Which device is NOT likely to be connected via a PATA/SATA connection?

The graphics card is not likely to be connected via a PATA/SATA connection because it typically connects to the motherboard through a PCI Express (PCIe) slot. PATA (Parallel Advanced Technology Attachment) and SATA (Serial Advanced Technology Attachment) are standards primarily used for storage devices such as hard drives, optical drives, and solid-state drives. These connections are specifically designed to transfer data between storage devices and the computer system's motherboard.

Hard drives, optical drives, and solid-state drives all use PATA or SATA interfaces for data transfer, as they are meant to store data and rely on these protocols for communication with the system. By contrast, the unique functionality and architecture of graphics cards necessitate a different type of connection that allows for the high bandwidth required for processing graphics and rendering images effectively. This distinction highlights why the graphics card does not use PATA or SATA connections.
