What does dots per inch (DPI) measure?

Correct option is B

The correct answer is (b) Density of pixels on a computer screen

Explanation:

• DPI (Dots Per Inch) is a measure of spatial printing, video, or image scanner dot density.
• Specifically, it describes the number of individual dots that can be placed in a line within the span of 1 inch.
• On a computer screen, it is often used interchangeably with PPI (Pixels Per Inch) to describe the resolution and clarity of the display.
• Higher DPI means higher resolution, resulting in more detail and sharpness in the image.
• In printing, it refers to the number of ink dots a printer puts on a paper per inch.

• Standard web images are typically 72 or 96 DPI, while high-quality printing usually requires 300 DPI or more.
• DPI is a key factor in determining the quality of digital-to-physical reproduction.
