Document Summary

Images: we rely on images for information, entertainment, and visual appeals. Origins of images: non-digital mediums (paper copy of a photo, photography (images uploaded to a file on the computer, clip art images (images created and saved to a file on the computer) Numbering systems: binary: a numerical system containing only 0s and 1s, octal: a numerical system containing 8 digits, decimal: a numerical system containing 10 digits, hexadecimal: a numerical system containing 16 digits (including alphabets a f) Bit: fundamental unit of information in a computer system that uses binary. This is because computers are electronic devices that have only two possible states: on high voltage or off low voltage. Digitization: process of translating piece of information into binary bits: the information takes a series of values that equal either 0" or 1". More bits used to encode colors mean more colors available to assign to a picture (y = 2number of bits)
