What is meant by resolution when using bitmap images?

Resolution in the context of bitmap images refers to the amount of detail an image holds, typically measured in pixels per inch (PPI) or dots per inch (DPI). Higher resolution indicates more pixels in a given area, resulting in greater detail and clarity in the image. Conversely, low resolution can lead to pixelation and loss of quality when the image is enlarged. Essentially, resolution directly impacts the sharpness and overall visual quality of the bitmap image.
