Google What is 1 button
When you browse net and read various articles then you might see the Tweet, Facebook like, Stumble Upon button after the post. But at present time you may see another button with other sharing buttons. This is +1 button. The +1 button is nothing but an alternative to Facebook like button. But dont think it just like Facebook like button. It is something more than Facebook like button.
When you +1 something actually youre doing many things. Give a +1 to a post means youre recommending this post on Google Search, Sharing with your friends in your Google + Circle and most importantly youre saving the page in your +1 list.
In order to use the Google +1 button, you must have a Google Account. And the account should be visible to public. If you dont set your profile publicly visible then you will not be able to see and use +1 button.
Sometimes you may wanna save a copy of your favourite web page. But you dont need to do so if you use +1. If you see a +1 button in that web page then just give a +1 and you will find this page in your Google + profile at the +1 list!

What is Virtual Memory and Why it is Necessary
Todays computers are so powerful that users are not concerned or informed about virtual memory. Actually they dont need to! Because most of the modern computers comes with sufficient main memory or RAM. It may be 2 GB or more. And a PC with higher than 2 GB RAM hardly requires to use virtual memory.
Virtual Memory:
A minor part of your hard disk is used as Virtual memory. Generally Windows OS automatically uses some space of your installation drive (In most cases Drive C). You can change the amount of virtual memory by yourself.
If youre running a program that requires a huge amount Random Access Memory, and if your computer lacks sufficient memory, Windows uses virtual memory to run that program.
In fact, virtual memory is used to boost the capacity of RAM and to accelerate the operations of your computer. It combines the RAM with temporary space on your hard disk. When RAM is low, virtual memory transfers data from RAM to a space named Paging File. Transferring data to paging file frees up the RAM to perform its task.
The more RAM youve on your PC, the faster you can operate it. So, if your PC is slowing down due to the lack of RAM, then you should increase the amount of virtual memory by compensating a part of your installation drive. This part or virtual memory will be used by Windows as RAM.
But increasing the virtual memory is not the ultimate solution. Because it is not as fast as RAM. And your PC cant read data from hard disk as quickly as it can read from RAM. So adding RAM is a better solution.

What a Larger Screen iPhone Means for Accessibility
The general consensus is that Apple will introduce new iPhones with larger screens in a few days. With many people with disabilities using Apples flagship device for their accessibility needs a change can have a large impact on users. From a software prospective iOS 8 will offer many accessibility improvements, but hardware is also an important aspect of accessibility. The larger screen will certainly benefit some users with special needs, but may also cause problems for others.
Users with low vision may benefit the most from the larger viewing area. On current iPhones, with large text enabled, only a small amount of text is able to fit on screen. A larger screen will allow more text to fit on screen requiring less scrolling for users who prefer or require large text. The large screen will also give VoiceOver users more space to use three or four finger gestures.

On the other hand a larger screen iPhone may pose a challenge. Users with physical challenges may have a difficult time reaching all the controls. Also users who prefer using their phone in one hand and users who can only use one hand to operate their phone may find it difficult access all areas of the screen. It is possible that Apple will come up with a software solution to these possible challenges, making one handed use a breeze.
When Apple introduced the iPhone 5 it claimed that the larger screen was a perfect size for one handed, use so it will be interesting to see how the next iPhone is marketed.
People who use Apple devices as assistive devices should be excited about the companys upcoming announcement. Regardless of any hardware changes Apples iOS 8 includes unmatched accessibility features for people with a variety of needs. The potentially larger screen size will likely benefit most users. The benefits and trade-offs of larger screen phones has been explored with Android phones for years, and hopefully Apple has been able to iron out any lasting challenges. Aside from the form factor, Apple may introduce new software or hardware features that impact people with disabilities at their event. Stay tuned for information about how Apples announcements impact accessibility.
