Advanced Gadgets - Need or Trend

Imaging Device , iPhone 5
Advanced Gadgets - Need or Trend


Surely you will be excited if you buy a new advanced featured iPhone 5 after recycling your ancient one. But is it your Need or its just for Trend? 






Advanced Gadgets Need or Trend?
Gadgets

Of course this is actually depend on your needs and requirements what you choose and why, on other hand, do this new advanced gadget suites your personality? Rarely questions these are, but we are talking about why most of people advancing to modern gadgets? Is it theirs need or just its a trend?


Regarding to many survey reports and discussions, most of people using smartphones or even a camera phone for photo-shoot obviously, it means that a camera phone is your need somehow, but buying a smartphone for photo-shoot is either a trend.


Using advanced featured gadgets is very good if it fulfils your needs and the way you will use it, but for trend I should say its just waste of money. No doubt that an advanced and latest technology device gives you more features including security benefits and more reliability as well as user friendly environment. But again depends on your requirements, otherwise it stands in style / fashion category.



So it was all about cell phone devices, now if we talk about operating systems, there are many types of it and also many cases and options which force you sometimes to select only one single operating system for your gadgets to be easily sync with all your stuff around. But to be discussed, which operating system I should select. And again according to your need and requirements you can choose  which suits you most, but don't go and waste your money to buy an operating system you couldn't operate.





Suppose, if you are a good user and know every tweak about Windows operating system and you are going to buy a MacBook, only because you passionate about Mac operating system or just because its a trend  for you somehow, one thing for sure you would give it time to learn its features and again can waste your money for sure, so learning new things isn't bad, but if Windows operating system can give you everything you want then no need to waste your time and money.



Curiosity and eagerness of modern day gadgets isn't objectionable, they are the best one's. But problem is  that if we don't have time to use its full features then why we spend extra money for it?

For example, a person who is using Intel Pentium IV PC just for media (watching movies or listening music) in part time when he free from his work, then he actually don't need to upgrade to Intel i7 Computer, although Intel i7 stands to be more powerful and can give him full HD output. On other hand a Businessman should buy a device which connects him with co-workers & business society, he will get progress reports in Excel format via email hourly maybe on the go everywhere, so if he buy a Smartphone or a kind of gadget which suits his outputs, definitely he can choose a costly device.

Choose what suits you best, choose what fits best inside your budget and even, use an older device for your old days work, and also nothing is headache if you use them friendly.

5 Most Handy Questions about Smartphones

5 Most Handy Questions about Smartphones

The cloud refers to storage at a remote site accessible from the Internet instead of locally on your computer. Backing up data to the cloud is convenient because you can access it from anywhere�

Here are 5 most common questions about smartphones.

How is a Smarphone different from a standard cell phone?

There�s no official definition, but smartphones let you connect to the Internet, manage email, run software (called apps), and often have robust multimedia capabilities to play videos and music and let you take pictures and record video.

What is a �platform,� and why should I care?

A platform is the phone�s operating system (much like Windows is an operating system for PCs) and determines what features the phone has and what apps it runs. Apple�s iOS and Google�s Android are two examples. Because Apple controls both the operating system and production of the phones that use it, upgrading to the latest version of iOS is easy as long as your hardware is fast enough to support it. Android is different because each smartphone manufacturer using it can modify the core operating system and doesn�t always make updates of the latest version available to its customers.

What hardware specifications should I worry about?

The simple answer is to not get hung up on the specs and instead find a phone that does what you need it to do. Does it work with your email? Does it run the programs you want to use? Does it integrate with your existing services such as Netflix? Is it available from a carrier that provides great coverage in your area? Does it have adequate battery life for the type of things you plan to use it for? If the answer to any of those questions is no, it could be the fastest smartphone on the planet and be useless to you.

The said phones, with 1GB of RAM are nice because they can run multiple programs simultaneously more smoothly than can phones with less RAM. Also look for dual-core processors, as they can dramatically boost the speed of apps designed to take advantage of them. Finally, 16GB of memory is plenty for most users who don�t plan to haul enormous music or video libraries around with them, though 32GB or more is better if you plan to use a lot of apps, music, and video.

What�s the difference between 3G and 4G?

There refer to the speed of the cell carrier�s wireless data network. 3G stands for Third Generation standards and 4G for Fourth Generation standards. Each company implements these standards in different ways, so maximum speeds vary. In general, 4G networks let you download data at least 10 times faster than 3G networks do. This is great for nabbing large files or streaming high quality video, although battery life often takes a bit of a hit when 4G is activated.

Some smartphones will let me use the cloud for backup. What does that mean, and should I use that feature?

