How are programs executed?

Programs written in high-level languages need to be translated into machine language before they can be executed. This translation is done by either a compiler or an interpreter, depending on the programming language.

Study Notes

Programming Languages

  • A program is a set of instructions following the rules of the chosen language.
  • Programs make computers useful by providing instructions for specific tasks.
  • Programs contain lists of ingredients (variables) and directions (statements) on how to use them.
  • Programming languages are vocabularies and grammatical rules for directing computers.
  • Programming languages create computer programs.
  • Programming language terms often refer to high-level languages (BASIC, C, C++, COBOL, FORTRAN, Ada, Pascal).
  • Programs must be converted into machine language to be understood by the computer.

Program Conversion

  • Programs need to be translated into machine language.
  • Compilation converts a high-level program into a complete machine code program.
  • An interpreter reads and converts instructions one at a time, translating into the machine code while running.
  • High-level languages use compilers or interpreters to translate and run programs, making them usable by humans.
  • Programming is a process including writing, testing, debugging, and maintaining source codes.
  • Source codes are written in languages such as C++, Java, etc.

Programming Skills

  • A programmer writes, tests, and maintains programs for computers.
  • Key skills for becoming a programmer include programming, writing, reading comprehension, critical thinking, computer/electronics knowledge, mathematics, oral/written expression/comprehension, deductive reasoning, and information organization.
  • Programming involves effective communication, identifying the strengths/weaknesses of programming approaches, and effectively structuring/classifying information.
  • Programming requires knowledge of numbers, their operations, relationships, and associated applications, like arithmetic, algebra, geometry, calculus, and statistics.
  • Programming languages include machine, assembly, and high-level programming languages.

Language Types

  • High-level languages are closer to human languages, while low-level languages are closer to the computer's language.
  • Machine language consists of binary digits (bits) understood by computers.
  • Machine language is difficult and less efficient for humans, using only numbers for instructions.
  • Assembly language uses keywords and symbols resembling English, simplifying programming but adding complexity, since it needs translation.
  • High-level languages use instructions resembling everyday language, simplified for people to use.
  • Programming languages need translation from high-level instructions into machine language format for execution, either by compilers or interpreters.
