Audio connectors and video connectors are electrical connectors (or optical connectors) for carrying audio signal and video signal, of either analog or digital format. Analog A/V connectors often use shielded cables to inhibit radio frequency interference (RFI) and noise.

Video connectors carry only video signals. Common video-only connectors include:
Component video aka YPbPr (3 RCA or BNC; or D-Terminal)
Composite video (1 RCA, Antenna socket, or BNC)
DB13W3 ("13W3" computer video connector)
DMS-59, single connector carrying two DVI and two VGA
Musa, British connector used in broadcasting and telecommunications
PAL connector, common in Europe as an antenna connector
S-Video (1 Mini-DIN)
SDI - Broadcast grade digital interface over BNC cables
VGA connector A type of D-sub connector standard on most video cards
Mini-VGA Found on some laptop computers
5 BNC Connectors can also be used to carry the VGA signal as R, G, B, HSync, VSync
Digital Visual Interface (DVI) A hybrid analog/digital connector commonly found on PC graphics cards and LCD monitors
Mini-DVI Found on some Apple laptops
Enhanced Graphics Adapter (EGA)

Audio connectors are electrical connectors designed and used for audio frequencies. They can be analog or digital. Common audio connectors include:
Single-conductor connectors:
Banana connectors
Five-way binding posts and banana plugs for loudspeakers
Fahnestock clips on early breadboard radio receivers.
Multi-conductor connectors:
DB25 is for multi-track recording and other multi-channel audio, analog or digital
DIN connectors and mini-DIN connectors
RCA connectors, also known as phono connectors or phono plugs, used for analog or digital audio or analog video
Speakon connectors by Neutrik for loudspeakers
TRS connector also known as tip-ring-sleeve plug, phone plug, jack plug, mini-jack, and mini-stereo. This includes the original 6.35mm (quarter inch) jack and the more recent 3.5mm (miniature or 1/8 inch) and 2.5mm (subminiature) jacks, both mono and stereo (balanced) versions.
XLR connectors, also known as Cannon plugs, used for analog or digital balanced audio with a balanced line
Digital audio interfaces and interconnects:
ADAT interface (DB25)
AES/EBU interface, normally with XLR connector
S/PDIF, either over electrical coaxial cable (with RCA jacks) or optical fiber (TOSLINK).
