Home computerHome computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single, non-technical user.
Random-access memoryRandom-access memory (RAM; ) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code.
Video-signal generatorA video signal generator is a type of signal generator which outputs predetermined video and/or television waveforms, and other signals used in the synchronization of television devices and to stimulate faults in, or aid in parametric measurements of, television and video systems. There are several different types of video signal generators in widespread use.
Composite videoComposite video, also known as CVBS (composite video baseband signal or color, video, blanking and sync), is an analog video format that combines image information—such as brightness (luminance), color (chrominance), and synchronization, into a single signal transmitted over one channel. It is most commonly used for standard-definition television, and is sometimes referred to as SD video.
Integrated circuitElectronic circuit formed on a small, flat piece of semiconductor materialA microscope image of an integrated circuit die used to control LCDs. The pinouts are the dark circles surrounding the integrated circuit.An integrated circuit (IC), also known as a microchip or simply chip, is a compact assembly of electronic circuits formed from various electronic components, such as transistors, resistors, and capacitors, and their interconnections.
PixelIn digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element of a raster image. In a display device, dot matrix printer, or ASCII art a pixel is the smallest element whose output can generally be controlled independently. The concept of a picture element dates to the earliest days of electronic imaging.
BitmapIn computing, a bitmap (also called raster) graphic is an image formed from rows of different colored pixels. A GIF is an example of a graphics image file that uses a bitmap. As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: the pix-map, which refers to a map of pixels, where each pixel may store more than two colors, thus using more than one bit per pixel.
Audio signalAn audio signal is a representation of sound, typically using either a changing level of electrical voltage for analog signals or a series of binary numbers for digital signals. Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz, which corresponds to the lower and upper limits of human hearing.VideoVideo is an electronic medium used for the recording, copying, playback, transmission, and display of moving visual images and pictures, with or without accompanying audio. Video technology was initially developed for live transmission and later expanded to include recording and storage through analog formats such as magnetic tape.Component videoComponent video is an analog video signal split into two or more component channels. In popular use, it refers to a type of component analog video (CAV) information that is transmitted or stored as three separate signals. Component video can be contrasted with composite video in which all the video information is combined into a single signal that is used in analog television. Like composite, component cables do not carry audio and are often paired with audio cables.
Video game consoleComputer system for running video gamesA collection of various classic video game consoles at a game show in 2010A video game console is an electronic device that outputs a video signal or image to display a video game that can typically be played with a game controller.
Arcade gameAn arcade game, or coin-op game, is a coin-operated entertainment machine typically installed in public businesses such as restaurants, bars and amusement arcades. Most arcade games are presented as primarily games of skill and include arcade video games, pinball machines, electro-mechanical games, redemption games or merchandisers.*As an Amazon Associate I earn from qualifying purchases.
