A video game is an electronic game that involves human interaction with a user interface to generate visual feedback on a video device. The word video in video game traditionally referred to a raster display device, but it now implies any type of display device that can produce two or three dimensional images. The electronic systems used to play video games are known as platforms; examples of these are personal computers and video game consoles. These platforms range from large mainframe computers to small handheld devices. Specialized video games such as arcade games, while previously common, have gradually declined in use. Video games have gone on to become an art form and industry.
The input device primarily used to manipulate video games is called a game controller, and varies across platforms. For example, a controller might consist of only a button and a joystick, while another may feature a dozen buttons and one or more joysticks. Early personal computer games often needed a keyboard for gameplay, or more commonly, required the user to buy a separate joystick with at least one button. Many modern computer games allow or require the player to use a keyboard and a mouse simultaneously. A few of the most common game controllers are gamepads, mouses, keyboards, and joysticks.
Computer hardware is the collection of physical elements that constitutes a computer system. Computer hardware refers to the physical parts or components of a computer such as monitor, keyboard, computer data storage, hard drive disk, mouse, system unit (graphic cards, sound cards, memory, motherboard and chips), etc. all of which are physical objects that can be touched. In contrast, software is untouchable. Software exists as ideas, application, concepts, and symbols, but it has no physical substance. A combination of hardware and software forms a usable computing system.
A game controller is a device used with games or entertainment systems to provide input to a video game, typically to control an object or character in the game. A controller is usually connected to a game console or computer by means of a wire or cord, although wireless controllers are also widespread. Input devices that have been classified as game controllers include keyboards, mice, game pads, joysticks, etc. Special purpose devices, such as steering wheels for driving games and light guns for shooting games, are also game controllers.
Game controllers have been designed and improved over the years to be as user friendly as possible. This has led to a wide range of styles and button layouts, with some controllers being better at certain types of games. For example, the Nintendo GameCube controller has a reputation for being uncomfortable for fighting games due to its button layout, which discourages repeated presses of the same button, whereas the Microsoft Xbox controller, with its shoulder triggers that mimic actual triggers such as those found on guns, has become popular for shooting games. Some controllers are designed to be deliberately best for one type of game, such as steering wheels for driving games, or dance pads for dancing games.
BNC 575 is electronic test equipment, which is the 2007/2008 version of a series of benchtop digital delay generator/pulse generator that began with the BNC 400 and BNC 500 in 2000. This version improves upon the earlier designs with better resolution (250ps), more channels (up to 8, each with separate delay and widths) and more functionality (summed channels, more output and input options, more allowable communication protocols.) Channel-to-channel and external trigger jitter have both been significantly improved from earlier designs. The BNC 575 replaces the BNC 565 and BNC 555. New capabilities include int/ext clock for synchronizing and pulse picking, summing timing of several channels onto one, independent trigger and gate and selectable timing reference for each channel.
The BNC 575 features a single timing board that is coupled to modular input boards and modular output boards. In this way the BNC 575 can be configured to have a number of different electrical and optical inputs and outputs. This designs also allows for customization of the unit. For example, optical outputs were developed to deliver timing pulses in a harsh electrical environment. The Gate input can be converted to a second Trigger input, and one can select which channel operates with which of the two triggers.
Electronic test equipment (sometimes called "testgear" or "bench top") is used to create signals and capture responses from electronic Devices Under Test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced and repaired. Use of electronic test equipment is essential to any serious work on electronics systems.
Practical electronics engineering and assembly requires the use of many different kinds of electronic test equipment ranging from the very simple and inexpensive (such as a test light consisting of just a light bulb and a test lead) to extremely complex and sophisticated such as Automatic Test Equipment. ATE often includes many of these instruments in real and simulated forms.
On personal computers, the turbo button is a button which changes the effective speed of the system, making equipment run faster (or slower) in some way.
The name is based on that of a forced induction air compressor which makes a car go faster (a turbocharger).
