If you are a celebrity, you are vulnerable to hack

If you are a celebrity, you are vulnerable to hack

No doubt that celebrities are more talented , good looking and intelligent than us but they are damn vulnerable to hack.For example, lets take the Oscar winner Jennifer Lawrence , recently whose’ extremely private photos were leaked by hackers from the Apple’s cloud storage service. Celebrities are being targeted because their private data are extremely valuable in the underground markets as well as many hackers try to show their skills to the world.

Why Celebrities are vulnerable to hack?That’s what this topic is about. When we forget our password of some websites we try to recover them from the ‘forget Password’ option, and there we have two or three option two reset or retrieve our password , first by receiving a password rest link in our email id, secondly we have to enter the ‘one time password’ received on our cellphone else we have to answer the security questions.Skip the first two options and lets try to answer the security questions.  Most of the account’s security questions based on the followings :

• The place where you were`
• In which year you were born?
• Your childhood nickname ?
• Which High school did you attend?
• Your Childhood best friend name?
• Your birth year?

If you are a celebrity or a popular person then all the answers of the security questions are already out there around the internet . Turn on the Wikipedia pages you will get all the biographical information from the birth year to yearly life story.A celebrity has to face different questions which belongs to their personal life, likes dislikes, hobbies as well as career . Hit the search engines and it will retrieve all the information published on the online portal of news and entertainment channels .   Their social profiles also yells various internal information about their daily life activities which can be the key of the security questions.

Well, nothing is secured in internet but one should adopt latest security features which are availe by their service provider such as Dual authentication systems , fingerprint recognition system etc so that a hacker have to access the celebrity’s device or have to plant malware to see the one time password which is not impossible but a difficult task.

Story of cloud storage security

Story of cloud storage security

By Kajal Majhi   1:21 PM   No comments:

The recent phenomenon of compromising the cloud account of Hollywood stars and leaking their private pictures around the internet , has been the hottest topic from last few days. As this incident has tickled the medulla of website moderators , security analytics and cloud service provider  that what to do. Really it is a million dollar question “What to do? “   Because it is the matter about security and privacy of the users.

Yes we can do a lot of things , but there is an one strong point which everyone should know. “Nothing is 100% secured in the internet”  Not mine, not yours and nor even the geeks who designs security protocols .  Internet is the game of codes, hardware, connectivity and we users . The things we human knows to build , does also know to break it, If it is not possible by punctual manner then there are lots of hammering and destructive way to break it.

Understanding the cloud storage

Cloud storage service has been built to bring flexibility of data sharing and migration anytime and anywhere. Once you upload your data then you can retrieve it from anywhere in the world. You don’t have to carry your own storage device , you just need an computing device with an internet connectivity .

So, here I have a question, where does you upload your files?

Sorry, don’t get me wrong,  but I have to say this.  Point to the line above “you don’t have to carry your own storage device” . So you are uploading your data to someone else’ storage media isn’t it? Where you don’t have any idea and control other than accessing your files and configuring your account’s digital security.  You don’t know where the storage media is,  about the physical security in the data warehouse of cloud service provider and so on. Its like handing over your important things to someone else.

Is your cloud account secured?

Keeping the point in mind “Nothing is secured in the internet” . But there are lots of way by which we can prevent or extend the duration to crack the security . Almost every cloud service provider has multiple security option some of them are by default and few of them have to configure by the user itself.

Two step authentication is one of the most important security measures that should be adopted by everyone , for not only your could account but also for your email and social accounts. In dual step authentication , first you have to enter your primary password and then the server will send you a text with a code, that’s your secondary password.

Authenticate by generating code using your smartphones cloud apps.

Pincode : It is generally generated once during enabling this feature. You will need to remember this incase you have enabled dual step authentication but you don’t have your cellphone with you.

Security question : Never choose an security question and answer which are know by anyone other than you.

Enable the SSL encryption.  Many cloud service has SSL by default and few have to configure by the user itself that he wants SSL encryption or not.

