Keyboarding is used as communication tool to convey information to others. Before the Invention of typewriter, Man first recorded his ideas and messages on stone, then on leather, and later on paper which was much lighter than either stone or leather. The use of paper allowed man to send his thoughts to other people many kilometers away. The preparation of these messages, however, took a long time, even with the use of pen and paper. Then the typewriter was invented in 1829..
