DPI Full Form Explained

The full form of DPI in the context of digital images is Dots Per Inch.

DPI is a measure of spatial printing or dot density. It indicates how many individual dots of ink or toner a printer places within an area of one linear inch.

Higher DPI values mean that more dots are printed in the same space, resulting in finer detail and higher quality for printed images. While DPI is primarily a print resolution term, it's often related to the pixel density (PPI - Pixels Per Inch) of digital images displayed on screens.
