You want to prevent the four "two fingers" to steal the laptop of his? However, if something bad may not happen despite all your efforts, the last thing you want is how to protect data on computers. Of course, you do not want "strangers" to access the personal data of their song would be better if you take back the laptop is stolen or lost their. To not be stolen while on transfer, you should fit in a pocket with protective functions, but looks are not laptop bags for guys in less recognizable. But somehow you always keep an eye on your computer and it's better if you keep the machine with you (on a table or bag strap). Many users have a habit of placing and holding the laptop between the two legs when sitting, but no longer use the computer. At home, you should protect your computer by a cable and lock. Most laptops are equipped with small grooves for mounting a protection key and you can easily buy other types of cable lock at the shop computer components. When staying at the hotel, you should bring your laptop with you when you go out. If the hotel is safe or security cabinet, you can take the computer. Another way is somewhat inconvenient, but very safe as you can send the laptop in the reception area. However, others are carefully protected laptop is stolen; so make safety fencing for data Data on the machine, especially those carrying sensitive data like bank accounts, trading statements, business contracts, customer lists, etc. .. Of course, you never want to lose data . Get in the habit of regularly backing up data to an external storage device and never to drive common laptop bag. In fact, users often to backup disk at home and copy the files needed to work on a USB thumb drive. Also, you can also use online backup as Mozy or IBackup. You can refer to the article "Sharing files impartial" (ID: A1002_69) and "Online Store" (ID: A0608_119) to be more selective backup data over the Internet.

COMPUTER noise generator
If you run into this situation is almost certainly a cooling fan inside the machine to work loose or excessive than normal to "low graphics" system. However, it is also capable of signaling a more serious failures, such as hard disks. A damaged hard disk emits about to crack than a normal hard drive; so it is better that you make available a full backup of your hard disk.(See more at find.pcworld.com/71156). Next, start checking the fan to identify the perpetrator of the noise (or something near it loose) and clean up any dirt. Depending on you're using laptops or desktops, see further instructions below.

Desktop
First, turn off, unplug from the electrical outlet, then open the computer case. Plug in the machine, power on and see if can identify any fan loud or not. If in doubt, try checking the "old" is the Cardboard Tube Test: Find a cardboard tube used to scroll (if not, you get the press and curl). Applying an input to the ear, while the other direction to the moving parts in your computer. If determined to be noise from the fan, your computer off, unplug and check the fan and associated hardware there is certainly no tightening screws. You should also check around and inside the cage fan. If you do not find anything unusual heat can "force" the fan works harder than normal, and dust can also cause overheating with the fan as well as the entire system. You can use a small vacuum device or air spray to clean the dust inside the machine and fans. During the implementation, so read directions carefully to avoid damaging the machine's other components, especially the cable break.

Laptops
Find and remedying this situation with the laptop is somewhat more difficult - because other than desktop computers, laptops are not designed so that users can repair or upgrade. With a laptop is running, you can pick up and use your ears to hear the sound emitted. Try to determine where the noise comes, or use a check Cardboard Tube Test as above mentioned. When the machine is off, use a spray air into the heat vents to clean dirt. However, many users believe that this is not a good idea because dust will be blown into the machine. Note, you should not arbitrarily open to release a laptop fan repair or cleaning the machine in unless you are sure that you can control any situation that may occur. If you prefer to manually do things like that are adventurous you first go online and see how to manipulate as well as repair experience. PC World 3 / 2011

Although Skype is not officially belong to Microsoft (because the deal worth 8.5 billion of them waiting by the authorities), thus making the takeover attempt was criticized even more. "It seems that the Skype problem occurs worldwide. You know, now it is a product of Microsoft, "one wrote on Twitter. Page Technology The Inquirer wrote, "voice services over Internet protocol (VoIP) and chat Skype has been having problems all over the world and continues to fail to sign, led many to believe that the recent acquisition by Microsoft is obviously a disaster.

Speaking of printing over the network, we can split into two concepts: in the intranet and in the Internet (also known as online in the cloud). This article focuses on the online printing services cloud was only two big names bring to the user.

