Because, using your computer in a darkened room, focuses all the light form the screen straight at your eyes - causing eye-strain, and possibly vision problems. You should always use a computer in a well-lit room (either by natural or artificial light).

The factors are you must realize what uses you need out of your printer. Then you should look up these brands: Cannon, Epson, Hewlett Packard, and Lexmark as they are primary companies that sell cheap. Then you must see that it specifically works out for what you need it to.

What exactly is your question? Servers do have harddisks for data storage. Each server has different numbers of slots and that's how many disks can be on that server. However, some servers are scalable--meaning slots can be added and mapped to the server. Also, if the harddisks are 16GB--you can swap them out for 36GB (dependent on the server's configuration limits). Databases map to these harddisks and that's where the data is stored. Ideally, disks are mirrored or DR (data replication) so if there is a disk failure, a production environment does not become unavailable. The mirror automatically becomes the primary. Fix the bad disk, then switch the paths back. No down time--no data loss. Without a mirror, you have to do a recovery--either as good as your last backup (if no database archive logs) or you can use the last backup and the archive logs to roll forward to that point. Bad thing is with doing a recovery--you do have production down time (at least for that particular object). And companies now equate down time in $$$$.

Peripherals. These are devices that are attached to the computer that a user can interact with in some way, shape, or form - basically anything you can connect to a computer that isn't another computer. Things such as the mouse, keyboard, and scanners allow the user to input data into the computer, while those such as a printer, monitor, and speakers allow the computer to return information to the user. Some devices, such as a headset with both speakers and a microphone built in, play both roles in one device.

A co-processor is a special chip which is used for some special operations like mathematical calculations, graphics and etc in order to reduce the load of the main processor or micro processor.

Well, when you adjust the volume, the Mac plays a feedback sound, it sounds like a pop. To turn of this feature, go to: System Preferences>Sounds>Play Feedback sounds When Volume is Adjusted>Exit System Preferences. Try Now.

If you are pressing random keys and your cursor is not in a text box, your Mac is going to make noise. To change the noise (You can't turn it off) go to: System Preferences>Sounds>Customize System Noises>Exit System Preferences. Try Now.

If it is a clanking noise or something similar, it is probably a hard drive or cooling fan issue. If this is the case, bring it in to an Apple Store to have it fixed as soon as possible.

Tell Me if that works, I also have a Mac, so I'm Right there with you. Go Apple!

A .prn file is about the most useless file type Microsoft have come up with. Windows programmes allow you to 'print to a file' but then give you no way of actually doing anything with the file. If your printer was a PostScript type, then it might be possible to convert the .prn file to a .pdf by renaming it as .ps instead of .prn and running it though a programme such as ghostscript.

Computers will probably be our basis on life. Doing chores. Going to work. Doing work. Even taking a shower. Computer will be our controllers. And soon enough we are nearing the age of hovering cars and houses that are average of sky scrapers. We might even controls computers through our minds. But with those computers, there are viruses so top notch anti-viruses must be used!
