VGA cables are a type of connection cable used in electronics, specifically in computer systems and laptops. They are designed to transmit video signals from a source device such as a computer to a display device like a monitor or projector. VGA cables have a characteristic 15-pin connector on each end and can support resolutions up to 2048x1536 pixels, making them suitable for high-definition displays. The cables are typically shielded to minimize electromagnetic interference and ensure signal integrity. They are a common choice for connecting legacy devices that do not support newer digital interface standards like HDMI or DisplayPort.