Google Cloud Print - free for all users

early in 2011 recently, Google launched Google Cloud Print services, printing services, a cloud is quite convenient for everyone. Cloud With Google Print, you do not need a special printer equipped with support functions in the network cloud, no extra cost to buy any software whatsoever. All you need is a computer to install Google Chrome browser, connect to printers other vendors, Internet access, and laptops running OS Chrome or mobile OS Android, IOS (currently only supports IOS Android 2.1 or higher and 3 or more).Users can print documents directly from applications on the web or phone mobile. Then, the document will be transferred to Google's servers, and finally transferred to computers connected to the printer to print the document to the user. Installation Cloud Google Print service is simple, fast and easily with the ordinary user. First, you must install the Google Chrome browser latest version.Then, establish a connection to the Google Cloud Print Services option in the browser. And, you can enjoy the ability to print documents with Google cloud Cloud Print.(You can consult the manual installation for details at: http://pcworld.com.vn/T1224712.) After successful installation, from laptops running OS Chrome or mobile OS Android, IOS, you can open the email and print to printers connected. Note, for in the mobile device, you must sign in with the account used to connect to the Google Print Services Cloud. You can also print documents PDF format files attached to email.

HP ePrint - "email is sent to print out the"
One pioneer in the field of printing clouds (cloud printing) is HP. Quarter 2 / 2010, HP has launched HP ePrint technology, allows users to print documents and images anywhere, anytime from any mobile device with Internet connection function and email. Each HP ePrint features will be issued an email address (after the purchase, the user can connect the printer to the Internet to activate). Users can send documents to print to HP ePrintCenter data center, and the document will be sent to the printer user's home or office. According to HP, the whole process only takes about 25 seconds. Suppose you are traveling and need to send the document to print to the printer at the office, but then this printer is off, then your document will go ? Do not worry, in that case, the documents should remain in your service on your server HP ePrintCenter. You can access web pages and services in the document when the printer is ready. You can set up its own list of email addresses that are allowed in your ePrint printer to avoid email spam case to the printer wasting ink and paper. You can also change the email address of your HP ePrint through HP ePrintCenter site. The advantage of HP ePrint is no need to use a computer to perform the printing process. Users also need to install printer drivers on mobile devices. EPrint this feature can be used with mobile devices like Apple's iPad and iPhone, and also with the smart phone operating systems (smartphones) such as Palm, Android and Windows Mobile. On May 11/2010, HP has product range launched the first new ePrint printer market in Vietnam for individual users and businesses, including the line color inkjet AIO OfficeJet, line color LaserJet printers and DesignJet large format printers for for the architectural, engineering and construction. The new printer is also equipped with touch screen HP TouchSmart users to easily access the application online and print in the paper quickly. service point or two if a user is ordered in the computer or printer is turned off, the command will be stored in the corresponding service server and the print will be automatically executed when the computer and in the open again.

Unfortunately, the transfer and synchronize files between Mac and PC board are not easy to implement. There are many different ways to do this, but no way was perfect - each one has its own drawbacks. This is one area where Apple needs to continue to improve. And while waiting for Apple to do this, the following are some ways to help you transfer files between your different devices.

On the one hand, this feature only works with applications that support it. All creative tools for iPad as Pages, Keynote, Numbers, GarageBand and iMovie are using iTunes to transfer files back and forth. Some applications of the company Tuesday, as the e-book reader, text editor, and creative communication tools, too.

But different applications to use iTunes in many ways; for example, Apple's application requires you to select "Save to iTunes" (saved in iTunes) when saving a document; other applications automatically put the file into iTunes.

Worse is that you must regularly perform self-synchronizing files. Now, would you know to carry out any operation: iPad direct connection to your Mac and open iTunes. Choose your iPad in the iTunes source list and click on the "Apps" (application). Scroll down the list of installed applications and look under "File Sharing" (file sharing). Select the application you want to copy files from there, to the files of the application appears in the "Documents" (documents) of it. Drag one or more files to the desktop while holding down the "Option" (optional) to copy them onto your desktop, or use the "Save To" (saved) to open the transmission of voice system. If you update files on your Mac and want to send the file back to iPad, you must drag the file has changed it back to iTunes, the document list of suitable applications.

It is not simple at all.

