TEACHER TIP

If you have a PDA, use it to demonstrate the operating system. What features are similar to those of Windows and Mac OS? Which features are different?

FIGURES

• Figure 4-23

SECTION C: FILE BASICS

File Names and Extensions

LECTURE NOTES

• Demonstrate both Windows Explorer and My Computer to students, with file name extensions showing.

• Show the connection between the icon used for the file and the file type.

• Review the view options in My Computer and Windows Explorer to display files.

• Show the Open and Save As dialog boxes in applications such as Microsoft Word, Paint, WordPad, and PhotoShop. Click the Files of type list arrow to show the formats the application can open and which ones they can save. Some applications convert file formats when you use the Save As command and choose a different file type.

TEACHER TIP

File naming conventions differ by operating system. Have students start by learning the conventions only for the operating system they use in your school labs, then build on their knowledge for other operating systems. Trying to memorize rules for all the operating systems at one time may be difficult for a novice user.

Finding files with specific names and specific folder locations is difficult for students. Have students save a file in Microsoft Word and then try to find the folder location. Most students do not look at the Save In drop down box when saving files.

FIGURES

• Figure 4-24, Figure 4-25

CLASSROOM ACTIVITIES

1. Group Activity: Divide the class into two groups and challenge the groups to list as many file extensions as they can think of or find on classroom computers. Which group can list the most?

2. Quick Quiz:

• A(n) _________ is an optional file identifier that is separated from the main file name by a period. (Answer: file extension.)

• True/False: Each operating system has a unique set of file-naming conventions. (Answer: True.)

• True/False: Reserved words cannot be used as file names. (Answer: True.)

File Directories and Folders

LECTURE NOTES

• Directories and subdirectories are a troublesome concept for many students. Windows Explorer is a dramatic aid to help students visualize the structure of files on a disk.

• Use the cardboard box analogy: Each directory is a box. Each box has a name. Boxes can contain papers (files) or folders (subdirectories).

• Once students understand the idea of directories, explain that files are not physically stored in a structure that reflects the directory tree.

• Although some people like to use a directory analogy in which each directory is like a slice of a pie or disk, the files in a directory are not necessarily stored in a certain physical area of the disk. The directory structure is a logical model that helps us think about the organization of files on a disk.

• Show how Windows Explorer and My Computer provide file size and date information in Details view.

TEACHER TIP

File size becomes especially important when disk space is limited. The file date becomes important when you are tracking work and want to make sure you have the most recent copy of a file. Compare file sizes of Word documents to Paint files and explain why the sizes vary.

FIGURES

• Figure 4-26

CLASSROOM ACTIVITIES

1. Assign a Project: Have students research why the main hard disk drive is usually referred to as drive C.

2. Quick Quiz:

• A(n) ________ is a section of a hard disk drive that is treated as a separate storage unit. (Answer: disk partition.)

• True/False: The main directory is called the base directory. (Answer: False.)

• ___________ is usually measured in bytes, kilobytes, or megabytes. (Answer: File size.)

File Formats

LECTURE NOTES

• Explain that most programs, such as Microsoft Office XP and 2003 automatically add the extension to the file name.

• Review the reasons given on page 209 for files failing to open as expected. This is a common source of frustration for new users of computers, especially those who receive an e-mail attachment, for example, for which they do not have an application that can open the file.

• Using an application such as Microsoft Excel or Access, show students how to convert a file using the Save As dialog box and using the Export command on the File menu. Compare these two methods and discuss when to use one or the other.

TEACHER TIP

Remind students to be careful when renaming files, and remind students of the implications in changing a file extension. Demonstrate this by having students use a file in one format, such as My File.bmp, and rename it so it has a different file extension, such as My File.doc. Ask them to try opening the renamed file in Paint and then in Word and discuss what happens and why.

FIGURES

• Figure 4-27, Figure 4-28, Figure 4-29, Figure 4-30, Figure 4-31, Figure 4-32

CLASSROOM ACTIVITIES

1. Assign a Project: Have students find a specific folder and list three file names with different extensions. Students should note the folder name as well as the files.

2. Quick Quiz:

1. A file is a named collection of _____ that exists on a storage medium, such as a disk, CD, DVD, or tape. (Answer: data)

2. True/False: A file name extension is an optional file identifier that is separated from the main file name by a comma, as in Help,com. (Answer: False)

3. The maximum length of a file name using current versions of Windows is _______.

a. 8-character file name plus an extension of 3 characters or less

b. 31 characters

c. 255 characters

d. 256 characters

(Answer: c. 255 characters)

SECTION D: FILE MANAGEMENT

Application-based File Management

LECTURE NOTES

• Demonstrate how to use the Open and Save dialog boxes in a typical Windows application. Take time to show all the information the Save dialog box provides—location for the file, file name, and file type—or use Figures 4-33 and 4-35.

• Mention that many programs allow you to set a default folder location to save files. Give an example: a personal folder in Word will always be saved in C:\Personal\Yourname. Word allows you to set this folder as the default folder using Options from the Tools menu. Once this is established, all files will save to this location. If the need arises to save files to other locations, then you would locate the folder in the Save In drop-down box.

