Samsung’s new phones will have flexible screens


Samsung‘s new mobile device lineup will feature flexible screens starting in 2012, the company announced today.
In its quarterly earnings call, Samsung’s vice president of investor relations, Robert Yi, told investors, analysts and press, “The flexible display we are looking to introduce sometime in 2012, hopefully the earlier part. The application probably will start from the handset side.”
After flexible-screen mobile phones roll out, the company plans to introduce the same technology for tablets and other devices.
In January 2011, Samsung purchased Liquivista, a strategic acquisition that will allow it to produce the kinds of displays that were announced today. Liquivista made electrowetting display technology, which is used to create mobile and other consumer electronic displays that are bright, low-power, flexible and transparent.
Flexible screen technology was also a focus of Samsung’s in March, when Yongsuk Choi, director of Samsung Mobile Display, gave an overview of the company’s future mobile device plans. At that time, Choi said most of the flexible-display technology Samsung was working on was still in very early stages.
Flexible displays have been on the fringes of up-and-coming mobile technologies for some time. For example, we saw a bendable e-reader from Plastic Logic back in 2008.
More recently, Sony, in particular, has shown some interesting work in the field, demonstrating its first flexible display at CES in early 2009 and showing off advanced, thinner, more flexible displays just last year.
Still, flexible screens aren’t something we’re seeing on the mass market yet; we wonder if consumers will warm to the idea when Samsung takes the wraps off these new devices.
Samsung recently surpassed Apple as the top smartphone manufacturer, shipping 27.8 million smartphones last quarter. Altogether, Samsung’s current share of the smartphone market is 23.8 percent.

How to Protect Your Computer from Harmful Malevolent Program Viruses ?


Nowadays, every internet user is engaged in downloading, uploading or exchanging files, pictures, movies, etc. over the internet. People have become so busy in all this that they seldom care about the bugs and viruses that get into their computers while downloading stuff. In order to avoid any viruses or bugs, special care needs to be taken. Since, if the user will use the system carelessly, he/she will end up with files behaving abnormally, messages popping up on the screen, operating system getting corrupt or valuable data being lost.

Essentially, malevolent programs are such computer programs that are designed to have undesirable or catastrophic effects on our systems. A computer virus is the most malicious of the computer troubles. Generally, it gets into your computer when you try to run a program to which the virus is attached. These malevolent programs then spread into your PC like a biological virus and infects your files and data. They also have the capability to transport themselves from one PC to another and affect the computer’s performance badly.


Now in order to protect your computer from such malevolentprograms, one needs to take some serious measures, which include installation of a suitable antivirus program on your workstation. This installation should preferably be done soon after the purchase of the computer so as to avoid any damages. If you don’t have any antivirus software installed to your computer, you are placing your PC at severe risks. Therefore, you can also install the software on your computer anytime to prohibit further destruction.
How To Protect Your Computer From Malevolent Programs :

There are a lot of good quality antivirus software’s that are available for purchase or download over the internet like McAfee, Kaspersky, Norton, Bitdefender Antivirus, etc. To facilitate the proper execution of the antivirus software, the user should purchase a registered version of the program from an authorized dealer.
One can buy CD’s of these antivirus software’s from the market or could purchase them online as well. Many people tend to avoid buying these programs because of their lofty price tags but once installed, they can save the user from the harmful viruses that could affect the operations of the system.
Nonetheless, to ease the burden of the users, there are several discount schemes offered for the customers online. People could purchase these vouchers and get a discount on different antivirus software’s that are present in the market. There are various discount coupons like Bitdefender coupons, Kaspersky coupons, MacAfee Coupons and so on, which could be bought to gain some compensation over the price.
Avoid Malevolent Viruses With Proper Maintenance  :

The security of the computer is not an easy task. After acquiring desirable and appropriate antivirus software, the user also needs to keep a constant check on the PC. Always make sure that you perform an antivirus scan in normal mode as well as the safe mode. Safe mode is considered to be the best among the two modes because when you run your operating system in safe mode, your system identifies and eradicates the viruses more smoothly as compared to the normal mode. Therefore, users at all times should do an antivirus check in safe  mode.
Moreover, the users should try adopting the habit of downloading the frequent updates related to the antivirus software they have installed; as it will keep their software up-to-date, letting it discover latest threats.
Apart from the antivirus programs, the users should also install a firewall in their workstations as it allows them to have authorized communication while blocking unauthorized users’ access. Usually, the computers that come equipped with the Windows operating system have firewall software installed in them already. However, one can also download or buy firewall programs from the internet if needed.
As it is commonly said prevention is better than cure, the same goes for your computer as well. The users at all cost should avoid downloading files or documents from unreliable websites. Even if you are downloading files from a trusted site, run a quick virus check on them prior to the opening or installation so as to avoid any unexpected trouble.
Identifying the viruses that are present in your computer is of utmost significance. In order to keep your system safe from all such harmful and malevolent programs, the user should install the antivirus software and perform system scans regularly. All hard drives, files and folders should be scanned, and viruses should be removed immediately if found to hinder proper system functioning.

10 reasons why PCs crash U must Know


10 reasons why PCs crash U must Know

Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications."

You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?

1 Hardware conflict

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.

If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears twice, two devices may be using it.

Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored. The best way to fix this problem is to remove the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to discharge any static electricity.

To be fair to Mcft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out of them. There are plans to increase the number of IRQs in future designs.

2 Bad Ram

Ram (random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need replacing.
