-In digital imaging, a pixel (or picture element) is a single point in a raster image. The pixel is the smallest addressable screen element, it is the smallest unit of picture which can be controlled. Each pixel has its own address
What is aliasing?
-Distortion caused by a low sampling rate, as Moire effect or stair-stepped edges
What is antialiasing?
- technique that is used to smooth jagged distortions in curves and diagonal lines so they appear smoother
What is Raster, Bitmap graphics?
-the rectangular formation of parallel scanning lines that guide the electron beam on a television screen or a computer monitor
What is Vector?
-Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based on mathematical equations, to represent images in computer graphics.

What is Screen Resolution?
-Resolution measured in pixels per inch (PPI). It helps to think of the image as a grid. As the resolution increases, the size of the grid cells get smaller, in effect increasing the number of cells (pixels) per inch.

What is Image Resolution?
-Image resolution describes the detail an image holds. The term applies to digital images, film images, and other types of images. Higher resolution means more image detail.

What is the common Image Resolution used for Web Graphics?
-24 bit
-24 bit
What is the difference between Screen and Image Resolution?
-screen resolution as the resolution increases the size of the grid gets smaller, image resolution basically zooms in
-screen resolution as the resolution increases the size of the grid gets smaller, image resolution basically zooms in
What is Bit Depth?
-Color depth or bit depth, is a computer graphics term describing the number of bits used to represent the color of a single pixel in a bitmapped image or video frame buffer. This concept is also known as bits per pixel
