Has Internet provided a lot of valuable information or caused
problems?
The philosophy of Internet, as means of providing information and
connection between different people all over the world, is one of
the noblest ideas in the twentieth century, and also one of the most
important. It is a good question, whether with the avalanche of
information, which best describes Internet nowadays, it can fulfill
its purposes.
Everyone using Internet know that it is very hard to find quickly
the right item, you are looking for. Doing this, man is wandering
trough piles and piles of useless information and the process of
looking resemble much of a fighting with a creature unfamiliar
with your desires. When I am doing a project, for example, it is
very hard for me to separate the popular information from the
scientific, and I often find that I would have finished more quickly,
if I had used the old fashion library.
Other problem of the Internet usage is that it is filled of
uncensored information as violence, terrorism or sex. This is
limiting its possibilities to be a good help to the children to
understand the world or unless the world their parents want to
show them.
Yes, the Internet is a window to the world, but our world is not so
good to view it all. I accidentally come upon this sort of
information and I am sure that it is decreasing the advantages of
the World Wide Web.
The Internet is a store of information. Some of it is valuable; other is
useless or even harmful. As humans, if we want to make the Internet
as useful as it is purposed to be, we must find some tool to navigate
through it without the difficulties, which we are experiencing now or
it will become useless.
