1. Algorithum

   • Algorithms use control flow to make decisions about which order to do things. They can repeat actions or start new actions based on new information.
   • Computer programs use sequence, selection and iteration to control the flow of the program. These elements allow the program to make choices, change direction or repeat actions.
   • Example: unlock the door,open the door, enter the room, switch on the light, close the door behind you.

2. Programming languages

   • A programming language is a formal computer language designed to communicate instructions to a machine, particularly a computer. Programming languages can be used to create programs to control the behavior of a machine or to express algorithms.
   • high level code is the way people enter the code, so it's the language that people speech
   • Machine code is the way computers are understood what they do and what they are programmed to understand
   • A translator is needed to convert the high end language and the language that the machine uses the reason for this is that the machine cant understand our language and we don't know the computer language.