Secure your computer first

What is your primary computing device? Your laptop, desktop, tablet, iPad, or smartphone?  Do a proper maintenance of your device on a regular basis. Don’t keep the unusual applications and programs as it may bring security flaws.  Use a total security program consist of anti virus, anti malware, firewall , spam/phishing detection system etc. Do the updates of your operating system once in a month to get security patches .

Apart from these, spend your little more precious time over internet to learn about worms, malware, virus and information security threats . It will help you to deal with daily life phenomenon.

How is your smartphone?

Smartphone is one of the most important daily life gadgets , without it we feel like we are out of this living world isn’t it?  Yes it is,  it has more secret information than your social id does and can be the target for your competitors and malicious hackers.  Never Jailbreak or root your smartphone if you want to keep it safe. Root and Jailbreak can break the security level of your smartphone and becomes vulnerable to information security threats.  Keep a security program in your smartphone , by which you can wife the storage remotely if you ever lose it.

Few lines from my opinion.

Cloud storage is great innovation and technology for this developing IT infrastructure of this world. You can backup your data for emergency purpose, you can share work and office documents with clients and workmates , and much more. But I don’t recommend it keep your extreme private data on cloud storage as cloud storage device are not managed by yourself . If it’s the matter for your extreme privacy and security then there is no safer storage device  in the world other than your own isolated hard drive.

Did you get bored? Sorry about this :)  please express your anger by dropping your comment below :)

My dream phone a real smart

My dream phone a real smart

By Kajal Majhi   12:32 PM   1 comment:

If it is possible to grab the world in my hand , use the technology to most then  I will use my smartphone to do that. In the modern era of high end technologies we have reached much ahead that we may not have imagined a decade back . An innovative trend of the product of technologies is smartphone , in which we carry our world, connectivity, accessibility , entertainment and captures in our pocket.
I wish If I can enhance the power and features then it can do what others can not do and It will really change the way of our daily life activities. Smartphone are something on which we are very much dependent like accessing the internet when we are away from computer , enjoying movies , sports and other videos when we don’t have a television by our side, a handy tools to click pictures, and so on, and if we combine more features within it something which is really innovative. Read my wish list that I want to combine all these to form a real smartphone and with which the stuffs that I can do and others can’t’ . Follow me :

Artificial Intelligence

Call it Artificial Brain. In the smart world everyone want their device to work smartly , effectively and efficiently . I want my smartphone to have an Artificial Intelligence system or artificial brain that will work like machine and act like human.  It will have pre installed initial features and programs but it will also learn to stimulate with users , from interaction of humans like a small grown baby then each and every day it will learn something new and its’ functions will increase may be limit to infinity.  The ability to learn, think analytical and react according to changing condition will really bring blaze in smartphone and computing.
For example, if someone is calling and the user(receiver) is not near by the device then the device will receive the call itself and talk like its user and save the conversation for him/her.
If  I want to write something , I don’t have to speak loudly or type , I can just move my lips and I will detect what I want to speak.  Or it will detect the words just by moving my fingers on air from a distance etc and so on.

Smart processor
Obviously a smart device needs a very smart and powerful

processor that can handle high end task effectively and efficiently without any hindrance . A smart processor which is going to work with artificial brain should be biologically inspired  modelled like real life neurons which is capable of learning from the feedback of users. It should be fast enough to do multiple task at a same time at the same speed.
One common issue for smartphone processor is extreme usage of battery,  but the smart processor will consume very less power and conserve the rest for rest of the process in the device as well as the device will be enabled with multi source of power such as it will absorbe power from geothermal  heat, heat emitting from human body  and solar energy in such way that If it is consuming one source of energy it will automatically charge it’s battery cell from secondary and tertiary source of energy so that I do not have to worry about losing or charging my smartphone.

