Advantages of the Internet

• Faster Communication

• Send and receive instant electronic messages

• Abundant Information Resources

• Online Shopping

Inexhaustible Education

The Internet has become an 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.

Disadvantages of the Internet

• Theft of Personal Information

• Spamming

• Malware Threats

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.

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.
