Virtual console

A virtual console (VC) – also known as a virtual terminal (VT) – is a conceptual combination of the keyboard and display for a computer user interface. It is a feature of some operating systems such as BSD, Linux, and UnixWare in which the system console of the computer can be used to switch between multiple virtual consoles to access unrelated user interfaces. Virtual consoles date back at least to Xenix in the 1980s.

Usually in Linux (see Linux console), the first six virtual consoles provide a text terminal with a login prompt to a Unix shell. The graphical X Window System starts in the seventh virtual console. In Linux, the user switches between them with the key combination Alt plus a function key – for example Alt+F1 to access the virtual console number 1. Alt+Left arrow changes to the previous virtual console and Alt+Right arrow to the next virtual console. To switch from the X Window System, Ctrl+Alt+function key works. (Note that users can redefine these default key combinations.)

Virtual Console

Virtual Console (バーチャルコンソール, Bācharu Konsōru), sometimes abbreviated as VC, is a specialized section of the Wii Shop Channel and Nintendo eShop online services that allow players to purchase and download games and other software for Nintendo's Wii and Wii U home gaming consoles and the Nintendo 3DS portable gaming console.

The Virtual Console lineup consists of titles originally released on past home and handheld consoles. These titles are run in their original forms through software emulation (excluding GBA titles on 3DS), and can be purchased for between 500 and 1200 Wii Points (Wii), US$2.99 and US$6.99 (3DS) and US$4.99 and US$9.99 (Wii U) depending on system, rarity, and/or demand. Virtual Console's library of past games currently consists of titles originating from the Nintendo Entertainment System, Super Nintendo Entertainment System, Game Boy, Game Boy Color and Nintendo 64, as well as Sega's Master System and Mega Drive/Genesis, NEC's TurboGrafx-16 and SNK's Neo Geo AES. The service for the Wii also includes games for systems that were known only in select regions, such as the Commodore 64 (Europe and North America only) and MSX (Japan only), as well as Virtual Console Arcade, which allows players to download video arcade games. Virtual Console titles have been downloaded over ten million times. The distribution of past games through the Virtual Console is one of Nintendo's attempts at preventing software piracy.

Switch

In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations.

Description

The most familiar form of switch is a manually operated electromechanical device with one or more sets of electrical contacts, which are connected to external circuits. Each set of contacts can be in one of two states: either "closed" meaning the contacts are touching and electricity can flow between them, or "open", meaning the contacts are separated and the switch is nonconducting. The mechanism actuating the transition between these two states (open or closed) can be either a "toggle" (flip switch for continuous "on" or "off") or "momentary" (push-for "on" or push-for "off") type.
