How resolution and colour depth affect file size and image quality?
Changing the image resolution will affect the file size of the image and the quality of the image. Image resolution is measure in DPI, which is Dots Per Inch, this means that if you increase the resolution then the DPI will increase and the quality of the image will get better as a result as there are more pixels that make up the image, so the image will be more distinct and sharper. When the image resolution is increased the image has more pixels, this is the exact opposite to the compression techniques, this means that the file will get a lot bigger as the number of pixels increases. Decreasing the resolution, however, will make the image quality lower but will reduce the file size.
What is meant by pixel resolution and how does this affect the resolution of the image?

What does resolution means in Photoshop?
That means 72 pixels are distributed vertically and horizontally in each inch (each inch of photo contains 72x72 pixels). This is explanation for photo which have Image > Image Size > Resolution > 72 pix/inch. This resolution is suitable for Web output, for print you will need at least 150-300px/inch.
What is resolution in computer graphics?
The resolution of an image in computer graphics refers to the pixel density of said image. For instance, older monitors used 800x600 often times. This means that for every 4 pixels in the horizontal direction, there are 3 in the vertical. This is where the aspect ratio comes from, which for an 800x600 resolution, is 4:3. The higher the value of the resolution, the more pixels there are per area of the image or screen, which means that there is more potential for fine detail, and on most systems means a crisper image.

Does a higher pixel screen mean better resolution?
not really, but it gives you the proportion of, indeed, how many pixels the screen fits in any given square inch.for example if you have two 20" screens, and one has 2,000 pixels per square inch and the other one 7,000 it means that the second one has a higher resolution. this also means that the pixels are a lot smaller.the formula to calculate it is (X2+Y2)/Z2 Where X and Y are the resolution numbers (in whatever position) and Z is the size in inches.
What caluclate means in maths?
