Why do you need COMPUTER SECURITY?

            Computer Security is the main concern we have in today's electronic world,because today all the transactions are done online so to safeguard this transactions we have to take some preventive measures,and the manner in which you take this measures decides how much secure your computer is!!! so this blog is not on steps you should take to safeguard your online world because that point you can easily get with help of our FRIEND ,so instead I will write about why is it necessary to take this steps,and what will happen if you fail to do so.

            Your online world is always in danger,sometimes because of faulty servers,sometimes due over-excited friends who can't keep secrets and spread your details with others,and sometime due to an individual who we call as HACKER.your online world is your responsibility,you can't blame any other organization  for anyone breaking into your account it should always be our respectability to protect our virtual world .lets take an example to understand better You buy an car lets say from X company and then after some day somebody breaks into it and take away all your valuables from it,so whom are you going to blame the manufacturer who have made the car ( in our case say X company) or the distributor who have sold you the car.? let it be in that case or in our case we cant blame anyone for this as it is our duty to protect our digital world,you can't blame facebook if your facebook account is hacked into or say that facebook is very easy to hack,because as an multinational company nobody likes to tarnish their image so they try to provide us with the best security but even then your account is hacked into then it should be some mistake you would have done by giving your password or details to anyone or keeping easy to break password or keeping same password for long time or some individual brilliance i.e hacker. It is not that it is always our mistake if you are hack into,it can also be as their servers are vulnerable to attack but it is not always the for majority of case we have to protect ourself from this attacks.

           Even if you consider any company related to transactions like paypal or say ebay or any bank account ,these company have the best technology in business but as they are green pasture for hackers as once they are through they can get hold of some really big amount so along with company it is our duty also to take protection and prevent your virtual world from being misused by someone.

                 It is always as prevention is better then cure so you have to take prevention before your account is hacked into because getting back what you have lost can be virtually impossible.
you might also think as nobody till now has hacked into your account to cause you harm and will never be able to, but you should always remember that particular NOBODY wants only one chance to get hold of your account once done you will have to pay price for it,so remember ONE SINGLE ATTACK IS NEEDED BY ANYONE TO DESTROY YOUR ONLINE WORLD ,SO avoid that single attack by taking proper preventive measures.
                so along with this article I will post link from which you can help yourself to protect your online you can click HERE if you want to know about prevention against such attack and secure your virtual life.
              so friends this was the last topic for this year,thank you'll for reading it and HAPPY NEW YEAR to all .

Apple co-founder Steve Jobs is receiving a Grammy for his technological innovations in the arts.
Jobs is among a dozen people, music groups or companies receiving honourary awards February 11, the day before the Grammys. He died of cancer in October.Grammy organisers called him a ''creative visionary'' for the innovations that include the iPod, iPhone and iPad.
“He took technology and turned it into art, becoming a key player and leader in the entertainment world, particularly music, and changing the way we all use the Internet and consume music, TV, movies, books, graphics, and more,” the Recording Academy said.
Without jobs creating i-tunes the sales for albums and singles would'nt be the same and his innovations that gave the music lovers the heavenly experience.without STEVE JOBS the music industry would not have been the same his grammy is well deserved.

But why does the grammy academy always honours a man after his death?

          All latest phones have technology called as NFC (near field communication).but what is the use for this technology??specially when we have other better technologies like Bluetooth and infrared. this technology should have some more advantage or some better application then last two technologies.
so lets start
what is nfc technology ?

     Near field communication (NFC) allows for simplified transactions, data exchange, and wireless connections between two devices in proximity to each other, usually by no more than a few centimeters.

which companies were instrumental in making this technology??

Nokia has been active in this line since 2004. Along with Philips and Sony, it has founded the NFC Forum. Participation of 130 countries in this forum clearly signals that NFC is set to become a way of life in the years to come.The 140 NFC Forum members include Samsung, Nokia, Huawei, HTC, Motorola, NEC, RIM, LG, Sony Ericsson, Toshiba, AT&T, Sprint,Rogers, SK, Google, Microsoft, PayPal, Visa, Mastercard, American Express, Intel, TI, Qualcomm, and NXP.

what are the USES of NFC?

NFC can share a contact, photo, song, application, or video, or pair Bluetooth devices.
NFC can share a contact, photo, song, application, or video, or pair Bluetooth devices.
Emerging NFC standards allow users to transfer information by touching devices.
Social networking
NFC simplifies and expands social networking options:
  • File Sharing: Tap one NFC device to another to instantly share a contact, photo, song, application, video, or website link.
  • Electronic business card: Tap one NFC device to another to instantly share electronic business cards or resumes.
  • Electronic money: To pay a friend, you could tap the devices and enter the amount of the payment.
  • Mobile gaming: Tap one NFC device to another to enter a multiplayer game.
  • Friend-to-friend: You could touch NFC devices together to Facebook friend each other or share a resume or to "check-in" at a location.
  • Bluetooth and WiFi Connections
NFC can be used to initiate higher speed wireless connections for expanded content sharing.
  • Bluetooth: Instant Bluetooth Pairing can save searching, waiting, and entering codes. Touch the NFC devices together for instant pairing.
  • WiFi: Instant WiFi Configuration can configure a device to a WiFi network automatically. Tap an NFC device to an NFC enabled router.

                NFC expands eCommerce opportunities, increases transaction speed and accuracy, while reducing staffing requirements. A Personal identification number (PIN) is usually only required for payments over $100 (in Australia) and £15 (in UK).
Mobile payment: An NFC device may make a payment like a credit card by touching a payment terminal at checkout or a vending machine when a PIN is entered.
PayPal: PayPal may start a commercial NFC service in the second half of 2011.
Google Wallet is an Android app that stores virtual versions of your credit cards for use at checkout when a PIN is used.
Ticketing: Tap an NFC device to purchase rail, metro, airline, movie, concert, or event tickets. A PIN is required.
Boarding pass: A NFC device may act as a boarding pass, reducing check-in delays and staffing requirements.
Point of Sale: Tap an SmartPoster tag to see information, listen to an audio clip, watch a video, or see a movie trailer.

Identity documents
         NFC's short range helps keep encrypted identity documents private.
ID card: An NFC enabled device can also act as an encrypted student, employee, or personal ID card or medical ID card.
Keycard: An NFC enabled device may serve as car, house, and office keys.
Rental Car and hotel keys: NFC rental car or hotel room keys may allow fast VIP check-in and reduce staffing requirements.

what are the Technical specifications of NFC technology?

         NFC is a set of short-range wireless technologies, typically requiring a distance of 4 cm or less. NFC operates at 13.56 MHz on ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to 424 kbit/s. NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target. This enables NFC targets to take very simple form factors such as tags, stickers, key fobs, or cards that do not require batteries. NFC peer-to-peer communication is possible, provided both devices are powered.

      SO with that lets finish topic for todays blog,which is NFC technology its uses what is it,what are it differences from bluetooth. but we can be assured that this technology won't come to India soon it will take some more time then rest of world but we can be assured that it will take its own time to be noticed in India,not because people in India are not capable of using it but due to laidback nature of Indian people, to not use all the technological resources to to its optimum.