FIGURES

• Figure 4-33, Figure 4-34, Figure 4-35

TEACHER TIP

The best way to understand how to manage files using the Open, Save, and Save As commands in a Windows application is to have students perform these tasks themselves. If possible, let students work in the lab to create a short document about file basics, for example. Have them save the file on a CD or zip drive with a name such as File Basics.doc and close the document. Then ask them to open the File Basics document, add information about managing files, and use the Save As command to save the document as File Basics and Management.doc.

CLASSROOM ACTIVITIES

1. Assign a Project: Have students write a brief explanation of the difference between Save and Save As.

2. Quick Quiz:

• A(n) __________ is a piece of information that describes a file. (Answer: file tag.)

• True/False: You can name a file and specify its storage location in the Save As dialog box. (Answer: True.)

LAB ACTIVITY

• Refer students to the New Perspectives Web site for a Student Edition Lab called “Managing Files and Folders.”

File Management Utilities

LECTURE NOTES

• Explain that file management utilities help you manage files by providing a “big picture” of the files on your computer.

• Explain that although file management utilities vary from one operating system to another, they rely on the same basic principles.

• As students become familiar with the concepts of device letters and folders, they will be able to navigate through most computer systems.

FIGURES

• Figure 4-36

CLASSROOM ACTIVITIES

1. Quick Quiz:

• __________ utilities give you the big picture of the files you have stored on disks. (Answer: File management.)

• True/False: You can change the way the Windows file management utility shows files. (Answer: True.)

File Management Metaphors

LECTURE NOTES

• Use Figure 4-37 to show how drives, folders, and files fit the tree metaphor.

• Ask students if they have developed any metaphors for themselves to help them understand how to organize or find files.

FIGURES

• Figure 4-37, Figure 4-38

CLASSROOM ACTIVITIES

1. Assign a Project: Have students sketch the file structure they will use for their personal files.

2. Quick Quiz:

• What are two metaphors typically used for storage on personal computers? (Answer: Filing cabinet, tree.)

Windows Explorer

LECTURE NOTES

• Discuss what Windows Explorer looks like as a program. On a demonstration computer, show the Windows Explorer window, pointing out the two panes and explaining what they show. The left pane shows the big picture view of the computer’s hierarchy of storage devices and folders. If you click a folder in the left pane, for example, the right pane shows the folders and files in the selected folder.

• Discuss moving, copying, and renaming files and folders in Windows Explorer. Make sure students understand that a file’s true name includes its path as well as the individual file name; demonstrate this in Windows Explorer by creating files with identical file names and extensions, but store them in folders with different names.

FIGURES

• Figure 4-39, Figure 4-40

TEACHER TIP

Point out the Details pane and explain how this can help identify and distinguish poorly named files, saving time that would’ve been spent opening and perusing the file to identify it.

CLASSROOM ACTIVITIES

1. Assign a Project: Have students open and explore Windows Explorer.

2. Quick Quiz:

• True/False: You can rename files in Windows Explorer. (Answer: True.)

• True/False: You can copy files in Windows Explorer. (Answer: True.)

• True/False: You cannot delete files in Windows Explorer. (Answer: False.)

File Management Tips

LECTURE NOTES

• Review each tip with the class. Go around the room and ask students to explain why he or she thinks the item is important.

• Ask for examples of errors or file disasters that could be attributed to ignoring these tips.

FIGURES

• Figure 4-41

CLASSROOM ACTIVITIES

1. Assign a Project: Have students list the guidelines for file management. A complete list is provided on pages 217-218.

Physical File Storage

LECTURE NOTES

• Emphasize to students that even when a disk is defragmented, the physical organization is still not equivalent to the conceptual organization. Although a directory analogy in which each directory is like a slice of a pie or disk works as a logical model, all the files in a directory are not necessarily stored in the same physical area of the disk. A logical model is not meant to accurately reflect the physical organization of the disk itself.

• Explain that although a disk is physically laid out in tracks and sectors, a cluster is the smallest unit accessible by most microcomputer operating systems. In Windows, a cluster is composed of two sectors.

• Students may skip over Figure 4-44 without studying it thoroughly. Spend some time talking about it. The main point is that the index file tracks the location of files on disks. Help your students see how the file Jordan.wks is stored in different sectors.

• Use Figure 4-42 to show what an operating system does when it formats a disk.

• Demonstrate how to defragment a disk by using a floppy disk or other removable disk that needs to be defragmented. Start the Disk Defragmenter tool, use the Details view to explain what Windows is doing as it defragments, and then let it run for the length of the class. At the end of your class session, examine the progress or results of the defragmentation.

• Discuss what happens when a file is deleted. Is it really deleted, or can it be recovered? Show students how to use the Recycle Bin folder to find files that they have deleted. Show how to erase files from the Recycle Bin, and discuss file shredder software that truly eradicates data from your disk.

TEACHER TIP

Remind students that defragmenting disks might be done at the end of the business day or overnight to avoid use of the computer.

