<span>Install a video card into a slot on the motherboard
Since you're wanting to install a new video card in your computer, let's look at the provided options and see what makes sense.
Install a video card into a socket on the motherboard
* Most motherboards have sockets that you can use to replace the processor or increase the amount of RAM they have. So plugging a video card into a socket doesn't make sense in this context.
Install a video card into a slot on the motherboard
* Most motherboards have expansion slots that you can plug in new devices and cards such as video cards, audio cards, etc. This makes sense in the context of you adding a new video card to your computer and is the correct choice.
Install a video card into a port on the motherboard
* Ports are generally used to attach external devices for the computer to communicate with. Some examples would be serial ports, or USB ports. The video card you're adding will likely have some video ports such as HDMI, DVI, or other types to connect to the monitor, but as mentioned, ports are generally used to communicate with devices EXTERNAL to the computer. So this is a bad choice.
Install a video card into a chipset on the motherboard
* The chipset on a motherboard is the set of support chips to provide the processor with access to the bus controlling data traffic on the motherboard between expansion slots, I/O devices, RAM, etc. Motherboards are generally designed around a chipset and you can not replace the chipset to upgrade the motherboard. So this is the wrong answer.</span>
