A VGA (Video Graphics Array) cable is a type of connector primarily used to transmit video signals from a computer or other compatible device to a display, such as a monitor or projector. It typically consists of a cable with a 15-pin connector on each end, though there are variations depending on the specific device and its ports. VGA cables are commonly used for connecting desktop computers, laptops, and other devices to monitors, especially older models that may not have newer connection types like HDMI or DisplayPort. However, VGA is becoming less common as newer digital connection standards offer better quality and performance.

The cable you're describing is commonly known as a "3.5mm male-to-male audio cable" or simply an "audio cable." This cable has a 3.5mm plug on both ends, allowing you to connect two audio devices with compatible ports, such as smartphones, laptops, tablets, MP3 players, or speakers. It's often used to transmit audio signals from one device to another, for instance, connecting a smartphone to a car stereo system or speakers, or connecting a computer to external speakers. These cables come in various lengths to suit different needs and are widely available in electronics stores or online retailers.
