but if you continuously compete with yourself, you become better.

Mouse is an input device that is used to commit command into
computer memory. It is also known as a pointing device.
The mouse is one of several pieces of hardware you will be
using when interacting with the computer. It works by its pointing on the
screen and judging whether it is pointing or resting on the right item.

Physical Maintenance of computer
Physical Maintenance
Don’t touch the screen.
The oils from your fingers will
leave fingerprints that are hard to remove. Avoid touching the screen if you
can. To clean an LCD screen try a dry cloth for dust or a moist cloth for
stuck-on stains. If the dirt is persistent, pick up an LCD cleaner or cleaning
cloths sold at most computer and electronics stores. Don’t spray anything
directly on the screen, and do NOT use regular surface cleaners. Make sure you
only press gently, as pressing too hard may damage the screen.
Keep drinks and food away from the
computer.
This is tough, but one cup of
coffee or can of pop can ruin your keyboard. Also crumbs can be a problem. To
clean a keyboard, use compressed air, or a small clean paint brush to brush out
lint and other debris.

Backing up your Computer
Backup
Backing up your computer is an
important thing to do if you want to keep your files. Computers can malfunction
for a variety of reasons, including viruses, hardware malfunction, theft, and
home disasters. You never know when one of these will strike, so you should
back up your information on a regular basis. (This is also useful when
transferring to a new computer.)
Computer users have a range of
backup options to choose from.
1) Online storage. Storing
your information online is one of the easiest ways to backup your information.
With the push of a few buttons, the program copies your data and stores it in
an online database.
Pros:
1.
Ease of use.
2.
Access your documents from any computer that has an
Internet connection.
3.
No possibility of physical theft on your end or
destruction in flood or fire.
4.
Some have automatic backup schedules.
5.
Share certain files with other people.
6. Automatic
file restoration process.
Cons:
1.
Yearly fee for service.
2.
Slight possibility of ambitious hackers gaining access
to your private files. Although a good company should have safe-guards to
prevent this.
2) Offline storage programs. Purchasing
a program that will back up your data is convenient, but you have to provide
the storage medium. (CDs, DVDs, external hard drives, flash drive, floppy
disks, etc.)
Pros:
1.
One-time fee when purchased. (Plus the cost of the
storage medium.)
2.
Ease of use.
3.
Automatic file restoration process.
Cons:
1.
Possibility of loss if theft, fire, or flood occurs.
2.
You provide the storage medium.
3.
All files may not fit on storage medium.
3) External hardware. External
hard drives, CDs, DVDs, flash drives, and floppy disks can all be used to back
up data.
Pros:
1.
Cost is minimal—only need to purchase storage medium
and no additional software is needed.
Cons:
1.
You have to do all of the work with copying/pasting.
2.
All files may not fit on storage medium—two or more
devices may be needed.
3.
Possibility of loss if theft, fire, or flood occurs.
Note: Keep in
mind that these options only transfer your files and not your programs.
If you ever need to restore your computer to its former glory you will need to
reinstall the programs yourself. Make sure you keep your installation discs and
product keys! Many programs can only be installed on one PC. If you run into
problems when reinstalling a program you can always contact the manufacturer
for help.

of the computer’s user accounts.
All
information on this computer – backs up a copy of all data
(documents & settings) for all users as well as the Windows operating
system files to be used if your system should crash at a later date. It will
not help if your hard drive dies.
Let me choose what to back up - allows you to choose which files you back up.
Choose a location to save your
backup to by clicking in the Browse button.
Note: When
choosing storage media for your backups keep in mind that a floppy disk
(1.44MB) will hold approximately 600 pages of text. It is recommended that if
you are backing up large amounts of data (i.e. pictures, movies, all data on
computer) to use an external hard drive or large flash drive. A CD (700MB) or
DVD (4.7GB) can also be used, but the data must be written to your
computer’s hard drive or an external hard drive first. Once completed, the
backup file can be burned to a CD or DVD. You cannot burn to a CD or DVD
with this utility. There are two types of CDs--a CD-R allows you to save
data to it one time whereas a CD-RW allows you to add, change, or delete data
as needed.
Once you have designated where you
want to save your backup click Next to
continue.
The final screen will display the
settings and storage media choice you made. Click Finish to execute the backup.
Disk Defragmenter
Disk Defragmenter
Defragmenting your hard drive is a
long process but it is also a very important one since it can speed up your
computer and gain disk space by reorganizing the files on your drive.
Why use it?
When you save files or add programs
to your disk, the file system finds the first available space that is large
enough to hold the files. When you delete programs or files they are taken out
of wherever they may be on the drive. So what happens is that as time passes
and files are created, saved, and installed - as well as erased - deleted gaps
of various sizes appear on your disk.
