Can someone answer how does the screenshot works? irrespective of mobile phone or PC? I've tried to look for the answer all over the internet but every where i can find only the videos how to take screenshot? But none of them gives me the result. Does that relates to software which buffers and converts the screen-content to image?
Irrespective of hardware or software in computers or smartphones, there is something called a "frame buffer" that stores all of the pixels currently displayed on the screen as numbers. A screenshot is essentially a dump of all of those numbers into a file, with more numbers tacked on the front to cause a computer to interpret them as a particular type of image.
