Explanation:
Detailed explanation-1: -The pixel dimensions may be determined by multiplying both the width and the height by the dpi. A digital camera will also have pixel dimensions, expressed as the number of pixels horizontally and vertically that define its resolution (e.g., 2, 048 by 3, 072).
Detailed explanation-2: -The number of pixels across the width and height of the image is called the resolution. An image with 640 pixels across the width and 480 pixels high has a resolution of 640x480. The more pixels in the image file, the higher the resolution.
Detailed explanation-3: -It is usually quoted as width × height, with the units in pixels: for example, 1024 × 768 means the width is 1024 pixels and the height is 768 pixels.
