The world has gone to the peaks of developmental progress in the vast field of science where everything seems possible. But surfing the world-wide-web is a kind of threat to your privacy.
It is as if you are exposing yourself to the entire world. Because of this particular reason and some others, VPN was created.
It has gained much popularity over the past few years, especially in countries such as China, where online bowdlerization is out of hands and sometimes irritating and scary.
But there must be a lot of questions, flooding your minds at the moment like; what exactly is a VPN? Is it necessary to use VPN? How does it work? Does VPN works without an Internet connection? What happens if we don’t use a VPN? So, let’s get through your queries one by one.
What is a VPN?
A Virtual Private Network, abbreviated as VPN, is a kind of software that enciphers your internet data and protects your privacy by hiding your IP address.
The majority of the people all around the globe do get attracted to use VPNs, either to protect their privacy or to seek unrestricted access to the internet.
A VPN gives you safe and secure access to the web by routing your connection through a central server that hides your online actions.
How Does VPN work?
Let’ see how a VPN works for its user. Firstly, you need VPN software on your device. It can be anyone from the dozen choices that are available.
After getting the software that you are comfortable with, start the VPN service from the software by switching it on.
The software ciphers your data in a different code language than what your normal internet connection provides to the servers.
This is done quickly and efficiently before the servers can detect it. The encoded data from the VPN server reaches to your online destinations.
It can be anything from your banking data to a picture that you are sharing with an online group of friends or website to a search engine.
Your online destinations view the encoded form of data coming from the VPN server and treat it in a separate way according to its changed form and its location, and not from your computer and your location.
Internet as we say is not just a connection but it is a somewhat collection of different servers that are responsible for storing websites and user’s data.
Furthermore, it works by serving the data to those whose services the user wants to use. Those servers are in contact with each other all the time. They share your data with each other to let you browse a respective page.
Usually there is no problem browsing a fun website because it does not require any of your personal or private information, so it really doesn’t matter if anyone is able to view that data.
But when it comes to online banking, money transfer, business emails, private communication, or anything else, such official matters concerning your private life are a bit more sensitive and require a whole lot of security and trust.
When a VPN service is used, your data is encoded and transferred goes in the encrypted form to your respective ISP and then to the VPN server that you are using.
The VPN server acts like a third messenger party connecting to the web on your behalf. In this way, a VPN solves the trust issues of user’s privacy and security.
Does VPN work without WiFi?
VPN servers are specifically made to protect user’s data from the Internet Monopoly, so it’s downright comical to wish for a VPN that works without the Internet.
However, considering the fact that we live in a world where everything is possible, makes the question a sensible one. And the answer is YES! You actually can get a VPN that works without Internet Connection.
This is on theory right now and a lot more is needed to achieve to actually make it possible. But as mentioned, you can get to the Internet, by using dial-up, via cell, Starbucks, or whatever. Even in times of no internet facility you might have access to Plain Old Telephone (POT).
You need to set up your own dial-up server at HQ and tell people to dial-in. They may experience a long-distance charge but this way a VPN would not even be needed because there is nothing to protect your data from, no worldwide traffic.
A dial-up connection is pretty secured already although the dial-up clients are given with some IEEE encryption. To complete the full process, “old-school” dial-in modems could be set up at your company, and the workers could easily dial in to connect to the servers.
We normally use VPNs to connect private networks across an Internet connection. But on the upper official level, in business sectors, VPNs are used to connect different enterprises. A certain company purchases some of the employees of another company.
These employees may stay in old facilities but they become the employees of the buyer. Private WAN circuits are ordered between two companies and one pair of circuits from both companies is placed at each of the working sites and VPNs are given to both according to an agreement as to the required configurations and applications.
Once VPNs are up, the traffic is limited between sites such as emails with respect to the agreement. Then it is made sure that the dynamic routing is working and it is able to reroute the traffic in case of any event of the circuits going down.
In this project, the largest time-sync is observed when ordering the circuits and negotiating the agreement as to what will be shared.
By now you must have the answer to “Does VPN work without WiFi?” VPN help to improve online privacy and provide security.
Moreover, users can surf the internet freely and bypass all types of online website restrictions imposed by the higher authorities like the government, internet service providers, or any other organization that want to block websites.
