2.1 algorythms

1. computational thinking

   • its a way of understanding complex problems
     • decomposistion
       • breaking the problem down into smaller pieces
         • abstraction
           • removing details that are not relevent to solving the problem
             • algorythmic thinking
               • identifying logical steps from the problem to the solution to produce a reusable algorythm
                 • examples of abstraction
                   • the london underground map is a classic example of abstraction
                     • it focuses on the important details such as stations names and the routes from one to another along the various train lines
                       • the lines are not realistically representitive of the actual paths taken by each train
                         • a map represents something from the real world
                           • it removes unnesercery details (plants,trees,coulor of houses anything not important
                             • icons in a WIMP GUI are examples of abstractrions
