One of the biggest risks of using the clipboard is "overwriting" your data. If you copy a screenshot and then copy a line of text before pasting the image, the image is gone—unless you use .
This is the first critical divergence: Unlike a camera taking a photo of a monitor, the OS has direct access to the final rendered pixels of every window, including their z-ordering, transparency, and hardware-accelerated effects. clipboard screenshot

Tapping the key usually captures your entire desktop and saves it to the clipboard.
Why do we use clipboard screenshots rather than saving files? Because . It turns a spatial-visual event (what I see) into a temporal-interactional object (what I can paste now ). This aligns with the HCI principle of external cognition : offloading short-term memory to the environment. Windows 11 and macOS now support HDR screenshots
