How do you remove the ethernet phone jack plug from the computer?
It is not a phone jack plug, though it is very similar. All you have to do is squeeze the tab and pull the plug out. If there is a rubber sleeve, you might be able to squeeze through it, or you may have to slide it out of the way. You would likely only run into problems if the plug is broken. In that case, it might require tools, and you would have to be gentle as to not damage the socket.

What are the requirements before formatting your computer?
The first thing you need to know before formatting a computer is that formatting will delete all the data in the drive which you intent to format. You may format your entire system or format only selected drives. It depende on your needs and conditions. If you need to repartition (i.e., to reallocate spaces and change file systems) your disk, you may need to format more than one drives.
You need to make sure of the following things before formatting:
- Decide whether to format the whole disk or only selected drives.
- Take backup copies of all important data. You may use CDs, DVDs, USB flash drives or secondary hard disks. (Remember: formatting a drive erases all the data in it.)
You may do formatting in two ways:
- Use the bootable disk (CD or DVD) of any operating system like Windows xp or Ubuntu.
- Boot into an installed operating system and format selected drives (for example, by going to My computer in Windows OSs).
The first option should be used when you need to format either the whole hard disk or the drive in which your operating system is installed. The second option can be used when you don't need to format the drive in which operating system is not installed.
Another thing you need to know about is the file systems. You will be asked to select a file system when you are going to format. Windows operating systems usually use FAT-32 and NTFS file systems. Look in the related links section to know more about file systems. You need not worry much about file systems. Older versions of Windows used FAT-32 file system. NTFS was introduced with the Windows NT operating system.

Why are loose carpets dangerous near a computer?
Static can build up in the user and transfer to the computer, causing damage.
Why was the laptop made in silicon valley?
Silicon Valley is the term given for the South Bay portion of the San Francisco Bay Area in Northern California, USA. It is the home of the some of the largest technology corporations in the US. So it is only natural that laptop computers would be invented and produced in areas like Silicon Valley and nearby Palo Alto where there are a lot of computer-related corporations.
If you are asking why there are laptops, it is because scientists and other professionals needed to be able to take their research and data with them. Computer manufacturers benefited greatly from portable computers, and it helped them do their work. So thus they eventually became available to ordinary consumers.
What part of a computer plays cds?
The part of a computer that plays CDs was traditionally called a CD-ROM. Now, it is likely to be a CD-RAM device or DVD-RAM device since most computers have CD or even DVD burners these days.
On the lighter side: A woman called a computer manufacturer asking how she could get the "cup holder" on her computer replaced. They company assured her that they didn't install cup holders on their computers, and she insisted that they did. So they asked her what it looked like. She said it had a button on it and when she pushed the button, this tray came out, and she could sit a cup in there. The technician excused himself and the woman could hear a lot of laughter in the background. When he returned, it took all he had to keep from laughing while informing her that what she broke was the CD-ROM drive.
When did they change the computer?
Technology does not stand still. The computer was changed to make it better.
What are the other parameters for the sfc command besides scannow?
Here are all the SFC commands according to Microsoft:

