What is a VPN

VPN stands for a virtual private network, which provides an encrypted and secure connection over the internet, and restrict tracking of IP address and online activity from hackers, ISPs, and government, to provide a more private and secure internet connection.

VPNs are widely used in the corporate sector to provide secure connections to their remote workers.

Definition Of Virtual Private Network(VPN)

“A VPN (a virtual private network) is a private data network that uses public telecommunicating infrastructure (internet), maintaining privacy using encryption and, tunneling protocol and security procedures to connect users securely.”

“virtual” implies that there is no physical connection between the two networks; instead, connections routed through the internet

“private” implies that the transmitted data is kept confidential ( encryption and secured tunneling)

“network” implies communication medium using private, public, wired, wireless, internet, or any resource available

VPN stands for the virtual private network, and that is exactly what it is, it helps you create a secure private connection between your computer or device and another network over the internet.

It uses encryption and other technologies, it helps you to ensure that your internet activity is safer from hackers, cybercriminals, or snoops who may be lurking around when you use public wifi.

How Does Internet Work

When you visit a website like Facebook or Twitter, you type their domain name, this domain is basically a nickname for the websites IP address, and IP address is just like your home address only,

It consists of numbers and names since it is much easier to remember names instead of string numbers, we give websites domain names and a server translates them.

Your computer has an IP address too and so does every device browsing the internet, when you type website names in the browser,

Whether you are using google chrome, Firefox, or even internet explorer you send your data into the internet until it reaches the server, that server translates that data and transfers the websites that you have requested.

Risk On Using Internet

When you surf the internet and request for any website, you send that data to the server, you are sending them your IP address and a lot of information too, this is where hackers can intercept your information.

Imagine you are sitting in the coffee shop using their public wifi on your phone, and you wanna check your bank account, someone with the laptop can easily log in to the network and get whole of your passwords, emails, and other pieces of information you might have, but if you use a VPN the won’t be able to access that information

How Does VPN Work

When you surf the internet using a VPN connection and request for any website so first, that request goes to the VPN server and from there it goes to that website,

Then that website responds to the VPN server, and from the VPN server, it shows in our browser, so it creates an extra server between us and the website server, VPN encrypts our connection to make it more private and secure.

The easiest way to understand it is that by using encryption, a VPN builds a private “tunnel” around your internet connection, a tunnel that no one else can hack into, see into, or penetrate.

Importance Of VPN

Restrict Websites From Gathering Your Data

The websites you visit can also gather your information, but they tend to do to study their demographic, usually, it is not a problem but sometimes you want to protect your identity and privacy, so how does a VPN protect your privacy

When you send information online, a VPN creates a tunnel that encrypts your information, this way if someone gives the whole of your data, they won’t be able to read it, the tunnel also makes it harder to hack but don’t be fooled, it is still possible just much harder to do.

VPN Add an extra server

A VPN also adds in an extra server, we told about how you send your data from your computer to a server, and the internet server pings you back with the websites, but with a VPN your data goes to their server first, and then it sent out to the websites,

This extra step helps in a lot of ways, first, they can change your location, a lot of video streaming websites like Netflix, and Hulu has strict content depending on your geolocation.

Let’s say you wanna watch your favorite show on Netflix, but it is not available in your country, so you sent your information to one of the VPN servers in America, and then that server sent it to the website, Netflix now thinks that you are in America and you can stream your show without any problem

Changes Our Location

VPN tricks them to think that you are from a different location because signals are coming from different server claver right changing your location can also help book a hotel or flight,

Researches showed that hotels and flight prices change, depending on your locations, so VPN can potentially save you lots of money

VPN Secure Our Information From Government

Let’s get back to our privacy remember how we mansion, how websites sometimes collect our data well many times, the government can request this information and use the listed IP addresses to track our location,

But with the VPN your location only reaches the VPN server, and they can’t track us back to our original IP address.

Many VPNs also have a no-log policy, which means they don’t record what websites you visit, so if the government requests VPN providers for tracking log information it won’t be there.

VPNs are really handy when it comes to keeping your privacy safe on the web by changing your geolocation, encrypting your data, and ensuring your privacy, that’s why so many people are using VPN these days.
