What does Vector and Bitmap mean?
Vector and bitmap are both image files. Bitmapped images are images that are stored on a pixel by pixel basis and because of this, when you enlarge the image it can appear blocky. A vector image is constructed from dots, lines, shapes, etc. Each part has a particular position within the image with it's own dimensions. Because vector images are constructed using images, they can be enlarged without loss of image quality. Vector images do not get the blocky appearance of an enlarged bitmap image.

How is a bitmap graphic defined?
Excerpts from Microsoft Computer Dictionary (5th Edn): bitmap n. A data structure in memory that represents information in the form of a collection of individual bits. A bit map is used to represent a bit image. Another use of a bit map in some systems is the representation of the blocks of storage on a disk, indicating whether each block is free (0) or in use (1). bitmapped graphics n. Computer graphics represented as arrays of bits in memory that represent the attributes of the individual pixels in an image (one bit per pixel in a black-and-white display, multiple bits per pixel in a color or gray-scale display). Bitmapped graphics are typical of paint programs, which treat images as collections of dots rather than as shapes. See also bit map.
Do vector based images usually require less memory than bitmap images?

How many bits per pixel are needed to represent a black and white image?
A "black and white" image is generally actually a grayscale image, which is typically represented with 8 bits per pixel. However, you can make images that use only one bit per pixel, making each pixel either fully black or fully white. The images created by the early graphics software MacPaint used only one bit per pixel.

What are the advantages and disadvantages of a raster image?
Raster images are the natural choice when representing images like photos. They store a value for each pixel, compressing the images with various schemes. This way the images are large when compared to vector images, but contain all required detail. If the image is a rendered one or made just fo geometric shapes, then vector images are better due to their small size.

How are bitmap images stored on a computer system?
Bitmap images, also called raster images -- are a collection of colored squares/dots on a grid each chunk of this grid and each one is called a pixel -- and the amount of pixels is the resolution of the image. Each pixel may have one of 1,658,135 different color values (255 channels red, 255 green, 255 blue). In the bitmap file format (.bmp) each pixel has its information saved individually with no chunking, shortcuts or other methods applied to it to reduce its filesize. Modern raster formats (e.g. JPG, GIF, PNG) are essentially bitmap images that have compression applied to it in order to reduce filesize and sometimes implement extra features like transparency (also known as alpha). The concept of image compression is a beyond the scope of this question.

What is depth buffer method?
The Z-buffer algorithm is a convenient algorithm for rendering images properly according to depth. To begin with, a buffer containing the closest depth at each pixel location is created parallel to the image buffer. Each location in this depth buffer is initialized to negative infinity. Now, the zIntersect and dzPerScanline fields are added to each edge record in the polyfill algorithm. For each point that is to be rendered, the depth of the point against the depth of the point at the desired pixel location. If the point depth is greater than the depth at the current pixel, the pixel is colored with the new color and the depth buffer is updated. Otherwise, the point is not rendered because it is behind another object.

What is image file formatting?
It is a standardized means of organizing and storing digital images. Image files are composed of either pixels, vector (geometric) data, or a combination of the two. Whatever the format, the files are rasterized to pixels when displayed on most graphic displays. The pixels that constitute an image are ordered as a grid (columns and rows); each pixel consists of numbers representing magnitudes of brightness and color.
How can a black and white image be represented as a bitmap graphic?
The image is split into a two dimensional grid of pixels. If the brightness of the pixel is below a certain value, it is considered black, otherwise it is considered white. Each pixel is mapped onto 1 bit in memory, and if it is white, a 1 is stored, else a 0 is stored. (Sometimes it is the other way round)
