How is a proxy server
What is a Proxy Server?
What is a proxy server? So that is the topic of this video. Now a proxy server
is a server that retrieves data out on the Internet,
such as a web page, on behalf of a user. so for example, normally when a computer
wants to view a web page out on the internet, you would just open up a web
browser and then type in the address and retrieve that web page from its web
server. Now when you go through a proxy server, the proxy server will act like a
middleman and will retrieve that web page for you. So now when you want to go
to a website, the proxy server receives the request from your computer and the
proxy server will directly retrieve the web page on your behalf and then send it
to your computer. So the question is why would you want to
use a proxy server? Well, a proxy has several benefits and one benefit is
privacy, because it allows you to surf the internet anonymously because it
hides your IP address. Because without using a proxy and when you visit a
website, your public IP address is visible so certain people can know which
websites you're visiting. But when you use a proxy, your IP address becomes
invisible because as the proxy server is retrieving the webpage for you, only the
IP address of the proxy server can be seen viewing the webpage. So your IP
address stops here and then the proxy IP does the rest of the work. And another
benefit of using a proxy server is speed. So for example, if a company uses a proxy
server and whenever a user wants to retrieve a webpage, the proxy server will
retrieve the webpage from the internet on behalf of the user and then it'll
store that web page into a centralized cache database. So if another user on a
different computer goes to a webpage that has been stored in the proxy
database, the proxy server doesn't have to go out on the internet to retrieve
the web page. It can simply retrieve it from its database and then send it to
the user. So this makes webpage retrieval much faster. And another benefit of this
is that it saves bandwidth, because a proxy server reduces the need to go out
on the internet to retrieve data because it already has that data stored in its
database. And another benefit of a proxy is activity logging. Now a lot of
companies will use a proxy to keep track of what websites their employees are
looking at. So when a company's employees are surfing the internet, the proxy will
keep a record of what websites they're visiting and how long they were on those
websites. And in addition, a company can also configure the proxy to block
certain websites to keep their employees from visiting them.
Now there's one notable thing that a proxy server can't do and that is
encrypt data as you surf the internet. And when data is not encrypted, that data
can be intercepted by hackers, ISPs, or governments with the proper equipment. So
this is where a VPN comes in. A VPN or virtual private network not only hides
your IP address, but it also encrypts the data that's being transferred between
your computer and the internet. So any activity that you do on the internet,
such as viewing web pages or transferring files, the data is encrypted
and kept private when using a VPN . And no logging is
involved. A VPN provides a dedicated secure tunnel between two points over
the internet. If you're interested in getting a VPN, I
personally use Nord VPN and if you go to NordVPN.com/powercert and
use the code 'powercert' or just click the link below, you'll get 75% off a
