Why a memory cards become defective?
There are millions of reasons. The most popular are static eletricity, dust, humiidity, power adapter (supply) failture, bad technology.
What is are unlicensed radio frequencies?
Those which you can use for free, for instance a tv remote control uses such frequencies.
It is a hard drive data transfer standard. It is supported by most year 2000 and newer mainboards. It has a transfer speed of a maximum of 100MB per second.
Magnetic card reader requires the card to make contact with the reader?
The magnetic card reader will require a credit or debit card to make contact with the reader. The magnetic card reader will read the numbers off of the card once contact is read in order to submit a debit entry from the card to the officiating bank.
How can you copy data from a smart card?
First, select Copy Smart Card from the Smart Card pull down menu and insert the Smart Card into Reader 1. Next, insert the Smart Card you wish to copy the contents of the first Smart Card onto into Reader 2. Then, highlight the objects in the source container that you wish to copy onto the second Smart Card and press OK. After this, you will be prompted for the PIN of the first Smart Card. Insert the PIN into the Reader 1 keypad. Finally, you will be prompted for the PIN of the second Smart Card. Enter the PIN into the Reader 2 keypad. A secure session will then commence and the copying will take place.

-Documentation.
-Evaluation.
Try to give us more details, how did you do format of your hard disk? What kind of operation system did you have? What do you mean by saying that CD won't run? I guess you want to reinstall Windows OS on your PC and get problems with boot CD?
Cooler oil temostat is sowing temperature ok, chacking by gun laser,still same thinks
What is an Air dielectric capacitor?
Capacitors are, in principal, two parallel plates separated by something (the dielectric). This dielectric can be many things, in fact most non-conductive things, air is just one.
Warning, heavy science (way way above my level)

Photo of variable air dielectric capacitor, used to be used to tune radios for example. You can see the plates and air gap.

Why high pitch noise at boot time of HP PC?
I also heard a high-pitched noise on the 22" LCD HP display my brother is using. I'm guessing there may a fan inside that causes the noise.
What are three settings you can change under Device Manager?
In order to change settings in the Device Manager, you must know how to open it up first.
From: http://technet.microsoft.com/en-us/library/cc750187.aspx
"There are two ways to open Device Manager:
Right-click My Computer and choose Properties, then click the Device Manager tab.
Open Control Panel, double-click the System icon, then select the Device Manager tab."
From: http://www.kellys-korner-xp.com/win_xp_dm.htm
"1) Change hardware configuration settings.
2) Change advanced settings and properties for devices.
3) Change resource settings."
Like everything else dealing with computers, you could really mess up the computer if you do not know what you are doing.
From http://technet.microsoft.com/en-us/library/cc750187.aspx
"Be very careful when making changes in Device Manager. You may accidentally disable or change the configuration of a device so that it doesn't work properly. In turn, this may cause your computer not to boot when you restart Windows. Be sure to document all current configuration settings before making the first change to any device."
The question that was asked came from Jean Andrews "Guide to Software Managing, Maintaining, and Troubleshooting."
What is a dual voltage processor?
A dual voltage processor is the type that can use two different voltages. This feature allows a processor to be compatible with more motherboards.
its a video camera that records whatever goes on on your computer screen ........................you can get help by going on to youtube and going to apesrune1 channel and watch the vid about hypercams
What is a timesharing operating system?
A timesharing operating system is one that divides up CPU time into equal slices that can be shared among applications. In the case of a multi-user system, these time slices are shared among users.
How can i tell my computer make and processing speed?
You can tell your computer's make and processing speed by checking out System Properties in Windows. On Windows 7 & Vista, just right click the Computer icon and select Properties.
What is the data path size for a 64 bit processor?
The data path size for a 64-bit processor is 64 bits. This means it supports memory addresses, integer sizes and data paths that are 8 octets wide.
Raw Materials used in manufacture of computers?
The same ones used in making most other electronics:
Is it possible to recover data from physically broken sections of a CD?
A CD uses optical technology to read data stored on the surface of the CD by reading "BUMPS" or semi-reflective "burn" marks on the medium and interpreted similar 1's & 0's binary format just like in magnetic data storage such as that in Hard Disk Drives. It should be possible to recover the data depending on where the data is physically stored. There should be sufficient technology to go about this, There are companies that do this type of work for different purposes. It could be personal data recovery of very important files or perhaps it could be confidential information. Whatever it is that's stored on a disc, if your goal is to make it unrecoverable it would be to completely shred the disc or burn it, you could also achieve this by sabotaging the aluminum like surface area of a disc.
What contributation did Ada Byron make to computing?
Ada Lovelace (1815-1852) was an English mathematician and writer chiefly known for her work on Charles Babbage's Analytical Engines. She wrote what is now recognized as the first algorithm intended to be processed by a machine, and is therefore considered the first programmer.
She was born The Honourable Augusta Ada Byron to George Gordon Byron (6th Baron Byron) and Anne Isabella Milbanke (11th Baroness Wentworth). She married William King-Noel (1st Earl of Lovelace) and became Augusta Ada King (Countess of Lovelace), but is better known as Ada Lovelace.
What is the proper way to disposed of Alkaline batteries?
They should be dropped in a battery recycling bin. Such bins often exist in or near electronics stores. Make sure they accept alkaline batteries. Some only accept rechargeable batteries. Using rechargeable batteries can save you money and greatly reduce the number of batteries you need to dispose of.
Why do your speakers pick up radio transmissions?
Most likely, it's not the speakers themselves but instead, is the receiver/amplifier to which you have them connected. When a piece of electronics equipment is turned on, it's possible that there may be a section of electronic circuit board wire tracing that's the correct length to `tune into' a specific radio frequency. After that happens, it's not much for the electronics to demodulate the sound and pass it along to the power amplifiers and then into your speakers. This is especially true for certain frequencies like CB radio and some closer FM frequencies like the police bands from a passing squad car. The problem is, that most manuufacturers really don't shield the electronics from outside interference as well as they should.
Another possible source could be from the wires you have connected from one device or another to the power amplifier if say for instance, you're using your stereo to amplify the televisions sound, or from a phonograph/CD/DVD player that's also attached.
One of the things you can do when it takes place again, is try repositioning the wires to help eliminate the interference. Sometimes just taking a wire that's stretched out straight and then putting curved sections here and there will eliminate the problem entirely. work with it until you determine which wire is causing the problem. Then you can either buy a replacement and give that a try (something with better shielding) or add some loops in it. It may take some detective work before you accurately find the cause, but it can be annoying.
