Well guys, what's up ???
Ehmm...Ehmm... We going to my last assingment, that is my speech.
yeahh.. Btw, my speech talk about "The Impact of Wifi Network for Human".
Allright guys, this is my speech.. Let's check it out..
--------------------------------SPEECH-------------------------------
Hearing the word of
"WIFI" I’m sure that, wifi is not unfamiliar term to you all. But, do
you know what th e understanding of wifi, how it works and the impact of wifi
network ?
In this occasion, I would share
some information of wifi. Let’s check it out.
As the title of the speech, the
impact of wifi network for human. The first before we talk about the impact, we
must know what is the wifi ?
1.
Understanding of Wifi
WiFi is a technology that uses
radio waves to provide network connectivity. Wifi is the term of Wireless
Fidelity. A WiFi connection is established using a wireless adapter
to create hotspots areas in the vicinity of a wireless router that
are connected to the network and allow users to access internet services. Once
configured, WiFi provides wireless connectivity to your devices by emitting
specific frequencies, based on the amount of data on the network.

How wifi works
Like mobile phones, a WiFi network
makes use of radio waves to transmit information across a network. The computer
should include a wireless adapter that will translate data sent into a radio
signal. This same signal will be transmitted, via an antenna, to a decoder
known as the router. Once decoded, the data will be sent to the Internet
through a wired Ethernet connection.
As the wireless network works as a two-way traffic, the data received from the internet will also pass through the router to be coded into a radio signal that will be received by the computer's wireless adapter.

The benefit of wifi
a. Global Accessibility: Wi-Fi allows
users to stay connected in a multitude of different places including the
office, home, coffee shop down the street, or hotel on the other side of the
country. Most of the electronic devices sold today are Wi-Fi capable, and the
greatest part is that Wi-Fi technology has a global standard. Unlike cell
phones, you can connect to a network anywhere in the world with a Wi-Fi enabled
device, allowing for widespread coverage.
b. Ease of Communication: Not only is
Wi-Fi convenient, but with the popularity of public wireless networks and
handheld wireless devices that support roaming, Wi-Fi allows users to stay
connected all of the time. Businesses are able to maintain a consistent flow of
communication in the office with state-of-the-art Wi-Fi technology, allowing
employees to stay connected on an almost constant basis. All of these Wi-Fi
attributes promote productivity in the workplace, as well as enhance the
ability of a company to perform at the highest possible level.
c. Cost Effective: The investment of
wireless network hardware is reasonable, especially in comparison to wired
cables that are difficult to install and manage. Wi-Fi allows businesses to
quickly install the technology anywhere in their facility and build a secure
network that can support all of their employees. Wi-Fi is easy to expand and
can take on additional users with existing equipment, unlike wired cables which
require additional wiring and installation.

The impact of wifi
a. Positive
impact
i. Globalization
As we know the function of wifi can
connected us with others, in different places or country. Just turn on the computer
and connected with the wifi, open omegle or skype you can find a new friend.
ii.Educational Games
For the gamers, to be sure that
game online is very unfamiliar for them. For the common people game online can
just find in warnet. But, not today, because if u in the café u just connected
the wifi and open the game online and u can play for free. As we know game
online, must be use English language. So that, if u play the game online u not
just playing it but, u can also add you profiency.
b. Negative
impact
i. Insomnia
Why wifi can makes us insomnia ?
because if u living in the area of wifi, to be sure that u always browsing on
internet or download movie and playing the games until midnight, and tomorrow u
will oversleep. If u still like that everyday, u will suffer from disease. Whatever
any diseases.
ii. Addiction
Well, I think this is the most
severe impact. With wifi network u can open any website, it’s like porn
website, gambling websites and drug sales. With the information I’ve got, I’ve
heard term of Deep Web. For a common people, perhaps we usually open sites like
youtube or google or facebook and others. But, deep web is different web, that
u never find on google search. Because deep web just opened by the hackers. On
deep web, u can find a lot of crime on it.
iii. Demage
a child’s brain cells
As we know, wifi using radio wave
to provide network connectivity. So that, I’ve read some article that explained
about negative impact. The World Health Organization (WHO) and the National
Toxicology Program has studied the effects of non-thermal radiation on human
health. The result is a radiation exposure that occurs can significantly
increase the risk of serious illness, especially for children. Why? Because
children have a nervous system and brain are still in the developmental
process. They have thinner skulls and smaller than the adults. This can easily
result in more radiation to penetrate deeper into their brains. Make brain
cells become damaged, causing undesirable effects such as causing headaches,
feel tired, impaired concentration and memory loss in the short term.
Closing
That’s all my speech, so I make the
conclusion as like this.
Although the use of wireless
networks such as Wi-Fi provides many advantages, such as to know the
development of the world via the internet, but we also need to be aware of the
risks when using a wifi network, whether any risk.