What is an artifact in computer graphics?
In computer graphics, artifacts are visual anomalies, unwanted blemishes on the screen, or errors produced by image compression or manipulation.
Sometimes malware produces visual artifacts. For instance, one spyware application produced a green dot in the upper left hand corner of the screen. Maybe its writer added that during development to trace whether it was installed on the test computers or not and forgot to remove it.
Computer games are notorious for showing image artifacts. The Hall of Mirrors Effect ("HOM effect") is often produced in no-clipping mode in first person shooter games, when the player is out of bounds, or the vertices in the game map are open due to a design flaw. So you might see several images stacked together and some white flashes as you move the character. In the early days of computer games, sprite collisions and player-missile collisions were common. It was common in Breakout to have several of the balls on the screen, though often with parts missing or for the paddle the player moves to show damage.
If you convert something to JPG, you often get a loss of quality and some bit of a haze around parts of the image. This problem is most evident around text and faces. This pattern of distortion is usually similar in every image that is compressed using JPEG. That is known as Huffman noise.
In digital photography, artifacts are areas of distortion or missing parts of an image that are specific to the exact camera used. Cameras use a CCD chip, and unfortunately, the chips are often produced with defects. So as you take photos, the same pixels will be missing in every photo and act like a fingerprint. So if someone uses a digital camera to help commit a crime, perhaps extortion, it is possible to trace the images to the camera.
What are computers you don't see?
Embedded computers are typically computers that you don't generally see. They are found in appliances, in cars, inside implanted medical devices, and so on. There might also be such things called nanocomputers where they are nearly impossible to see with a naked eye.
The first thing you do when dealing with customer complaints is remember the customer identifies you with your company.
Even if your company is at fault and the fault is totally out of your control, most customers won't see it that way. You = Your Company.
Next, you make sure you've noted the customer's name and note other details as you go along, so you don't have to keep asking them, what was your name, again? What was the product, again? and so on.
As the customer is telling you their problem, be sure to continually reassure them you're listening and taking it all in and your main aim is to resolve the problem. The customer needs to know you're on their side. Never, ever, be defensive. No matter how dumb the customer might sound, or how unreasonable, or how angry, always let them know they have a right to complain, that you're listening, and that your job is to fix things for them.
Even if after they leave, or get off the phone, you say to your colleagues, wow, that was one stupid/demanding/insane customer, while you're with the customer your only focus is on how you can help them, and letting them know this is your only focus.
Never, ever, start trying to defend the company, its service or products. Never, ever, ever, say things like, we've never had any complaints before, or, I've never heard of this problem. Be positive about your company and its products, but never in such a way as to suggest the customer is wrong to complain.
Stay reassuring and friendly, but not too friendly. Remember their name, and call them by it: yes Mr. Smith, no Mr. Smith, I understand, Mr. Smith.
How you handle a dissatisfied customer right at the start can make all the difference between a customer who ends up with a worse grievance than they started with, and a customer who goes away saying, thanks for your help, I'll wait to hear from you, then?
Always remember, the customer is always right. Just as you and your company don't sit around figuring out ways to make customers miserable, so customers don't sit around working out ways to annoy you. When they ring, or call in, they know they're right!
Remember, too, that many people are afraid of complaining, and can start out with the idea you'll make complaining difficult for them. They might sound like they own the world, and any problems with that world are all your fault, but deep down many of them have picked up the phone, or walked in, with a scared feeling that you're going to be obstructive, put them down, make things difficult for them, and - the worst of all their fears - tell them they don't have the problem they think they have. Some people are rude, or loud, or unreasonable, out of nervousness, though it mightn't sound like it.
Your job is to think of ways to fix the customer's problem, or at least to have them believe you (and therefore your company) are doing your best to fix it.
If you have to refer to other people, apologize for keeping them on hold; if you need to call them back, do so as soon as you can. Make sure they've written down your name and know how to contact you, if possible.
All in all, unless you've a complete crazy on your hands who nobody could cope with, don't let them go away mad. They need to go away feeling better than when they first met you.
Next time you talk to them, refer to your notes so they can see you remember them.
And, finally, one really important thing you can do, before you ever get to meet a customer with a complaint: get on the phone and call your company's helpline, the one you're at the end of. Check out how long you're kept on hold, whether there's annoying on-hold stuff they have to listen to, how good the menus and other directions are, and so on. These things can go a long way towards frustrating customers before they ever get to speak with you.
Many companies completely fail to check on what a customer goes through to finally meet someone they hope can help them. Make it your business to know! If a customer was feeling fairly reasonable until they tried to ring you, if they've wasted way too long trying to get through, if the menus and other phone options are confusing or (it happens!) just plain wrong, they'll be in a bad mood by the time they get to you. Understand this and deal with it.
Many companies don't want to know their complaints procedures are making customers mad, even before they make their complaint. Assure the customer you'll let those above know about problems they've encountered in this way, and then use your own judgment about whether - especially as a new employee - to tell the company about it, or to wait until you've been there a bit longer and know your way around. Whatever you decide, at least let the customer know you've heard, and intend to do something about it.
Keep remembering: the way a customer feels about making a complaint almost always comes to depend on you. Keep calm and cool, and be nice; if you keep the right attitude, you'll find you have better luck with customers than your less-thoughtful colleagues.
So, good luck! If you cared enough to ask this question, you're well on the road to being lucky with whatever work you do; I hope the next time I ring a company with a complaint, I get to speak with you!
Laser printer with 300 resolution printing?
300 DPI is a very low resolutioe resolution rating. If this is the maximum resolution for the laser printer that you are looking at, do not buy it if you need sharp (or even acceptable quality) graphics. 300 DPI is the lowest common printing resolution, and dots are easily seen when looking at an image printed. Most laser printers, however have a 300 DPI setting, along with 600 and 1,200 DPI resolutions. The resolution of a laser printer does not matter if you plan on only printing black text, as resolution does not matter in this case.

When should you not wear a wrist strap when working on your PC?
The wrist strap is used to prevent static charge buildup, which can arc from you to the PC, and potentially cause damage.
Because of this, there is no time when you should NOT wear a wrist strap. It may not be needed at all times, but it certainly doesn't cause an issue if you do.
I do not always use this; when it is warm and damp, static charge buildup is less of a problem. Also, if you are working in an area away from things that naturally help build up charge on your person (shag carpet, wool,...), it because less of an issue. But there is always some level of risk involved when working inside a computer and not having this.
When using a vacuum cleaner to blow dirt and dust from a PC you should direct the hose?
Yes, to the main area of dust. I also suggest using an unused paintbrush instead of blowing.
