DVI :

Digital Visual Interface (DVI) is a video display interface. The digital interface is used to connect a video source to a display device, such as a computer monitor It was developed with the intention to transfer digital video content.

composite video: 
Composite video (1 channel) is an analog video transmission (with no audio) that carries standard definition video typically at 480i or 576i resolution. Video information is encoded on one channel in contrast with slightly higher quality S-video (2 channel), and even higher quality component video (3 or more channels).

S- video:

S-video commonly known as Separate Video, and super video is a signalling standard for standard definition video, typically 480i or 576i. By separating the black-and-white and colouring signals, it achieves better image quality than composite video but has lower colour resolution than component video.

HDMI:

HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device to a compatible computer monitor, digital television or video projector. 

RCA connector: RCA cables are used to carry video and audio signals, they are primarily used for stereo equipment and often consumer grade. RCA is still often used by many devices before and after the digital switchover (VHS, DVD players and TV's)