Smart display screen with holographic interface 

Indeed a smartphone without a smart screen is incomplete since touchscreen has replaced the traditional approach of input now it screen is only the primary output and input device for smartphones. We can enhance it more by including a holographic input and output. Holographic display will give more impressive output , explore into more depth  of the things, as well as diaphragmatic view will express more of the content beautifully  for high tech gaming  The interface will be much better, one need not have to use the small touch screen anymore to type , draw slide and zoom,  with the holographic interface one can change the resolution size of the interface according to his/her preference which will stand as much better and user-friendly input method .  We can move the images around, push them right onto the table, interact with the area above table and do many other manipulation using see-through and reach-through mist screen.one can have many screen instead have single small screen with minimal display.

Accessibility, Connectivity and security.
The internet has already minimized the distance between the people and countries ,  and no doubt there will be much improved and advance connectivity within next few years and compiling these advance network features with such smart device there will be much  connectivity and accessibility to our online world. We can explore much better , we can build a much secure access by the security and defence system of artificial intelligence , as it know what is harmful and what is beneficial for your device , it knows what is your confidential data.

One in all

We prefer laptop instead of desktop for portability, tablets and pads instead of laptop , we prefer more in portability, so why not all in just one small handy device ? if it has a powerful processor , artificial intelligence , holographic input and output , connectivity, accessibility then it is possible to have feature of advance computing and heavy tasking like we do in our desktop or laptop.  The processor and artificial intelligence will do the real tough job of computer, holographic interface will be the primary means of input and output ,  connectivity which will connect the device to world in all means , and the intelligence security will provide smart a authentication and accessibility as It know the human behaviour  it will provide much better defence from hackers and spammers .

So I don’t need to buy a big damn computer for normal desk job, I can easily create presentation,  edit multimedia files , computer added design ,text  documents from just a small handy smartphone laying on bed. Isn’t good?  Imagine the capabilities of a smartphone with these features , It will create dynamic change in computing ,  network and communication  .

Power of cloud computing

Power of cloud computing

By Kajal Majhi   5:10 PM   No comments:

Technologies has pulled the world into a modern era , where internet has become our primary source to connect around the globe. From last two decades internet has played a vital role to pull the mode of communication, data transfer and work in the most advance way as it possible.

You know, we have fully adopted the technologies for our daily life, and when our life changes then the mode of our requirement changes too. The emergence of new generation computers, smartphones, tablets has brought an evolution in computing and world wide web.  I think you are already using the cloud computing service if you are using web based mail services such as Hotmail, Gmail, Yahoo Mail etc, through which you can access the email services from any device having a internet connectivity and from anywhere in the world.

So, What is cloud computing?

Cloud computing is delivery of computer resources over internet rather than storing those resources in our own personal computers. Cloud service allows us to use the software and hardware resources that are managed by third parties (cloud service provider) at remote location.  We can use the cloud computing service over internet from any location. We can retrieve our data and information from anywhere in the world being connected with cloud service.

Imagine you are running a company where each and every employee need a computer system and some software installed in their allocated system and who have to purchase licenses for those software. If you manage your own centralized database for your company then , you need system administrators , high storage space, server maintenance ,system cooler,  security, uninterrupted power supply and so on. If there is a new updates in the server’s  software & system then the entire system workstations will go down until they don’t get supportive update packages. 

You are already using some cloud computing services such Gmail, Yahoo mail, Hotmail, Facebook,  online file hosting service etc, do you need any updates? Do you need to run them by burning your own electricity? Do you have a technical team to keep on eyes on these? Do you need security enhancement every month? Its NO, all it gets automatically and you don’t have to worry about anything. That’s the pros features of cloud computing.

So, what if instead of running your own system and servers , let the third party company host the applications, storage spaces , hardware and other services for you, then  you don’t  have to worry about security, upgrades & updates, technical team etc., you have to pay only for those things you will use as a monthly subscriptions, no extra charges, no maintenance and upgrade expenditures , you will receive upgrades automatically . The only thing you and your employees will need is a cloud computing interactive software , just log in and get started.
The cloud computing have almost every services from commercial apps, business apps, online  business and marketing systems , live collaboration system and much more. You can even demand a service from you cloud service providers.

