INTERENT AND THE WORLD WIDE
WEB ARE TWO DIFFERENT THINGS
THE INTERNET
a massive network of networks, a networking infrastructure. It
connects millions of computers together globally, forming a
network in which any computer can communicate with any other
computer as long as they are both connected to the Internet.
Information that travels over the Internet does so via a variety of
languages known as protocols.
THE WORLD WIDE WEB
or simply Web, is a way of accessing information over the
medium of the Internet. It is an information-sharing model that is
built on top of the Internet.
THE WEB IS A PORTION OF THE
INTERNET
• The Web is just one of the ways that information can be
disseminated over the Internet.
• The Internet, not the Web, is also used for email, which relies on
SMTP, Usenet news groups, instant messaging and FTP.
NETWORK PROTOCOLS
THE HYPERTEXT TRANSFER PROTOCOL (HTTP)
• The Web uses the HTTP protocol to transmit data. Web services
use the Web to share information.
• Web documents also contain graphics, sounds, text and video.
THE FILE TRANSFER PROTOCOL (FTP)
• allows you to transfer copies of files between two computers
using a simple network protocol based on Internet Protocol

using FTP technology

WIRELESS NETWORK PROTOCOLS
WIRELESS NETWORK PROTOCOLS
Thanks to Wi-Fi, Bluetooth and LTE, wireless networks have
become commonplace. Network protocols designed for use on
wireless networks must support roaming mobile devices and deal
with issues such as variable data rates and network security.
NETWORK ROUTING PROTOCOLS
Routing protocols are special-purpose protocols designed
specifically for use by network routers on the Internet. A routing
protocol can identify other routers, manage the pathways (called
routes) between sources and destinations of network messages,
and make dynamic routing decisions.
THE DEEP WEB AND THE
DARK WEB
THE DEEP WEB
is the part of the Internet that isn’t necessarily malicious, but is simply
too large and/or obscure to be indexed due to the limitations of
crawling and indexing software
THE DARK WEB
is the part of the non-indexed part of the Internet (the Deep Web)
that is used by those who are purposely trying to control access
because they have a strong desire for privacy, or because what
they’re doing is illegal.

EFFECTS OF SOCIAL MEDIA
Positive Effects of Social Media
Social networks help the businesses in a variety of ways.

and print ads are completely obsolete now and demand for
thousands of dollars. However, with social media the businesses
can connect with their targeted customers for free, the only cost
is energy and time. Through Facebook, Twitter, LinkedIn or any
other social site you can lower your marketing cost to a
significant level.
The increasing popularity of social sites like Twitter, Facebook and
LinkedIn, social networks has gained attention as the most viable
communication choice for the bloggers, article writers and content
creators.
These social networking sites have opened the opportunity for all
the writers and bloggers to connect with their tech savvy clients
to share your expertise and articles. Your audience will further
share your articles, blog or expertise in their social circle which
further enhance your networks of the followers.
Social networks have removed all the communication and
interaction barriers, and now one can communicate his/her
perception and thoughts over a variety of topics. Students and
experts are able to share and communicate with like-minded
people and can ask for the input and opinion on a particular
topic.
Another positive impact of social networking sites is to unite
people on a huge platform for the achievement of some specific
objective. This is very important to bring the positive change in
society.
Negative Effects of Social Media
One of the negative effect of social media or network is it leads to
addiction. Spending countless hours on the social sites can divert
the focus and attention from a particular task. It lowers the
motivational level of the people, especially of the teenagers and
students. They mainly rely on technology and the internet instead
of learning the practical knowledge and expertise of the everyday
life.
Kids can be greatly affected by these social networking sites if
they are allowed to use them. The reason is that sometimes
people share photos on social media that contains violence and
sex, which can damage the behavior of kids and teenagers. It put
the negative impact on overall society as these kids and
teenagers involve themselves in crime related activities.
Another downside of the social media is that the user shares too
much information which may pose threats to them. Even with the
tight security settings your personal information may leak on the
social sites. Downloading your videos or pictures and copying
your status is an easy task and can be done within few clicks.