When you need to synchronize files, you can use Dropbox service (2GB free). The service is fine for syncing files between computers. But active sync files between your Mac and iPad, why?

Unfortunately, the iPad service Dropbox has not been adequate, but not due to deficiency of service. Dropbox application, like many services other cloud storage (including MobileMe iDisk), to easily access any files and folders you stored with the service. Dropbox application makes it easy to view any data in formats compatible with IOS, including Word and Pages documents, PDF, text files and images. In addition, Dropbox and similar applications give you the option to open the file synchronized with compatible applications iPad; example, you can use Dropbox to submit application materials to the Pages word processor.

The drawback of this procedure is not able to send files were updated on the Dropbox from the Pages. Due to restrictions in the activities of the IOS now, the cloud storage application only works one way on the iPad.Transfer files from the Dropbox on an application is simple, but you can not send files back Dropbox is the updated file is complete.

One way to accomplish this. In applications that support WebDAV, such as Pages, you can use DropDAV service (2GB free) access to your Dropbox folder. DropDAV allows you to interact with Dropbox files through WebDAV traditional connection. Since Pages lets you open files from a remote WebDAV server, you can get the document and editing it on your tablet. Remember that you are working on a copy locally. When done, you have to manually save and publish documents on the WebDAV server by DropDAV created. This is the easiest way to get experience on the iPad Mac Dropbox, but not perfectly.

There are few applications that support iPad built for cloud storage (most commonly Dropbox). Indeed, the Dropbox web page that lists more than 130 integrated applications for service in many ways.

There are many text editors iPad compatible with Dropbox, including $ 5 Elements (~ 100,000), iA Writer $ 1 (~ 20,000), and Textastic price 10 USD (~ 200,000). With the editor, the synchronization seems to be made smooth; changes are saved directly to the Dropbox; changes you make on your Mac instantly get on the iPad.IPad is no need to connect to your Mac; process is very easy to implement.

In addition to the text editor, the list of applications compatible with Dropbox also includes word processing program such as DocumentsToGo price 17 USD (~ 340,000 VND), QuickOffice price 15 USD (~ 300,000 VND), and the price Office2 6 USD (~ 120,000 VND), the file reader as ReaddleDocs cost 5 USD (~ 100,000) and GoodReader cost 5 USD (~ 100,000), the application notes as DropVox $ 1 (~ 20,000), Audio memos $ 1 (~ 20,000), Mobile Recorder $ 1 (~ 20,000), and Smart Recorder price 3 USD (~ 60,000), and many other applications. When the application allows you to open and save documents directly to the Dropbox, you can easily manage the files normally.

The application of the Apple iPad is not integrated with Dropbox, but still work with MobileMe iDisk. Unfortunately, the combination with this application does not perform well against the best application of the Dropbox application. The publication is very similar to iDisk file sharing feature (File Sharing) of iTunes; you can copy your files to a remote server, instead of keeping a single copy is always synchronized.

But what Apple's iWork suite lack of uniform quality, the application tried to redeem themselves in sync in many ways. Apart from iDisk, you can share documents via web iWork iWork.com, submit documents to iTunes, or copy documents via WebDAV. There is no option listed above is simply the application Dropbox. DropDAV above services can help you a little, but lack all the characteristics of sophisticated applications that integrate Dropbox can provide.

Unless and until Apple with other vendors to build two-way synchronization features into their applications, the second email is the best possible application.

Of course, unlike email synchronization feature real-time real than iTunes File Sharing; you still have to send copy files back and forth, and make sure that is always working on the final version. But the method used email several advantages compared to iTunes.

Firstly you need to connect to your Mac iPad. Secondly, the email is marked with the date, so you do not need to learn that you are working with the latest version or not, you can know exactly what documents you submitted at any time.

If you plan to use the file transfer via email, you should also create special rules in the mail application you choose to handle this particular type of correspondence. For example, in Gmail you can create a filter to find the messages sent and received, and the message that has attachments. The messages have tag Files and go into the archive (archive) by the way, the Mail application on the iPad will display these messages are packed neatly in the same directory.

