electronic messages

8. Inexhaustible
Education

essential propagator of
knowledge, both through free
as well as paid services. The
credibility of this form of
education and whether it is
safe, secure, and trustworthy,
is usually proven through the
quality and authenticity of
content presented by each
website.

9. Disadvantages
of the Internet
• Theft of Personal
Information
• Spamming
• Malware Threats

10. Age-inappropriate
Content
Age-inappropriate content is
perhaps the biggest
disadvantage of the Internet.
The worst being underage
material, which is largely
rampant in the deeper parts of
the web. It is the lack of
control over the distribution
and unrestricted access of
inappropriate material, that is
detrimental to children. All
that parents can do, is lock
harmful sites and monitor the
sites viewed by their children.

11. Social Isolation,
Obesity, and
Depression
The link between obesity and the
Internet is rather easy to understand.
The more one sits in front of the
computer, the lesser one exercises. At
the end of the longish list of physical
and emotional maladies, is
depression. Since all problems are so
deeply linked with one another and
with the Internet, it isn't uncommon
for people to be afflicted with multiple
issues. Recent studies and research
have gone deep enough to actually
differentiate between compulsive
Internet use and excessive Internet
use. Furthermore, thanks to
smartphones, holding a simple face-to-
face conversation seems out of the
ordinary as compared to chatting
online.