The Power of cloud

I am in love with cloud computing because of its extensive features, the live collaborating system is amazing , especially when I am doing online study, its helps me to interact with my fellow mates and mentors   with hands on coding , sharing  and editing the same data at a once .
I feel   proud  that, I have achieved the certification of  Certified Android Developer and Certified HTML5 Developer through online mode and practicals on cloud platform. Its fun when more than one people work on the same file, its makes me feel more than a class room.

The cloud storage, where I keep my personal data as backup,  I had to face hard disk crashes, lost my smartphone , but cloud storage helped me to come out of those depression , where I feel my data are safe, I can access my data from anywhere whenever I need, I don’t need to carry a giant laptop or hard disk where it is unsafe , only an internet connection and a small device can retrieve my all the data I need.
There are some business and word processing apps are freely available at some cloud service , I use them which cut the cost of purchasing those software for my computer .

NOTE (the privacy policy):
The biggest concern about cloud computing is the privacy  policy because in this system we handle over our personal/commercial data to another companies. It is necessary to read the ‘privacy policy’ of the company whose’ cloud service you are going to use. There are few more things that you should be concern  such as, does the company who claims to provide cloud storage space actually own it? Does the company has enough data security system to protect the clients’ data? Does the company has enough physical security for the data warehouse? And much more.

How to protect identity theft in online banking

How to protect identity theft in online banking

By Kajal Majhi   5:39 PM   No comments:

Online banking system has made our life easy and trouble free from daily hassle and save a lots of time as everything is a click ahead, but no doubt that there are lots of bad people around us due to which there is a possibilities of our account being hijacked or theft of our identity & banking information. 

Malicious people/hacker are always looking for  your personal information like bank login data such as id and password,  credit card numbers, social security numbers  etc. They will attempt various methods like by sending malicious email, backdoored software, fake call etc   to gain access  in your bank account. So when it comes about the matter of online financial transaction, we always need to be precautious.   You should follow the following steps to keep your account secured.

Secure Websites | Secured Browsing

If you need to send & receive confidential  like banking and company’s secret  data through a website, first make sure that the website is secured . Now a days almost every banking websites  and other important websites  have  secured socket layer , through which we can send the information to the server in encrypted format rather than in plain text. It will protect the sensitive data from being sniffed. To be sure the website is secured or not, look at the left of the address bar, if it is secured the address bar will have https protocol with green text and an icon of lock.

Malicious Website | Cloned/Phished Websites

As I told above an important website must be secured over SSL , the malicious people may try to fool you by redirecting you to the fake websites that’s look like the real one. But a fake website will not have a SSL certificate or https encryption . So make sure that the security of the site is well configured and never ever click on any link send to you by other people says that it’s a banking website.  If you can’t conform yourself that the website is real of fake, then Google & Wikipedia is always there for your service.
You need some configuration in your browser too. In the cookie settings never set it to “Accept all cookies” , turn on the “Phishing filters” and also turn on the  “pop up blocker”

Malicious Email | Pop up message

If you receive any suspicious email saying that you have won a grand prize and your email id is in their random list, don’t give any response to these types of emails. Such emails are the traps to collect your personal information like banking  and other data .  Sometime pop up ads on website displays something greedy like You have won a IPhone,  you are their lucky winner and blah blah , don’t click on such ads. Go to your  browser settings and turn on the pop up blocker.

Fake Call | Social Engineering

If you receive any call  and says anything like this call is for security purpose and they need your bank account details like credit card number, log in id & passwords to verify your identity, Beware of such calls! It’s  a to hack into your mind and collect your personal data. Banks will never call you in such way, if banks have any security upgrading you will receive a postal letter from your bank or they will call you to visit the bank for confidential work.

