    Exercise 1: What is the function of the secondary memory in a computer?

    a) Execute all of the computation and logic of the program
    b) Retrieve web pages over the Internet
    c) Store information for the long term, even beyond a power cycle
    d) Take input from the user

    Exercise 2: What is a program?

    Exercise 3: What is the difference between a compiler and an interpreter?

    Exercise 4: Which of the following contains "machine code"?

    a) The Python interpreter
    b) The keyboard
    c) Python source file
    d) A word processing document

    Exercise 5: What is wrong with the following code:

        >>> primt 'Hello world!'
          File "<stdin>", line 1
            primt 'Hello world!'
                               ^
        SyntaxError: invalid syntax
        >>>

    Exercise 6: Where in the computer is a variable such as "x" stored after the following Python line finishes?

        x = 123

    a) Central processing unit
    b) Main Memory

        x = x + 1
        print(x)

    a) 43
    b) 44
    c) x + 1
    d) Error because x = x + 1 is not possible mathematically

    Exercise 8: Explain each of the following using an example of a human capability: (1) Central processing unit, (2) Main Memory, (3) Secondary Memory, (4) Input Device, and (5) Output Device. For example, "What is the human equivalent to a Central Processing Unit"?
