The Tech Giant, Facebook has come up with yet another super-exciting feature known as the 'Safety Check'.

Now, what does this feature do and how is it gonna help you?

This new feature will give you a simple and easy way to tell it your friends and family that you're safe and know about their situation during the time of natural disasters.

In a facebook post, Facebook CEO Mark Zuckerberg mentioned :

'Over the last few years, there have been many disasters and crisis where people have turned to the

internet for help. Each time, we see people use Facebook

to check on their loved ones and see if they're safe. Connecting with people is always valuable, but these are the moments when it matters most'.

Now, how will it work ?

After a natural disaster, the tool will automatically get activated and facebook will determine if you are in the affected area by using the information like the city you have mentioned in your profile, your last location if you have opted in to the nearby friend's product and the city you are using the internet from .

If facebook finds that you are in the affected area, you will receive a facebook notification asking if you're safe. You can select 'I am Safe' if you are and a notification of it will go to all your friends in your friend list and it will start appearing in their News Feeds as well. In case if facebook gets your location wrong, you will get another option to mark yourself as 'Outside the affected area' and a notification of it also will go to your friends.

Similarly, you can check on your friends in the affected area and mark them as safe after they confirm it. Clicking on the notification will take you to the Safety Check bookmark where you can find all the updates of your friends.

This new exciting feature will be available globally on Android, IOS, feature phones and desktop and will be able to deal only with the natural disasters for now but definitely, its scope will be expanded over time. Hope, it proves out to be really very helpful for the people who directly or indirectly get affected by these natural disasters.

Got frustrated with the poor Wireless networks and speed ? You don't have to be anymore. The Tech Giant Samsung has declared in a recent statement that it has made a breakthrough in Wi-fi Technology and will provide the speed of 4.6 Gbps ( 575 MB per second) as against 866 Mbps ( 108 MB per second) currently available to the customers which will let them download a 1 GB file in less than 3 seconds.

The Samsung's new claim is based on the 802.11ad ( WiGig) standard which uses 60 GHz Spectrum. Until now, there have been significant challenges in commercially adopting 60 GHz Wi-fi Technology, as the millimeter waves that get used in the spectrum have weak penetration properties and are susceptible to path loss, resulting in poor signal and data performance. But Samsung has successfully achieved the highest quality by leveraging high performance modern technologies. Moreover, Samsung claims to have eradicated the problem of the interference of the signals from too many smartphones and tablets in a single room which again promises the better quality reception.

Now, talking about the downside to this : The devices from now on will be faster Wi-fi Enabled but that needs the Internet Service Providers also to boost up their network Speeds to cope up with the latest technology which can be a challenge in the path to make such a high speed available to the customers. Moreover, since the effective range for 60 GHz is just 15 feet, it wouldn't be able to penetrate through the walls and other obstacles. So, we can't say, this new technology will replace the existing wireless networks but it will supplement them by providing speedy bursts of connectivity over extremely short distances.

The head of Samsung's DMC R&D Center said in a statement that the first devices to use the 60GHz Wi-Fi Standard will appear in the first quarter of 2015 which will include Visual and Medical Devices, Telecommunications Equipment to name a few.