Bank Statements | Credit card statements.
Kindly verify the bank statements personally from bank, if you see any unusual charges or transactions.

Malicious Software | backdoor
Beware of free software and email attachments which may contains malware and keylogger that may infect your system and record your every online activities , collects the important sensitive data and sends the information to the attacker. Use a good anti-spyware & antivirus to protect your system from unusual software. Antivirus and antispyware needs regular updates ,

Cyber security & it’s awareness is the need of the hour. In this modern world most of the people know how to use the internet but, most of the people don’t know about the online threats & how to secure the internet.  Everyone should be aware about the online threats .As the technology is progressing, we are getting more dependent on them to make our life easier by the online ways  of daily life stuffs. Let it be socializing at Facebook, online business deals & presentation, cloud storage, paying bills online, making reservations or sending  private emails etc. everywhere we need extreme privacy, authenticity , security & confidentiality . 

 But there are many threats around the internet such as information warfare, cyber terrorism, malware,  violation of data integrity, phishing, Disturbed Denial interruption of service and so on, by which the malicious hackers try to steal  private data, high sensitivity business information , and much more. They even collect our personal information and sell them to the other people for huge price of money. People who are not aware of these things can be easily a victims of such incidents.
Here I have some basic security tips for everyone that can be helpful to avoid such threats in our daily life activities.

PASSWORD:Don’t use the same password in every websites, because if a website’s security is compromised then a malicious hacker can have access to all your data, he/she will may use your LOGIN data at many other websites  to get access, If you have used the same password and user ID the hacker will gain access automatically.
Always use a unique & strong password that the word should not exist in any dictionary , consists of capital letters, small letters, numbers and special characters .example: ‘Xs&5@a3zt! M’

TWO FACTOR AUTHENTICATION : It means authenticating in two steps, in this feature you have to prove yourself twice that you are the real one, first by entering your user id & password , then in the second step you will receive a code in your cell phone which you have to enter in the website. It helps more to protect your account from unauthorized access in your absence.  Almost in every daily usage websites such as Google, Apple, DropBox, Microsoft, LinkedIn, Facebook, Twitter has this feature.

SYSTEM SECURITY: Use a good firewall & antivirus in your computer, update them regularly to protect your system from virus, worms & network attacks.  Stay away from junk software that’s says to make your system run faster, cracks & hacks of software & accounts. These type of software are mainly backdoors & key-loggers  that records your keystroke, interrupts in the normal process  and lead to  vulnerability of system .

HTTPS SECURED SURFING:  If you attempt to do any financial transaction online like online shopping, paying bills and online banking etc, always use https:// instead of http:// . The https protocol sends the information to the server over secured socket layer rather than in plain text. It will protect your financial data from being sniffed by malicious hackers.

 SMARTPHONE PROTECTION:  Smartphone has brought the world into our fingertips, It allow us to communicate , navigate, connect the internet, shoot the pictures and much more, that means we have thousands of data in our smartphone, data like contact numbers, personals images, email id, record of instant messages & much more. Now a days Govt. & some malicious hackers targeting the smartphones users for surveillance & to collect data. So beware of everything what you use, what you install from outside, with whom you share. Don’t install junky apps which are for fun & entertainment , because they are spam and backdoored  and can harm your phone.  Install apps from only the trusted apps market . And always notice what type of permission does the apps seeks
, for example an app for playing video will never require to access your contact book, if any apps ask you to permit for any unnecessary access , then it is for sure that the app is spam/malware/backdoor.

SOCIAL NETWORKING: Social networking is our another world where we spend most of the time than eating , sleeping & studying. According to recent survey of Indian Cyber Cell, about 40% of crimes against women originate from social networking websites.  It is an important place where we add strangers and make them our friends, we share images & videos with them , we chat for countless  hours without knowing much about them , so here we need  extreme security & privacy.
Before adding anyone into your friends circle make sure that the profile is legit and belongs to the actual person as it is named, check his/her profile updates that there is not any offensive contents. Change the accessibility mode of you photo albums & updates only to friends or  with the people only with whom you want to share. Hide your address & keep your contact number private, that means only viewable to you. If you see any fake profile or someone is bothering you then block them & contact the website’s help centre.