If you can access the remote FTP server (the company that provides network server or by other means), the iPad your Mac and can connect to it. But you'll have to download the file to your Mac when you want to work with that file. Instead, you can configure your Mac into an FTP server. To do this, select the option system "Sharing" and enable "File Sharing". Then click "Options" (option) and select "Share Files" (file sharing) and "Using FTP Folders" (folder using FTP). Optional system (System Preferences) will tell you the FTP address of your Mac. Please note that, unless your house has a static IP address and your router is configured correctly, you can hardly or can not connect to your Mac is used as FTP server, if iPad your not on the same wireless system.

Using FTP from iPad method can be used, because it ensures that you can work on only one copy of a file at a time. But if you can not access the file when you connect online in places other than your home, it's a serious problem.

There are many applications - including iFlashDrive $ 2 (~ 40,000), and Briefcase Price 5 USD (~ 100,000) - allows you to use iPad as a virtual USB drive, so you can transfer files from the iPad. These applications and other similar applications can usually connect to your Mac (if you enable file sharing) via the local Wi-Fi; other applications can connect using Bluetooth. Some applications also support remote access, including functionality to connect to server SFTP (Secure FTP).

But this method still seems like the iTunes File Sharing feature to use the wireless system. You can copy files back and forth, but to perform this process manually.

The sad fact is the file manager on the iPad be difficult. You can see the synchronized real-time two-way real sense of how, when you use one text editor to connect with Dropbox can be used for the iPad. But the solution to synchronize files are used for various other applications are not suitable for the iPad. Until Apple provides a better solution, you may still use the text editor when possible, and use email to pass through the other files.

Google and Mozilla are testing versions of Chrome and Firefox browsers capable of hiding the web address (URL).The feature is currently still in beta testing.

Here's how it works, the advantages and disadvantages of hidden features URL address bar

In the Canary Chrome browser version last, you activate the "Compact Navigation", right click on any tag (tab) and select "Hide the toolbar." URL address bar will disappear. To display the address bar, click on the tab is open.

In the version of Chrome Canary 13, enter the words "about: flags" in the URL, choose Compact Navigation and restart the browser. Home Ars Technica says this feature only works with Windows Canary version, currently not supported on Mac OSX.

Mozilla is also testing similar features to Firefox.

An add-on for Firefox 4, called LessChrome HD, will hide all the toolbar below the tabs (tab) is open, you do not use them. The toolbar will reappear when you move the mouse pointer on the card is opened, or when you switch tabs. The user can set LessChrome HD from the Add-on Firefox .

Pros: Feature hiding the URL that allows users netbook and tablet PCs have more screen space, which shows much more than web pages.

Limitations: In relation to security issues, since most web visitors want to know where they are, any web page ... in order to avoid becoming the target of phishing attacks.

Wolfgang Gruener, conceivably from Tech, said that once you access the web page you want, you probably will not need the address bar anymore, unless you're worried about security issues.

According to StatCounter, both Firefox and Chrome currently holds 43% of the browser market, so they can promote the use of hidden features URL address bar, is less common. However, Microsoft is also holding half the browser market with Internet Explorer, and the company does not intend to allow users to hide the URL bar in the future.

Replyuint32 is not available the model name of the language. Indeed uint32 is the name of a class defined in the System namespace of the environment. Net. Module should use uint32 code must use "using System;". When you use the Visual Studio environment. Net to create visually a Windows Form, it will make available the source code for Form frames respectively, the frame contains the source code available on "using System;", whereby you use uint32 class is without error. When you program in VC + + language, the source of most of the VC + + Project will not access the System namespace, so can not use class uint32. If you want to use class uint32 the code VC + +, you must create a Project-type CLR (eg CLR Console Application), declared on "using namespace System;" before taking class uint32 to declare the variable data of the program.

AnswerYou did not state his wishes, so we make that the following two: 1. Want to check if there is anyone using the machine while you're away do not? 2. To use certain services on-line to check whether anyone is at home using your computer? If you want one that is going on, just boot the machine, use the file browser (Windows Explorer) see the last revised by the file c: \ pagefile.sys (or any *. log file in the folder c: \ windows), if the time happens when you're away, then surely someone has used your computer , and how users can not know exactly. Note that you must set the mode for displaying file system and hidden files to be able to view the file on. If you want that 2 is currently no service, but the idea of writing software to solve This problem is quite simple: write a small monitoring software and set it to run automatically each time the boot, the software periodically send an e-mail (the content is not important, there also) e-mail on your account. Somewhere, you use the computer check your mailbox, checking the time of the e-mail e-mail they send to know who is at home are not using your computer.Currently the use of phone Mobile also very popular, so instead of sending e-mail to your account, the software on your computer monitor can create and send SMS messages to your mobile phone.

