Exposing those technology myths
We’ve all heard the
tales about how excessive cell phone use can lead to cancer or other
health problems; or how watching violent video games can make you more
aggressive. But how much truth is there to these stories? Are they based
on fact, or are they the digital equivalent of old wives’ tales?
The Online Mom takes a look at some of the top technology myths and asks True or False?
Mobile phones can interfere with airplane navigation systems
the continuing ban on the use of cell phones on most commercial
flights, “there is practically no evidence to say mobile phones pose a
risk,” says Dr. Adam Burgess, author of Cellular Phones, Public Fears and Culture of Precaution.
So why the ongoing ban? Apparently that has more to do with the
potential annoyance factor than anything else. Surveys of both
passengers and flight crews have repeatedly come down against the use of
cell phones while planes are in the air.
Macs are immune to viruses
years, one of the biggest selling points of Mac computers is that they
appear to be immune from viruses, or at least far less prone to attack
than PCs. However, it’s all a matter of market share suggests Clive
Longbottom, a director at IT analyst Quocirca: “They could (get
viruses), but with Apple’s share of the desktop computer market in the
low single digits, it hasn’t been financially viable for hackers to go
However, that is all changing. Apple’s market share
in the U.S. is now over 10% and security companies such as Kaspersky are
seeing rising demand for Mac versions of anti-virus software.
The more megapixels, the better the picture
has long been the camera industry’s basic quality equation: the more
megapixels a camera has, the better the picture it will take. This has
worked well for the camera manufacturers, allowing them to effectively
charge by the megapixel, and convince consumers that a more expensive
camera will automatically make them better photographers.
Not so, says photography expert Ken Rockwell on consumer technology web site CNET:
“Sharpness depends more on your photographic skill than the number of
megapixels, because most people’s sloppy technique or subject motion
blurs the image more than the width of a microscopic pixel.”
you are planning to blow up your picture to billboard size, a
well-taken 3-megapixel shot will look much like a 10-megapixel photo.
It is best to run your battery all the way down before you recharge it
people charge their cell phones and other high-use tech devices
overnight whether or not the battery has been drained. Does it matter?
Yes, say the experts. If you plug in a half-charged battery, some of the
components in the battery will settle and lose their ability to
recharge. If this is done repeatedly, you will end up weakening the
battery, so it holds its charge for much shorter periods.
Girls don’t play video games
the stereotype of the basement-dwelling video gamer is predominantly
male, the percentage of women playing games has steadily increased over
the past decade. Reuters reports that nearly 40 percent of gamers are
now female, and women actually outnumber men when it comes to web-based
gaming. The video game industry has recognized the importance of this
female demographic and is increasingly producing games that exclusive
Sensitive information can be recovered from your hard drive even if you have deleted it
we hit delete on our computer, those embarrassing photos and sensitive
financial files are gone forever, right? Not true, according to security
experts. Apparently, “deleting” information merely tags the hard drive
disk space as available for new data, rather than erasing the previous
data. This means that data-recovery experts – or identity thieves – can
still read “deleted” information.
However, there are programs that
can effectively “wipe” a hard drive. For Mac users, the Mac OS X
operating system has a “secure empty trash” option, which will also get
the job done.
Airport X-Ray machines can erase or damage digital memory cards
U.S. Transport Security Administration states unequivocally that “our
screening equipment will not affect digital cameras and electronic image
storage cards.” If you doubt the word of the venerable TSA (shame on
you!), then industry tests tend to back them up. In fact, compact Flash
cards and other storage cards are a lot more resilient than you think:
they can be dropped in a drink, run through a washing machine, and even
left out in the snow and they will still retain their data.
And finally, what about those health concerns surrounding the use of cell phones and aggressive behavior caused by violent video games?
Perhaps, no two areas of technology have been subjected to more debate
and more conflicting opinions. Suffice it to say that most independent
studies – including those conducted by the World Health Organization,
the U.S. Food and Drug Administration, MIT and others – have yet to find
convincing evidence that long-term exposure to either cell phones or
violent video games can have lasting adverse effects.
studies continue and the debate is clearly far from over. Perhaps it’s
safest to keep those two topics on the “technology myths” list for just a
little while longer!
