By placing an image in layout, sometimes you need to resize it to fit in a specific space that is called effective PPI. If you want to resize the image in the layout, the effective PPI changes but the actual pixel dimension remain the same for the image file.

Knowing about these terms is necessary when you work on print projects for keeping the quality of the image. Usually, it is suggested that start your project with high resolution image (high actual PPI) for having a good print quality, and then resizing it within the layout without changing the resolution too much (maintain effective PPI that is reasonable).
