New Perspectives Classic Labs
USING FILES
In this Lab you manipulate a simulated computer to view what
happens in memory and on disk when you create, save, open, revise, and
delete files. Understanding what goes on "inside the box" will
help you quickly grasp how to perform basic file operations with most
application software.
1. Click the
Steps button to learn how to use the simulated computer to view the
contents of memory and disk when you perform basic file operations. As
you proceed through the Steps, answer all of the Quick Check questions
that appear. After you complete the Steps, you will see a Quick Check
Summary Report. Follow the instructions on the screen to print this
report.
2. Click the
Explore button and use the simulated computer to perform the following
tasks.
a. Create a
document containing your name and the city in which you were born. Save
this document as NAME.
b. Create
another document containing two of your favorite foods. Save this
document as FOODS.
c. Create
another file containing your two favorite classes. Call this file
CLASSES.
d. Open the FOOD
file and add another one of your favorite foods. Save this file without
changing its name.
e. Open the NAME file. Change this document so it contains your name and the name of your school. Save this as a new document called
SCHOOL.
f. Write down
how many files are on the simulated disk and the exact contents of each
file.
g. Delete all
the files.
3. In Explore,
use the simulated computer to perform the following tasks.
a. Create a file
called MUSIC that contains the name of your favorite CD.
b. Create
another document that contains eight numbers and call this file LOTTERY.
c. You didn't
win the lottery this week. Revise the contents of the LOTTERY file, but
save the revision as LOTTERY2.
d. Revise the
MUSIC file so it also contains the name of your favorite musician or composer, and
save this file as MUSIC2.
e. Delete the
MUSIC file.
f. Write down
how many files are on the simulated disk and the exact contents of each
file.