COMPUTER NOT STARTING
Many readers often "blamed" for the virus (computer) system crash when "blue screen of death" (BSoD) or when a notification that no operating system exists on the hard hard, even notice the system has no hard drive at all.This concept came about in 1990 when the virus as Leonardo could cause the computer will not boot and can not access the data. Moreover, if the computer is infected with Leonardo (spread by floppy disk) was launched on March 6, the virus will wipe out all data on your hard drive. But with a number of knowledge and experience, users easily recover data. The creation of the malware (virus or malware in general) is the hobby of a number of savvy computer users (private hackers or hacker) with many different purposes (mostly bad). Hackers can use your computer to send spam, infect other malware into your computer, or even used as a "rear" to carry out attacks as denial of service (DDoS). More dangerous, you have control of your computer, hackers can easily steal the account password and credit card information. the opinion of many security experts and the experience of the writer shows If the computer can not boot it is not likely caused by malware. You can refer to the article "Computer does not boot" (ID: A1102_102) for more ways to troubleshoot your computer.

Secure WiFi network
If not controlled, strangers (or any application) to access your WiFi network, make sure they will "steal" bandwidth; most recognizable signs of a slow-speed Internet access and the risk of stolen information, the data will occur if access to personal computers. Therefore, to enhance security for personal WiFi network, the first thing to do is make sure no one be accessed without your consent. Most routers (router) or access point mode support encryption like WEP, WPA or WPA2, you should consult the documentation accompanying the device options are used. The security settings for the WiFi network requires a password you create (as "healthy" as possible) to hackers or other users is difficult to predict. Of course, you must remember to enter the correct password for all devices, from desktops, laptops, smart phones, the first multimedia playback, format the hard drive or NAS supports network printer wire. Also, ways to limit the access of users are using the router's MAC address filtering. Each device will be available NSX assign a particular MAC address, simply enter the address to the list of allowed network connections. With machine running Windows, open the Command Prompt, type ipconfig / all, then press Enter. MAC address is the value in the "physical address". PC World 4 / 2011

Understand a simple way, the 3D (three dimensions) or three dimensional images will have more depth (spatial coordinate system x, y and z) while 2D images are displayed as system plane coordinates (x and y axis). Thus, the depth of the main differences between 2D and 3D images. Basically, the technology displays 3D images based on the principle of the left eye only see the image for the left eye and right eye see only the image for the right eye. Every eye will see two separate images, different colors, different angles. Image signal is transmitted to the brain and then, the 3rd dimension will appear by the processing capabilities of the brain. Currently, the world's existing technology and 5 show the 3D technology is the pair Colour Image (Anaglyph) appeared in 1850, technology-polarized (polarized) in 1936, technology can make (lenticular) in 1940, interference filter technology (Infitec) in 2003 and LCD shutter technology (LCD Shutter) appeared in 2006. Readers can refer to a number of articles about 3D technology as www.pcworld.com.vn/A1003_76 and www.pcworld.com.vn/G1002_20 or "160-year history of 3D" magazine e + + 01/2010 , t. 45. CONFIGURATION ENTERTAINMENT 3D addition to the technology is designed "special treatment" 3D movie in theaters as polarized, Infitec, according to the criteria article, we only mention the construction of a 3D-based entertainment system NVIDIA-based 3D Vision. In addition to the 3D movie technology, the NVIDIA 3D Vision also supports more than 400 games with 3D genres. A significant point is that NVIDIA 3D Vision is compatible with standard 3D Blu-ray movies and can "upgrade" to the NVIDIA 3D Vision Surround with 3-screen 3D Ready 120Hz LCD Vision; readers spoiled " immersed "in the 3D world. Refer to detailed technical requirements of 3D Vision Surround in www.nvidia.com/object/3dv-system-requirements-surround-technology.html Note that not everyone likes because they enjoy 3D effects certain activities are not beneficial to health such as headaches, dizziness, eye strain, etc. ..

