Computer Programs
  • A computer program is a set of detailed,
    step-by-step instructions that tell a computer
    how to solve a problem or carry out a task
  • Low-level language uses binary digits which is
    what the computer understands
  • Can only be run on one machine

Computer Programs
  • High-level language machine independent
  • Must be translated into machine language
  • Compiler translates entire program into machine
    language and then executes program
  • Also checks for errors as it translates
  • Interpreter translates and executes high-level
    language one statement at a time
  • Displays feedback immediately if it finds errors
  • Runs slower than a compiler
