Where is the video card located and how does it send information to the monitor?

Oh, dude, the video card is usually located in the motherboard of your computer, like a little tech ninja hiding in plain sight. It sends information to the monitor through a cable called HDMI, DisplayPort, or VGA, depending on how old school you wanna go. It's basically like the middleman between your computer and the monitor, making sure you get to see all those cat videos in high definition.