Ministry "kit" NVIDIA 3D Vision
The "kit" NVIDIA 3D Vision technology, including a shutter 3D glasses active (active shutter glass), and receiver / transmitter radio communication (Radio Frequency) coverage about 30.5 m. NVIDIA 3D glasses using the method of displaying the image sequence (Alternate-Frame Sequencing), first frame for the left eye and then the frame for the right eye. LCD shutter glasses will do this by closing / opening them one eye (60 times / second for each eye). Refer to details in www.pcworld.com.vn/G1002_87 glass.

Screen
Vision 3D glasses work with the frequency (refresh rate) up to 120Hz, it requires the display must also have a frequency from 100Hz upwards. Also, to show the film in high definition (High Definition), you need to select the screen resolution of 1920x1200 or higher gain. The simplest, readers can choose the standard screen 3D-Vision Ready and Full HD 1080p, such as LG W2363D BenQ XL2410T 120Hz 120Hz LED or LED.

Graphics
addition of 3D glasses and display standard, the NVIDIA 3D Vision technology also requires a compatible graphics card graphics using the graphics chip (GPU) and NVIDIA. Test at Test Lab shows the midrange card to use as GeForce 465 GPU, 460 (ID: A1008_54) was from 8500 to 8700 points in 3DMark 06 (1600x1200 resolution), is fully equipped with the features of the new graphics card, capable of handling quite good graphics, game configuration to meet the crisis at moderate resolution. Additionally, the midrange graphics card is relatively quiet, consumes little power as the high card.

Chassis
system similar multimedia entertainment (www.pcworld.com.vn/A0806_160), the chassis is equally important options, which affect the selection of other hardware devices. A good external chassis design appeal to users, the design fully "closed" to reduce noise while still "open" to ensure the ability to dissipate heat, limiting temperature increase inside the chassis. You should select the type of tank is located (desktop), compact, nice to put them in harmony as the entertainment devices other civil. Remote control and support facilities to help users easily control and manage the process of photography, watching movies, listening to music. The point to note is the barrels are often limited ability to support hardware and high price.

Power
Recalling the challenge is before selecting the source, you must calculate the total capacity of the system should meet. The best way is to use the utility to support as extreme.outervision.com / psucalculatorlite.jsp, thermaltake.outervision.com / index.jsp or antec.outervision.com. In addition to cooling efficiency and reduces noise when operating, you can select sources equipped with large cooling fans or even non-fans (Fanless mode).

Processor
Like it does not matter, the processor is Intel's choice of the masses. Last March the past, Intel Vietnam has introduced the second generation Core processors (codenamed Sandy Bridge) to design the 32nm, transistor Hi-K metal gate 2nd generation, providing high performance and save more power consumption, image processing capabilities of the integrated graphics are better improvement. But according to the criteria article, we still need a discrete graphics card to show 3D movies and gaming.

Motherboard
Currently, Core 2 generation using socket 1155LGA therefore only suitable for BMC chipset H61, H67, P67 and Q67. In the BMC of H61 chipset does not support multi-card graphics technology, H67 and Q67 only supports ATI CrossFireX while P67 supports both NVIDIA SLI and Quad-GPU ATI CrossFireX Quad-GPU, meet the ability to display images 3 screens at the same time as NVIDIA 3D Vision Surround technology.

CPU fan
noise is not a major problem in computer gaming or office, but with computer multimedia entertainment, you should change the CPU fan a better (except for Sandy Bridge Core processors used i7) to help reduce noise to the maximum.

Memory
HTPC Similarly, memory (RAM) is not important hardware configuration in 3D entertainment. You can choose the low-voltage RAM Kingston HyperX RAM LoVo or high-end line of the famous brands such as Apacer, Corsair, Crucial, Kingston, Super Talent ... depending on individual needs.

