The term VGA (Video Graphics Array or Video Graphics Adapter) is a graphics display system for PCs developed by IBM. VGA has become one of the standards for the PC image. In text mode, VGA provides a resolution of 720 by 400 pixels. In graphics mode, the resolution is either 640 by 480 (with 16 colors) or 320 by 200 (with 256 colors). The color palette is 262,144.Unlike earlier graphic standards for PCs - MDA, CGA, EGA and VGA - uses analog signals rather than digital signals. Since its introduction in 1987, several other standards have been developed that offer greater resolution and more colors (SVGA, XGA ...), but VGA remains the denominator used. All personal computers manufactured today still have support VGA, and possibly some other more advanced connection.

NTSC and PAL are the two coding systems for television signals, each other, they are totally incompatible. NTSC is mainly used in the United States, while the PAL system is one that is typically used in Europe. PAL: 720 x 576 pixels and 25 frames per second NTSC: 720 x 480 pixels and 29.9 frames per second.

The mini-DIN connector designates a family of circular connectors, each with a diameter of 9.5 mm and a varied number of pins inside. Although initially designed as mere electrical connectors, they are very popular in electronics and computers, having succeeded the larger DIN connector. Both are standards of Deutsches Institut für Normung, the German standardization body.

CVBS is the acronym by which composite video is often referred to. The idea of this definition means Color, Video, Erase and Synchronized.

The most widely used cable is the already known coaxial cables with a BNC connector or RCA connector.

The RCA (Radio Corporation of America) connector is a connector used to send video signals or audio.
This is a circular two-contact connector; signal and ground, used with coaxial cables. Each signal uses a single cable and to differentiate color coded RCA connector on the set.
