                      R        evolution is a strong word, and one that
                               gets thrown around a lot in the tech world.
                               When used to describe a new technology,
                      it has to be something that impacts our everyday
                      lives, similar to how the introduction of television
                      made the radio irrelevant for so many years. More
                      recently, smartphones completely changed the way
                      we perceive mobile communication. Phone calls
                      and text messages are only two of the now near
                      infinite features that smartphones afford, from
                      networking to multimedia.
                          Tablets are very much on same path in
                      the portable computing space. While laptops,
  Using the tablet    notebooks and netbooks made computers smaller
                      and more portable, they didn’t quite change the

                      more like an adaptation to the changing needs of

                      are thrown out of the window in favor of multi-

                      many other technologies have received greater
                      prominence and exposure. Some new and many
                      future tablets boast 3D displays and cameras, and
                      use the latest tablet-optimized iteration of Android
                      – version 3.0 or Honeycomb. The tech world has
                      been captivated by the tablet phenomenon, but
                      whether it will revolutionize portable computing
                      or go the way of e-book readers or netbooks and

                      will tell.

                                    Apple’s iPad 2 is by far the most anticipated
                                    tablet. Apple took heed of the threat they faced

                                    year, have developed a thinner and faster tablet
                                    to follow the iPad. The biggest addition to the

old one, which keeps the iPad 2’s battery life at 10
hours.
   On the software side, the iPad 2 runs on the
new iOS 4.3, which boasts the new Home Sharing
feature. With restrictive storage at a maximum of
64 GB, syncing your iPad 2 with your media library
can be quite arduous. Apple has overcome this
obstacle with Home Sharing, which allows you to
stream media from a Mac or PC wirelessly on the
same Wi-Fi network as your iPad 2. The App Store
also contains about 60,000 apps compatible with
the iPad 2.
   The lack of a USB port and Adobe Flash sup-
port still remain the biggest drawbacks for Apple
tablets, and while the iPad 2 is already on sale in

cloud. It syncs directly to iDisk, WebDav and e-mail

the letter or report you write looks good and can
even contain embedded URLs.

    REMOTELY WIPING DATA
If your device is deemed unrecoverable, it is
advisable to wipe out critical data off your device.
Before doing that, it is advisable to back up all
your data. Start with the backup section, check
the data you wish to back up and click the ‘Backup
My Data’ button. However, it is advisable to take

that you want to delete from your device and click
the ‘Wipeout Now’ button. After you have moved
to a new device, install the WaveSecure app and
restore the backed up data.

your data; an incorrect OS or firmware update can
be just as destructive. While most of the data like
media files, contacts and settings can be easily

“The system removes smoke from the exhaust
of internal combustion engines (both diesel and
petrol) irrespective of the age of the engine or its
state of maintenance and repair. Besides removing
smoke, remarkably, it also reduces the work done
by the engine in venting the exhaust gases. This
leads to an increase in fuel efficiency by over 15%.
The device is fitted in place of the conventional
muffler. The proof of concept stage is complete
and many prototypes have been tested at the
Punjab Engineering College, Chandigarh. A patent
for the technology has been applied for and the
business now consists of developing the device
for specific engines, getting the technology certi-
fied by the appropriate certification agencies, and
selling the rights to manufacturers.”