Hard
Drive a few hundred GB capacity will quickly be "filled" with full HD movies (HD movies accounted for an average of about 4-10GB). To store 3D HD content (side by side or over / under) and presentation software, you should be equipped with built-in hard drive capacity, such as Western Digital 2TB Green WD20EARS or additional storage devices external storage for easy storage.

Mouse, keyboard
you want to "rewind" quick clips or listen to favorite songs, but "afraid" to move. Keyboard & Mouse Wireless is the appropriate choice, giving you more flexibility in controlling the computer. The point to note is that the wireless mouse with high latency, not the best choice of gamers.

Believe it or not, you should apply the following recommendations:

Use headphones to restrict close the phone to the ear. Also, you can use the phone's speaker.

Some studies, for those who frequently use the phone indicates that electromagnetic waves can affect the quantity and quality of sperm. In addition, mothers who are pregnant should also limit hold the phone with you.The more people put the phone away, you guessed.

Send / receive messages from the phone will generate less radiation than when you make a receiver / caller.

Take the phone off when not in use. Many users use the phone as an alarm clock and often put them at the beginning of beds. Scientists believe that this should not, instead you use an alarm clock.

When the battery is low or in areas with weak signals, the device emits much more radiation.

Electromagnetic waves may affect young brains are not good, so do not use your phone as a toy. If your child likes to play, turn off the phone before them.

Also, if you choose to buy mobile phones have low-level radiation 

If you are installing a new printer, please follow the instructions on the enclosed CD. During installation, you should perform the sequential steps of the Add Printer wizard will help establish a new printer your default. To install a printer as the default in XP, first click Start.Printers and Faxes. In Vista, to do this, click Start, and Sound.Printers Panel.Hardware. In Windows 7, click Start.Devices and Printers. Right-click the printer you like, select Set as default printer. Right-click the icon again to make sure the settings are correct (when the menu is open, a check mark will appear with the words "Set as default printer"). If not right-click menu out "Set as default printer", you double-click the printer icon to display the Print Queue. Click Printer and select Set as default printer in the menu. A check mark beside the menu item or icon printer means that as the default printer. You can change these settings at any time. Even then the default setting, you can still print with other printers are installed on the internal network or on a computer system you. To print to a printer Monday, just press File.Print.Print dialog box will display all the printers are installed. Select a printer and click OK. PC World 5 / 2011

Windows
Most third-party firewalls are disabled or status reports on, but the Windows firewall (Windows Firewall) will not be aware of this situation. Take the following simple steps to make sure Windows Firewall is opened. 1. Check your taskbar (taskbar): Look at the lower right corner of screen red shield icon. If visible, click the icon to determine if the Windows firewall off or open. 2. Open Windows Security Center: Even if the icons on the taskbar that Windows firewall turned off, you do not know what information about firewalls. For more information, go to Start, Control Panel. When the window opens, click the Security Center. Alternatively, click Start, select Run ..., type firewall.cpl in the search box, click OK. 3. Check the Windows Firewall: The Windows Security Center, you will see the area used to manage settings for Windows Firewall. Green said the firewall open. Red means the firewall is off, in case you need to click On, to open the Windows firewall.

Surf safely with Flagfox
Hackers can easily create a fake website, but can not assume the server location. For example, you can access a web page identical to Bank of America site, but if the site is located (host) in Uzbekistan, you should not enter the password on that site. Flagfox for Firefox (find. pcworld.com / 71,649) will help you determine the location of, the Web server that hosts national and web and logo of the national flag will appear above the address bar. When you press the left mouse over the flag, geographic information web page that appears. If you right-click the flag, will appear as a list of tools Bit.ly, SiteAvision, Web of Trust, and Whois. You can go to Tools. Add-ons, options to add more options to add-on.

Recovering data from damaged disk
drive notebook (laptop) is corrupted, replace another hard drive but want to retrieve the image data stored on a hard drive failure. Use Recuva (find.pcworld.com / 71,650). This is a very useful utility for rescuing data stored on corrupted hard drive. However, you can not plug into the laptop hard drive to restore corrupted data. Buy an external hard disk box support USB hard drive in IDE or SATA port, costs around U.S. $ 15 (~ 300 thousand) to $ 20 (~ 400 thousand). Attach the hard disk drive is damaged box, then connect the USB port on the laptop hard disk box. It is important to recognize utilities Recuva is corrupted hard disk drive mounted in the box or not. If not, you use the utility to recover data.

