Which standard is associated with a 19-pin Type A connector?

The correct answer is associated with the HDMI standard, which features a 19-pin Type A connector. HDMI (High-Definition Multimedia Interface) was designed to transmit uncompressed video and audio data from a source device, such as a computer or a Blu-ray player, to a display, such as a TV or computer monitor. The 19 pins in the Type A connector facilitate this transfer by allowing for high bandwidth and supporting high-definition content, ensuring both video and audio signals can be delivered through a single cable.

In comparison, Thunderbolt uses a different connector design that is designed to support higher data transfer rates and can include video, audio, and data connectivity in one cable, but its connectors are not specifically 19-pin Type A like HDMI. SATA (Serial ATA) is primarily used for connecting storage devices, such as hard drives and SSDs, and utilizes a different connector altogether that typically has 7 pins for data and 15 for power. IDE (Integrated Drive Electronics) is an older interface standard for connecting hard drives, and it utilizes a distinct ribbon cable and connector configuration unrelated to HDMI’s pin design.