PREVENT IDENTITY THEFT: Hackers are all around, they can retrieve a lot of information about you, network connection &  your device just by your IP address (Internet Protocol).With the retrieved information the hackers can easily try to get access into your device , even they can mask their IP with your IP address.   If you are doing very confidential work and sending very sensitive data over the internet then you must hide the real identity of your device, by using secured proxy servers , or setting up own virtual proxy network or by using tor browser which hides your real identity.

BEWARE OF PHISHING: Phished website are cloned pages of original website, they looks almost real like the original website but these pages are trap to collect the User ID, Email id & passwords. Remember, any legit website doesn’t ask about the details of your email account.  For example, Gmail id & password, Facebook user Id & password etc. If any website ask you to enter these, then  no doubt that it is a fake/phished page.

INTERNET COOKIES :  Cookie is a small file that is generated from web server & placed in the user hard disk for the user identification. Malicious hackers can steal your cookie & hijack the season between you and webserver . If you use public computers at office, college, cyber café or somewhere else, then clean the cookies after use. You can do it by going into the browser settings.

“Remember, nothing is fully secured in this world, everything is breakable, we can only apply some tricks  and methods that will take time to break which is enough to aware ourselves  .”

what is two step Authentication

what is two step Authentication

By Kajal Majhi   10:05 PM   No comments:

Most of us know how to use the internet but most of us don’t know how to secure the internet.
In this cyber world, security is very essential,  because most of our daily life activities from sending personal and business E-mails , banking transactions , to our virtual world of social networking  are done online.
Having online security doesn't mean only for your online bank account, it is also for your  email account, social networking  website such as Facebook, twitter  etc. Because everyone is associated with each other directly or indirectly and among which your email account is the main key to every websites. Well..

 What is two Step Authentication ?
 Authentication is verifying your identity to the system by entering your  user id , password  and gain access to use the services of the system.  Where as to ensure more security, two step verification is verifying your identity in two steps. First step is by entering your User ID/Email ID and password, then second step is  verifying by something  that you always keep with you that proves that you are the real one. So in second step you always need your cell phone , in which the website will send you a code and you just need to enter the code and get full access.

I know it’s a bit of lengthy process as you have to keep your cell phone always with you and wait for a minute every time you try to log in and its makes you feel painful, because in the E-world we want everything quick and easy , but these things doesn't matter if you want to secure your online assets .

Imagine your friends know your Email ID and Password , and he want to access your account in your absence to spy on your personal feeds, then what? He will enter your first authentication data correctly but he will stuck at the second step when the system will ask him to enter the code that has been sent to your cell phone. Isn't helpful?

Most of our primary usage website have two step authentication system, like in Google, Facebook, twitter, LinkedIn, Microsoft, Apple , DropBox etc.

How to Set two step Authentication 

Lets start with Google account.
Just  goto your Google account at http://accounts.google.com then move to ‘security’ section and enable “2 step  verification”. All you need is your cell phone number , if its not verified then kindly verify it. All the options are there.

DropBox  2 step authentication
No doubt that dropbox is an important website for cloud storage for personal or commercial purpose and it needs security indeed, It also supports authentication by SMS . You can set the 2 step process from your account settings and then move to security section. Whenever you will use a new device you need the SMS code to gain full access into your account.

Twitter ‘Two factor verification’
Twitter call this process ‘two factor verification’ . You need a verified phone number to get started. Go to your twitter account settings , Select ‘required a verification code when I sign in’ then click on add phone and follow prompts. You will receive a six digit code whenever you try to log in.

