Final answer:
Instructions written in code that a computer follows are known as computer programs, with their interpretation varying from the physical electronic changes for engineers, to the execution of tasks for programmers, to applications for users.
Step-by-step explanation:
Instructions written in code that a computer follows are called computer programs. At the physical level, engineers may view these instructions as electronic changes within the computer's hardware. Programmers, on the other hand, understand these instructions at the design level, where they conceptualize the instructions as a set of tasks the machine is programmed to execute. Common users interpret the activity as the computer performing various functions, like word processing or solving equations.
Furthermore, the analogy that compares computer program + input history to what a computer will do next with genetic make-up + experience to what a person will do next enlightens us about the deterministic nature of both computers and human behaviors at a basic level.
It is also interesting to note that the word 'code' can refer to various systems beyond programming languages, such as the genetic code used by cells to make proteins or Morse code, which represents letters as patterns of sound.
