Final answer:
The common component found on ultra thin laptops and tablet devices is the touch screen interface.
Step-by-step explanation:
The common component found on ultra thin laptops and tablet devices is the touch screen interface. This feature allows users to interact with the device by tapping, swiping, and pinching on the screen, making it easier to navigate and use the device without the need for a physical keyboard or mouse.
While solid state drives (SSDs) are also commonly found in ultra thin laptops and tablets, they are not exclusive to these devices and can be found in other types of computers as well. Upgradeable RAM and field serviceable parts, on the other hand, are less common in ultra thin laptops and tablets since these devices prioritize compactness and portability over expandability and repairability.
