Need to understand.Does memory card I buy have to be compatible to amount of pixels on computer? What is best size? Well, you're kind of comparing apples and oranges... First the easy answer -- memory cards do not have to be compatible with anything except the device they are used in. Buy whatever your camera can read/write to.
A pixel is a display element. Think of your computer screen as made up of thousands of tiny squares. Each square is one color. The more squares you have, the smaller they are and the more detail you can get in the picture on your screen. The reason this matters in cameras is that the more megapixels your camera can use, the more detail it can include in your picture. The effect on memory is that the more megapixels (and the higher the quality you set on the camera), the fewer pictures you can fit on a memory card. So the more memory you buy, the more pictures you can take before you have to download to your computer and clear the card. Buy the biggest you can afford (memory costs go up by size...)