The conceptual model of folders and files does not reflect the physical reality of the way in which files are stored on a disk. Students may confuse this statement with the explanation of fragmentation discussed later in the section. Remind students that random-access storage allows files to become physically divided up all over a disk’s surface. Although this does not mean that the file itself becomes unreadable, it does make it harder for a drive to read the file efficiently. The process of defragmentation helps to organize the disk by rearranging the files on the disk so that they are stored in contiguous clusters.

FIGURES

• Figure 4-42, Figure 4-43, Figure 4-44, Figure 4-45

LAB ACTIVITY

Refer students to the New Perspectives Web site for a Student Edition Lab called “Maintaining a Hard Drive.”

CLASSROOM ACTIVITIES

1. Assign a Project: Have the students draw a diagram of the hierarchy of the folder structure of their own PC, if they have one. Students should compare their results with other students.

2. Quick Quiz:

1. File management utilities often use some sort of storage _______ to help users visualize and mentally organize the files on disks and other storage devices. (Answer: metaphor)

2. True/False: The pane on the left side of the Windows Explorer lists each of the storage devices connected to your computer, plus several important system objects, such as My Computer, My Documents, My Network Places, and the Desktop. (Answer: True)

3. When working with Windows Explorer, you can select noncontiguous files by holding down the _______.

a. Ctrl key and clicking each of them

b. Alt key and clicking each of them

(Answer: a)

c. Shift key and clicking each of them

d. mouse and pressing the down arrow key

/SECTION E: BACKUP SECURITY

Security Backup Basics

LECTURE NOTES

• Use Figure 4-48 to evaluate the strengths and weaknesses of each backup device.

• Review external hard disks and their advantages in the backup process. Why are these useful? Because they can be stored in a secure location, such as a safe, or a fireproof vault.

• Disaster can happen to anyone. Refer to the following table to show how easily data can be destroyed:

| | | |Intentional data |

| |Unintentional data loss |Inaccurate data |loss or damage |

|Factor | | | |

|Operator error |X |X | |

|Power failure, surge, |X | | |

|or spike | | | |

|Damaged hardware |X | | |

|Natural disasters |X | | |

|Computer virus | | |X |

|Trojan horses | | |X |

|Worms | | |X |

• Emphasize the importance of a plan. Refer students to Figure 4-46 to help them formulate a backup plan for themselves. Suggest a schedule for backups, e.g., every other Friday, or just before lab.

• Explain that many users rely on network backup. Network backup can be as easy as copying a valuable file to a folder on a shared drive on your server. While this protects your important data against the failure of your own personal computer, it might not protect you against a network failure, or a disaster such as a fire in your building, for example.

• Review Internet backup sites.

TEACHER TIP

Another form of Internet backup is simply to e-mail a file to a friend, or to your own Internet e-mail account such as a Gmail account. Any form of backup is better than none!

FIGURES

• Figure 4-46, Figure 4-47, Figure 4-48

CLASSROOM ACTIVITIES

1. Class Discussion: Ask the class if anyone has ever been the victim of a data disaster, such as mistakenly copying an old version of a document over a new version, losing data on a hard drive, or having a virus wipe out files. What could’ve been done to prevent the loss?

2. Quick Quiz:

• A(n) _______ stores files needed to recover data that’s been wiped out by operator error, viruses, or hardware failures. (Answer: backup.)

• True/False: Your backup schedule depends on how much data you can afford to lose. (Answer: True.)

Data File Backup

LECTURE NOTES

• Demonstrate a backup. In Windows, use the Copy Disk menu option (on the File menu of My Computer or Windows Explorer). If the Backup tool has been installed, you could use that instead.

FIGURES

• Figure 4-49, Figure 4-50

CLASSROOM ACTIVITIES

1. Class Discussion: Ask the class what types of files they currently back up and onto what medium. Using Figure 4-50 to aid the discussion, ask if their backups are as complete as they should be.

2. Quick Quiz:

• True/False: You can simplify the backup process by storing important files in various separate locations. (Answer: False.)

• True/False: Restoring from a data file backup is very difficult. (Answer: False.)

• True/False: You should only be concerned with backing up data files you create. (Answer: False.)

LAB ACTIVITY

The New Perspectives Lab “Backing up Your Computer” deals with issues that relate to this section of the textbook. You might want to go through the lab during class time if you have a computer with a projection device. Or, assign this lab for students to do on their own.

System Backup

LECTURE NOTES

• Are these reasonable backup methods for a home computer? Who might be likely to use one of these types of systems?

• Explain that software developers often back up to a second hard disk.

• Go over the pros and cons of full backups vs. differential backups, where only those files that were added or changed since your last full backup session are backed up.

• Depending on a student’s computer configuration, it might be easier to rely on distribution disks to restore software, rather than going to the trouble to create a full system backup.

FIGURES

• Figure 4-51, Figure 4-52, Figure 4-53

CLASSROOM ACTIVITIES

1. Assign a Project: Have students write a paragraph comparing and contrasting full, differential, and incremental backups.