The cloud refers to storage at a remote site accessible from the Internet instead of locally on your computer. Backing up data to the cloud is convenient because you can access it from anywhere, and most companies employ encryption and backup redundancy to protect your data. If you don�t have an unlimited data plan, set up the cloud backup to only operate when the phone is connected to a Wi-Fi network. Otherwise, you risk blowing through your data plan without doing much of anything with the phone.

The Future of Malware | News

Android , Apple
The Future of Malware | News




The future of Malware | News from �PCadvisor.com�





Future of MalwareSecurity breaches look set to bet worse as hacker groups target smartphones and social media and release more information online. Jeff Vance reports.



Personal information leaked online is becoming an all too common occurrence. For example, Sony suffered a massive breach of its PlayStation Network earlier this year that led to the theft of names, addresses and possibly credit-card data belonging to 77 million users.


If you think the situation is bad now, just wait. Things will get worse as more information is dumped online by mischievous hacker groups such as Anonymous, and cybercriminals begin to target smartphones and social media.




In August, AntiSec (a collaboration between Anonymous and the disbanded LulzSec group) released more than 10GB of information from 70 US law-enforcement agencies. According to Todd Feinman, CEO of DLP vendor Identity Finder, AntiSec wasn�t motivated by money.


�AntiSec doesn�t like how various law-enforcement agencies operate and it�s trying to embarrass and discredit them,� he said.


But, he added, what it doesn�t realize is that when it publishers sensitive persona information, it�s helping low-skilled cybercriminals commit identity theft. Every week, another government department or business has its records breached � some 250,000 to 500,000 each year, estimated Feinman. Few details from those breaches are published online for all to see, however.


While certain high-profile attacks, such as the one on Sony, are intended to embarrass and spark change, the US law-enforcement breach could represent a shift in hacker thinking. AntiSec�s motivations appear to have a key difference, with the attackers consciously considering collateral damage as a strategic weapon. According to Feinman, AntiSec wrote online; �We don�t care about collateral damage. It will happen, and so be it.�




Social Networking




Facebook Malware

Experts say the future of malware is more about how potential victims will be targeted than how it will be engineered. Collateral damage won�t be limited to innocents compromised through no fault of their own.


Have you ever accepted a friend request on Facebook or connected to someone on Linkedin you don�t know? Perhaps you thought it was someone from school you�d forgotten about, or a former colleague whose name had slipped your mind. Not wanting to seem rude, you accepted them as a friend and quickly forgot about it. �When people make trust decisions with social networks, they don�t always understand the ramifications. Today, you are far more knowable by someone who doesn�t know you than ever,� said Kr Hugh Thompson, program chair of RSA Conferences.


We all know people who discuss everything they do on a social network or blog, from eating their breakfast to clipping their toenails. While most of us consider these people a nuisance and may hide their status updates, cybercriminals love them.


�Password-reset questions are easy to guess, and tolls such as Ancystry.com, while not created for this purpose, provided hackers with useful information,� said Thompson.


There are a few areas he believes the IT security industry needs to concentrate on: security for social media, ways to manage the information shared about you, and better methods for measuring evolving risks.




Enterprise Targets



mobile malware and your businessFake security software is the most common type of social-engineering attack that researchers at Blue Coat Systems come across. Chirs Larsen, head of the lab, explained that social network�s aren�t being used only to target individuals.


Larsen outlined a recent attack attempt where hackers targeted executives of a major corporation through their spouses.


The chances were at least one of the businessmen would have a poorly secured home PC that he shared with his non-tech-savvy wife. This would provide the backdoor needed to gain access to the company.


�Whaling is definitely on the rise,� said Paul Wood, senior intelligence analyst for Symantec.cloud. �Just a couple years ago, we saw one or two of these sorts of attacks per day. Today, we catch as many as 80.�


According to Wood, social engineering is by far the most potent weapon in the cybercriminal�s toolbox (automated, widely available malware and hacking toolkits are number two). Combine that with the fact that many senior executives circumvent IT security because they want the latest and trendiest devices, and cybercriminals have many valuable, easy-to-hit targets in their sights.


�Attacks on small businesses are increasingly dramatic because they are usually the weakest link in a larger supply chain,� said Wood.


There�s no sure way to defend against this. Until companies start scrutinizing the cyber-security of their partners and suppliers, they can�t say with any certainty whether or not they themselves are secure. While it�s common for large firms to keep a close eye on their suppliers, with factory visits that result in the implementation of an array of �best practices�, companies aren�t doing this when it comes to cyber-security.




Smartphone Threats



AndroidMalwareSmartphone threats are on the rise, but we�ve yet to see a major incident. This is partly due to platform fragmentation. Malware creators still get better results by targeting PCs or websites.


Larsen believes that platform-agnostic, web-based worms represent the new frontier of malware. Platform-agnostic malware lets legitimate developers do same of the heavy lifting for malware writers. As developers re-engineer sites and apps to work on a variety of devices, hackers can then target the HTML, XML, Jpegs and so on that render on any device anywhere.


