Killer Applications—
Using Your Operating System and Word Processor

2. FOCUS QUESTION
How can I use my operating system and word processor to work more productively?

3. Operating System
The operating system is the most important piece of software in your computer.
Many functions to help manage computing resources
process management
memory management
file management
network management
device management

4. Process Management
Processing tasks should be scheduled for different times to avoid crashing.
Scheduled processing tasks include
software updates
virus scanning
backup of data to other locations

5. Memory Management
The operating system can be configured to maximize the memory used by programs. This helps to avoid crashing and allows for more efficient multitasking.

6. File Management There are two types of files:
1. program files (applications)
2. data files (documents)
File extensions help to recognize the kind of file you are accessing by the last few letters after the period.

7. File Management (continued)
When naming data files, keep in mind the following tips:
1. Use fewer than 15 characters.
2. Use a symbol to divide sections of information.
3. Include the initials of the author in two characters or less.
4. Identify the subject in five characters or less.
5. Identify the date.
6. Add an extension.

8. File Management (continued)
To organize files using folders and paths
store files in a logical place
think of electronic storage devices as filing cabinets
use folders to make paths that make sense to you
create folders and then subfolders to group your files together
Paths are the set of folders that must be opened to access a file.

9. Network Management
The operating system manages the computer’s connection to WANs, LANs, wireless networks, and the Internet.
Establish network connections using a wizard.
An ISP gives details on what to enter when using the wizard.

10. Device Management
Software called drivers must be installed on your computer to ensure communication between OS and device.
If more than one printing device is connected to a computer, you can select a default.

11. Keeping Things Organized

do not use glass cleaner
For a keyboard
use cans of compressed air or sticky notes
For a mouse

14. Making Things Fit
Defragmenting eliminates gaps and puts file fragments closer to similar file fragments.
Once a month, you should defrag your computer. It can be a lengthy process. Follow these steps:
1. Close all applications and disable screensaver.
2. Start defragmenting software.
3. A message will appear when defragmenting is complete.
4. Enable the screensaver again.

Margins create white space; the page is too busy without them.
We need margins for binders so that words aren’t cut off.
Most printers can’t print to the edges of paper.
You may need larger margins to leave space for comments.

17. Common Word-Processing Features (continued)
Alignment

Tips for reading Help instructions include the following:
1. Read the instructions once without doing anything.
2. Think about what you’ve read.
3. Begin following the instructions one step at a time.
4. If this solved your problem, consider printing and filing the instructions.

25. Editing and Proofreading
Use hard copy to proofread for keying, spelling, grammar, punctuation, and word usage errors. Check for layout consistency. Consider the following:
Have you given too much or too little information?
Have you used jargon that may not be familiar to the reader?
Have you made assumptions about your reader that may be inaccurate?
Use standard proofreading marks.

26. Electronic Collaboration
Many word-processing applications have a feature that will track changes that you make to a document.
This is helpful when working in a group.
Members can choose to accept or reject changes.