Microsoft
They lunched this system recently and obviously  people need this in their Microsoft account because with only one account it gives the access to Xbox, Outlook, Hotmail, Dreamsparks, SkyPe and I don’t know how much more . To enable this system goto account settings move to “Security Info”  then click on “set up two step verification”

Facebook Login Approvals:
Facebook supports  code generated only from their own mobile apps. Offline . Go to your security settings , edit the ‘code generator’ .
You can enable the apps. Password to use a special password every time you use the Facebook mobile apps from your cellphone.

Review of Windows 8

Review of Windows 8

By Kajal Majhi   11:07 AM   No comments:

Windows 8 review, see what changes microsoft has made in this new generation operating system. you can directly download windows 8 from here 

Installation is quite similar and smooth like Windows 7. The first screen looks like modern web interfeace.The 1st step is to give name to your system as like all operating system after that creation and name of user accounts. Then windows 8 moves towards web ,you need to login through your windows live ID if you don't have you have to create. You can also skip this login process.

You know what windows 7 has bright blue colour screen but windows 8 have plesant green screen which will not effect yours eyes so much.

Now the time comes for confusion!! when you will click on the start bar you will think list of programs will be displayed but nope! :) you have to click on start then click on search to find all the application. And its build in conference , it means start typing something and application searching will start, to run any application, suppose to run comand prompt just type "cmd" and hit enter. isnt cool nad time saving?

Windows 8 have two types of application Metro applications made up with javascript and HTML5, and other of old software.

Now another intresting the windows 8 applications does not contain close button!! damm!then how will you close the application??
Here you go, Windows 8 use apple iOS method of program management, in which the application keep running in background and determines the usage.When the application is not in use, it close automatically.

The task manager of windows 8 contains the list of programms which is running, it is a cpmpletely redesgned task manager looks like more powerful than windows 7.

Know what? windows 8 really knows how to copy files :) in windows 7 the average speed of copying files was 25mb/s , now in windows 8, its amazing 80 mb/s, you can also pause copying files and later you can resume after completing heavy task.

Ok buddies, here you go for the summery
Good news!! 
1. New metro style interfeace
2. green screen.
3. Applications have more appealing and clean designes.
4. If you log in to your windows live id, your settings and themes will be sync, no fear of loss.
5. Just type the name of application and it will start searching.
6. New designed and powerful task manager.
7. Knows how to copy files faster :)
8. Faster boot 6 to 8 seconds

The sad news :( :( umm 
1. No easy way to close application. This might engage the computer's memory.
2. lack of all programs.

If i had left something, then people please inform me, I will add.

3G for games 4g for cops

3G for games 4g for cops

By Kajal Majhi   12:31 PM   No comments:

Hey people of India get ready for the taste of 4G.

What is 4G?
The next generation of wireless communication system after 2g and 3g based on LTE(Long term evolution).It enables high speed wireless or mobile broadband access.

What you can do with 4G?
Play interactive games, download and watch movies, download and upload high definition videos in real times. Watch HD Television, conduct HD video conferences on any mobile devices.

But wasn't supported 3g supposed to do all that?
4G is faster and more reliable.Theoretical speeds for 4G range between 100 MBPS and IGBPS(1 gigabites per second). Actual speed could be lower.Latency is down to 10-15 millions.In 3G theoritical speeds ranges between 384 KBPS and 5 MBPS.Latency is 45 milliseconds.

Who will offer 4G?
Reliance Industries, BSNL, Aircel, Tikona digital Networks, Airtel, Qualcomm, MTNL, and Aurgere Wireless Broadband India,

What you will need.....
You need a 4G or LTE Dongle , customer premise equipment, smartphone or tablet.

According to telegraph India, 3G and 4G both will exist because they will have different usage profiles. 3g will be used for more popular offerings on handsets, chatting, games, accessing the internet and so on. 4G will be preferred by small and medium business, police or radio cab networks or people who carry the work
around.

I can't believe this that yet 3g is not available every where in India and there buggers are talking about 4G? whats say people??