Mobile phones are serving as a second identity factor for all sorts of corporate authentication schemes. Businesses that used to rely on hard tokens, such as RSA SSecureID, are moving to soft tokens, which can reside on mobile phones roaming beyond the corporation as easily as on PCs ensconced within corporate walls.


�Two-factor authentication originally emerged because people couldn�t trust computers. Using mobile phones as an identity factor defeats two-factor authentication,� said Marc Maiffret, CTO of eEye Digital Security.


Today, Android is the big smartphone target, but don�t be surprised if attackers soon turn their attention to the iPhone � especially if third-party antivirus programs become more or less standard on Android devices. iPhone demographics are appealing to attackers, and security experts will tell you that Apple products are notoriously insecure.


Apple is reluctant to provide third-party security entities with the kind of platform access they need to improve the security of iPhones, iPads, MacBook Airs and so on. �Apple is very much on its own with security,� said Maiffret. �It almost mirrors late-90s Microsoft, and it�ll probably take a major incident or two to incite change.�


If we�ve learned anything about security in the past 20 years, it�s that another major incident is always looming just over the horizon. With the number of IP-connected devices climbing to anywhere from 50 billion to a Trillian in the next five to 10 years, tomorrow�s hackers could target anything from home alarms and air traffic-control systems to flood control in dams.

ARM Processors to increase Smartphone efficiency

ARM Processors to increase Smartphone efficiency


ARM Processors to increase Smartphone efficiency | PC Supporter



ARM ProcessorSmartphones will no longer have to compromise between performance and battery life. ARM�s A7 microprocessor uses the company�s most energy-efficient chip design to date, and will bring improved performance to entry level smartphones.


Used alongside the forthcoming Cortex A15 in the �big.Little� power-saving architecture, the A7 will also feature in high-end smartphones.


By combining two types of core on the same chip, and assigning different applications to each depending on their requirements, ARM said it can resolve the conflict between the need for both higher performance and longer battery life.




big.Little can reduce power consumption by 70 percent, according to ARM. Gaming and video playback is performed on the more powerful A15 chip, while tasks that require less power, such as making a phone call, are assigned to the A7 to conserve power.


The A7 will be manufactured using a 28-nanometer process; combined with architectural improvements, this will make the processor one-fifth the size, with one-fifth the power consumption, compared with today�s Cortex A8 processor. But the A7 will still give a 50 percent performance boost compared to the A8, according to the company.


The big.Little architecture will have a die size of less than 0.5 square millimeters and draw less than 500 mill-watts of power, said Nandan Nayampally, director of marketing for the ARM processor division.


Furthermore, the A7 and the A15 will have identical features sets, so software applications will run on both cores without modification.


ARM�s designs are licensed and manufactured by companies such as Texas Instruments, Broadcom and Freescale. The chip makers are expected to produce the first A7 parts next year, and smartphone makers will begin fitting them to devices soon after that. It may take chip makers a little longer to implement the combined A7-A15 design, but ARM said this could also appear in smartphones by 2013.

Setting Up a New Hard Disk | Windows 7


Setting Up a New Hard Disk | PC Supporter



Whether you�re installing Windows on a brand new hard disk or simply adding a new disk to an existing system, it�s a good idea to consider how you want to use the new storage space before you begin creating volumes. If your goal is to set up a large space for backup or media storage, for example, you might want to devote the entire disk to a single volume. On the other hand, if your plan is to establish two or more separate volumes�perhaps one for each family member on a shared home computer, for example�decide how many gigabytes you want to assign to each partition. You can change your mind later, but it�s easiest to adjust the number of volumes on a disk and their relative sizes before you�ve put a lot of data on the platter.




Setting Up a New Hard Disk | Windows 7


Installing Windows on a New Disk



When you run the Windows 7 Setup program on a computer with a single, raw hard disk, Setup presents you with a screen identifying the disk and its size. If you want to create a single volume encompassing the entire disk, click Next to proceed . Otherwise click Drive Options (Advanced) . On the screen that follows, you can use the Size control to specify how large a volume you want to create for your Windows installation:

Installing Windows on a New Disk


If you decide not to use the entire disk for Windows, you can create additional volumes from within the Setup program. But there�s no particular need to do this. After you have installed Windows, you can use Disk Management to create one or more additional volumes in the unallocated space remaining on the disk.


 


Adding a New Disk to an Existing Windows Installation



In the graphical pane of Disk Management, a brand new hard disk, whether internal or external, appears like this:


Adding a New Disk to an Existing Windows Installation


To make this disk available for storage, you need to create one or more volumes, assign drive letters, label the volumes (if you don�t want them to be identified in Windows Explorer as simply �New Volume�), and format the new volumes. You can carry out all of these steps from within the New Simple Volume wizard.
