperature set point, fan speed, or other features. Remote controls for these devices are usually small wireless handheld objects with an array of buttons for adjusting various settings such as television channel, track number, and volume. For many devices, the remote control contains all the function controls while the controlled device itself has only a handful of essential primary controls.

Earlier remote controls in 1973 used ultrasonic tones. The remote control code, and thus the required remote control device, is usually specific to a product line, but there are universal remotes, which emulate the remote control made for most major brand devices.
