V. Read the text and render its contents.
Each tiny dot on the screen of a computer is called a picture element, or pixel. Images and text are formed by combining a large number of pixels.
In a bit-mapped display, the dots displayed on the screen correspond, pixel by pixel, with bits in the main memory of the computer. The bits are held in an area of the memory called the «refresh buffer» and are stored in groups that represent the horizontal and vertical position of the pixels on the screen and whether the pixels are on or off.
On monochrome systems, one bit in this «map» represents one pixel on the screen and can be either «on» or «off» (black or white). On colour systems, each pixel is a certain combination of the three primary colours: red, green and blue. The total number of colours, which can be shown on the screen, is called the colour palette. The size of this palette depends on the graphics adaptor, a separate videocard that converts the bits into visual signals. A graphics adaptor with 1 bit per primary colour can generate up to 8, or 23, colours. A graphics adaptor with 8 bits per primary colour can generate 16,7 million, or (23)8 colours.
