NOTE: Unlike monitor resolution, the resolution of a printer or scanner is analogous to pixel density rather than total pixels. Printer and scanner resolution is measured in dots per inch, or DPI.

An optical resolution describes a photograph with no digital enhancements, and best describes the resolution of the camera. An enhanced resolution describes any photograph that's digitally enhanced or adjusted, e.
A resolution is a term used to describe a set of steps or procedures that correct an issue with a product. For example, when encountering a problem with a computer , you may first troubleshoot the problem and find a fix on Computer Hope , following the steps is the resolution.

Now, compare that to an image with 72ppi, which has a lot fewer pixels per inch. As you've probably guessed, it won't look nearly as sharp as the ppi image. It's better to have more information than not enough! It's much easier for image editing applications, like Photoshop, to discard any unwanted image information reducing the size of an image than it is to create new pixel information enlarge an image.
Some professional, high-end printers may require images to be up to ppi for printing. Non-professional printers such as inkjet, laser, and other common printers can best print images that are at least to ppi and higher. For images that just need to "look good", ppi will work.
Photographic prints are recommended to be at least ppi. Images for large format poster printing can be around ppi depending on how close the image will be viewed. Screen images are different than images for printing because we must think about the pixel dimensions of monitors, TVs, projectors, or display, rather than PPI. Use PPI for printed images, but use pixel dimensions of the image are what really determine the size of the image and quality of how it will display on the web or devices.
The idea has been for many years that images should be saved with a resolution of 72 PPI. Each monitor is different and has a different resolution, so it makes it difficult to design a website that contains images that will display perfectly on every type of display. Over the years, technology has improved and so has the quality of our displays.
Most popular are Apple's new retina displays that are on the most recent Macbooks, iPhones, and iPads. If you're a web developer, check out some ways people are designing for retina or high pixel density displays. Just like web images, images for projectors should match the pixel dimensions of the projector.