Rename the printer
you have two machines in the same company, such as Brother, including one to close your printer. When printing text, sometimes you forget the printer located near you to select the printer in for two similar names, such as Brother HL-2170w and Brother MFC-490cw. Fortunately, in Windows 7 name change machine in very simple.(The previous version of the operating system also allows you to rename the printer). Click Start.Devices and Printers. Right-click the printer to change the name, and click Printer Properties. Name the printer will light up (highlight), press Delete and type in the new name of the printer. Click OK. For printer sharing (share), changing the printer name is more complicated. People are connecting the printer to disconnect (disconnect). Once finished, rename the printer connected to the printer (add). PC World 5 / 2011

On 1/6/2011, the date of IPv6 world (World IPv6 Day), there were hundreds of companies, agencies and universities participating in testing IPv6. The event has attracted the attention of many users around the world. Here are some of the questions and answers about using IPv6 addresses.

To communicate on the network, we need the IP address. Similar to the way we send mail, the letter should clearly state the sender, destination, each packet (data) when sent over the network also includes two information: source IP address (the sender), place destination IP (destination). There are two types of IP: Public IP (public IP) that allows computers to communicate on the Internet, private IP (private IP) allows computers to communicate in the local area network (LAN).

The computer will "see" each other based on IP address. Because IP addresses are numbers, so to help users easily remember the domain name system DNS (Domain Name System) will help resolve domain names and IP addresses. For example, when you enter pcworld.com.vn domain name, DNS will resolve domain names into IP addresses allow computers and servers for "see" each other. See all NAT servers and "excess" NAT .

There are about 4 billion IPv4 addresses, length 32 bit binary. IPv6 addresses are 128 bits long binary, so there will be about 340,000,000,000,000,000,000,000,000,000,000,000,000 IPv6 address. Experts figure that the address can be considered as infinite.

Cricket Liu, vice president of its software architecture Intetnet InfoBlox, saying that if you are in Asia, this will soon happen. APNIC (Asia-Pacific Network Information Centre) has allocated the IPv4 address of the last.

According to Cricket Liu, in the worst case you can not access the web page, appears the message "server not found". Vegoda Leo, director of resources of ICANN, said the notice you receive will be sent to the browser vendors.

You can still access the web page IPv4 normal, because the service provider will offer a variety of tools to transfer content to just work on IPv4-only access to computers using IPv6. One of the tools that NAT64, built on a network of service providers. When the domain name server found no IPv6 address corresponding to the web page you want to visit, NAT64 will "capture" IPv4 address of the site and "compressed" into the IPv6 address, which helps your computer, visit Visitors by IPv6, can understand.

This issue is irrelevant, because in a few years, the company will switch to IPv6, and most companies will use the "dual network configuration." Dual network configuration will include the software necessary to help the communication between IPv4 and IPv6 systems conveniently. This system is most organizations are using IPv6, use.

Martin Levy, chief strategy officer of the IPv6 Internet service provider Hurricane Electric, said it expected to provide NAT64. With this service, businesses can run their servers on IPv4, and Hurricane will connect to the server for users to use IPv6. All businesses need to do is add a path (entry) in their DNS server.

Enterprises and service providers continue to use traditional techniques to maintain NAT IPv4 addresses they are using. According to experts, IPv4 and IPv6 will coexist with each other on the Internet in the next few years.

Traditional NAT maintains information access, helps more computers to use a public IP address, communicate with other computers through the Internet. However, the ability of the device integrates NAT functions, is limited. If the access session (session) exceeds the capacity of the device, the session will be "left behind", the access to websites and services on the Internet will slow down and "flickering".

According to Martin Levy, NAT64 does not maintain information access and how it works unlike traditional NAT.However, technology also can cause bottlenecks tighten. Von Martin Levy for if you put a box between the data stream, the less this box will also affect the quality of data transmission between the two first.

World IPv6 Day attracted many technology companies like Google, Facebook, Yahoo and many businesses, agencies, universities, and to test the possibility of using IPv6 in practice as well as find out the technical issues.
