  2. Data Items
    includes all the text, numbers,and other information processed by a computer
  3. Processing
    Data items may involve organizing them, checking them for accuracy, or performing mathematical operations on them.
  4. Central Processing Unit
    Is the hardware component that processes data.
  5. Output
    Describes the operation of retrieving information from the memory and sending it to a device, such as a monitor or printer, so people can view, interpret, and work with the results.
  6. Information
    Processed data.
  7. Syntax
    is the grammar of a programming language
  8. computer memory (RAM)
    is the temporary, internal computer storage within a computer
  9. Volatile
    describes storage whose contents are lost when power is lost
  10. Nonvolatile
    describes storage whose contents are retained when power is lost.
  11. Machine Language
    Is a computers on/off circuitry language
  12. Source Code
    is the statements a programmer writes in a programming language
  13. Object Code
    is translated machine language
  14. Compiler or Interpreter

    is a pictorial representation of the logical steps it takes to solve a problem.
  29. Input symbol/Output symbol
    indicates an input operation and is represented by a parallelogram in flowcharts
  30. Processing symbol
    indicates a processing operation and is represented by a rectangle in flowcharts
  31. Terminal symbol
    indicates an beginning or end of a flowcharts segments and is represented by a lozenge.
  32. Loop
    is a repetition of a series of steps.
  33. Infinite loop
    Occurs when repeating logic cannot end
