Wi-Fi is a technology that connects your computer to an internet access point using radio signals. Also this technology is very similar to smartphones and TVs as they all use radio waves. Wi-Fi is a very important part of technology today as it allows people to connect with each other and to access information that was probably difficult to obtain before Wi-Fi. Wi-Fi is just accessing the internet like you are directly connected with an Ethernet cable however with Wi-Fi you can access the internet wirelessly as long as you are in the routers radius. Wi-Fi is a very important part of peoples live and there are many companies that make a lot of money form just selling their Wi-Fi packages such as Virgin Media and BT. Furthermore many devices can use Wi-Fi such as computers, game consoles, smartphones, cameras, tablets and many more. Wi-Fi can be less secure than direct Ethernet connection as it can be easily hacked by people, this can happen if you are using a website that you is unencrypted and if your Wi-Fi hotspot is not protected. There are now new encryptions that help protect your IP address such as WPA2. Wi-Fi can attract people to certain hotels if there is Wi-Fi there. This shows how well used Wi-Fi actually is. Many smartphones now have built in Wi-Fi to allow people to use the internet.
How is it used?
For Wi-Fi to work you need to have certain equipment such as a router and a modem. A router is what transmits the radio waves to the connected device. The router connects to a modem using an Ethernet cable and then sends waves to the technology connected to the Wi-Fi. This means that the router is the main part of Wi-Fi as it sends out the radio waves that allow you access to the internet. A router allows multiple computer...

...acked as open networks attract hackers, this has happened many times and the hacker has got hold off some personal information. Another disadvantage is the range and the limiting range as most Wi-Fi integrated devices don’t have huge ranges so you have to be in a certain range to make sure that you can access the modem/router so you can use the internet. The speed can also be slowed down by obstacles coming in the way of the router to the Wi-Fi spot and this slows the user down as the radio waves have to go through walls to reach the destination, also many other devices interfere with the radio waves such as baby monitors. One more disadvantage with Wi-Fi is that if you want fast speeds then you have to upgrade your speeds with your internet provider as the faster speed the more expensive the price however most people use the slowest speed because it is very cheap.
In conclusion, a local area network is made up of computers and a myriad of devices, such as routers, servers, switches, and firewalls. In order for it to connect to the Internet, a router must be installed. Servers provide special functions such as printing, file sharing, etc. Switches connect the computers together from different parts of the network. Firewalls prevent unauthorized access. There are a host of other devices that may be used as well. These devices are hubs, gateways, repeaters, wireless access points,
Wireless networks – While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnection between nodes is implemented without the use of wires, such as a computer network. Wireless telecommunication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” network.
Family consists of a 16-year-old African American female name, Clarice Precious Jones, who goes by Precious and is currently pregnant. She previously lived in the New York City ghetto of Harlem with her abusive and unemployed mother name Mary, who physically and mentally abuses her. She has also been raped by her father name Carl (died of AIDS) that resulted in two pregnancies. Precious and Mary are single-parents and both identity themselves as heterosexual. The family resided in Section 8 housing and survives on welfare. Her first child, "Mongo" (short for Mongoloid) is a 3-year-old who has Down Syndrome. He is being cared for by Precious' grandmother whose name is unknown, though Mary forces the family to pretend Mongo lives with her and Precious just so she can receive extra money from the government.
There is also the potential harm that comes because someone doesn’t secure their Wi-Fi. It allows unauthorized access and in some cases allows firewalls and filters which have been established for security and safety particularly for minors to be evaded and ignored. In...
A reason why Wi-Fi is the most important invention is because of safety. I can go on CNN's or NBC's website and find out about what is happening in the world, not only that, I can find out what is happening in my region. I have the ability to read about storms, such as hurricanes or blizzards that can affect me. I can also sign up for alerts that are sent right to my phone immediately warning me. In the summer there was a heavy rainstorm. Trees were falling down and it was dangerous. I received a tornado alert on my phone, because of that I knew that a tornado and power outage could take place anytime. Also, I can find shootings or fires that have happened or are happening in my neighborhood. It is much harder to be safe and alert of weather conditions without Wi-Fi.
A router is a device that connects two networks – frequently over large distances. It understands one or more protocols.
Properly secure wireless systems: - To prevent data breaches it is very important to secure wireless networks. WI- Fi network security is necessary because it is very easy to hack the data and unauthorized access. Breaches can be prevented by using strong passwords, encryption methods, and strong verification.
Education is the key to success. Many people may not agree but I’ve always believed in this slogan. It expands one's awareness and opens the door to new and better job opportunities, evolving a person successfully in life. Obtaining an Associate Degree in Nursing was the first step towards the success. It took hard work, enthusiasm, determination and devotion to become a Registered Nurse. I’m proud to say that I graduated with honors (cum laude) from Pacific Union College (PUC). Accepting an award in front of the crowd was the proudest moment for my family and I. I have looked into different programs to obtain my Bachelors of Science degree in Nursing but nothing came close to Pacific Union College. Nursing staffs devotion, encouragement and appreciation for students is what made me come back to Pacific Union College to advance into my studies.
Easy network deployment since wireless mesh network have a capability for self-configuring to ensure the data transmitted reach at the destination. This is very useful when unexpected thing happen that make the node down for unknown reason.
As evident in Table 3, Wi–Fi is the preferred means of accessing the internet in all regards except for best coverage. With the continued expansion of Wi–Fi networks, this small disadvantage could be entirely mitigated.

Wi-Fi facilitates ease of use and is getting increasingly popular with homes and businesses. Multiple Wi-Fi Access Points can be located in a given area. Wi-Fi security issues continue to be a problem, as the number of Access Points grows.
Wi-Fi (Wireless Network) or 802.11 networking is a phenomenal way of providing Internet wirelessly at a low cost. Using radio waves, a wireless network connects a PC, mobile phone or just about anything that connects to the internet wirelessly by a router. By transmitting signals at 2.4 or 5 GHz it allows the waves to transmit more data at a faster rate. Typical Wi-Fi standards are 802.11a, b, g, n, or ac and they can switch up the frequency depending on the model (Brain). Families can create their own wireless network that can be shared between family members without the use of hooking all their devices up to the modem and can also protect their home network from potential hackers with the use of a TKIP or AES encryption. Businesses can also create a “hotspot” which is an area that has wireless networks for free or at a set fee. This is extremely convenient for commuters that need internet access while they are at work, waiting on a plane, or just sitting at a coffee spot without the need for wires(Cox).
Dr. Harald Haas was coined the term Li-Fi and also promoted Li-Fi in his 2011 TED Global talk by giving demonstration of an LED bulb to transmit a video with the speed more than 10Mbps. In simple terms, Li-Fi can be thought of as a Wi-Fi based on light as it uses light instead of radio waves to transmit information. Instead of Wi-Fi modems or routers, Li-Fi uses transceiver-fitted LED lamps that can be used as a light or for transmission of the data.
Internet as part of the history is the most important invention around the world which connects people thru phones, satellites and cables. People all over the world have access to it as it is everyday usage, and internet becomes globally real and in demand. To mention here, the usage for permits technically for travelling or getting tickets are electronically through internet, paying bills, shopping thru nets without going out (just browsing), playing games, and mostly the merit of possibly downloading music and movies in no time (just a click).
