Calling that shield a shell (or D-shell) can be ambiguous, as the term shell is also short for the cable shell, or backshell. D-sub connectors have gender: parts with pin contacts are called male connectors or plugs, while those with socket contacts are called female connectors or sockets. The socket's shield fits tightly inside the plug's shield.
It was the traditional connector for joystick input, and occasionally MIDI devices, until made obsolete by USB in the late 1990s. Originally located on a dedicated Game Control Adapter expansion card, the game port was later integrated with PC sound cards, and still later on the PC's motherboard. During the transition to USB, many input devices ...
F connectors, also known as RF connectors, were the standard analog connector of the analog era in the Americas, used primarily with coaxial cable (RG-59 and RG-6), and have been repurposed for generic digital data connections. SCART was the standard connector of the analog era in Europe. S-Video was an improvement over the F connector.
A sound card (also known as an audio card) is an internal expansion card that provides input and output of audio signals to and from a computer under the control of computer programs. The term sound card is also applied to external audio interfaces used for professional audio applications.
Three RCA connectors - yellow for composite video, and white and red for stereo audio RCA connector: Widely used in consumer electronics for audio and video. A single connector must be used for each signal. SCART: Consumer electronics, mostly in Europe. Carries analog stereo sound, along with composite video and/or RGB video.
The Video Graphics Array (VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, [1] as well as many monitors, projectors and HD television sets.
Early systems such as Digidesign's Sound Tools (1989) and Session 8 (1993) [3] and the Ensoniq PARIS (1998) consisted of an external unit that connected to the host computer with a ISA or SCSI card, but from the late 1990s onwards it became practical to use standard computer interfaces such as FireWire, USB, and eventually Thunderbolt instead.
Digital audio is now common and may be transmitted via USB sound cards, USB headphones, Bluetooth, display connectors with integrated sound (e.g. DisplayPort and HDMI). Digital devices may also have internal speakers and mics. Thus the phone connector is sometimes considered redundant and a waste of space, particularly on thinner mobile devices.
