Hello, everyone.
so in this video we are going to discuss about
Protocol, which is HTTP and https the
most famous and widely used
protocol by everyone of us on the internet.
So HTTP works on a port number there is
80.
HTTP stands for hypertext transfer
protocol
This is an application layer protocol as we have
already studied into the OSI layer. This is
the seventh layer protocol.
HTTP is used to connect to the web pages on the internet
whenever you try to visit any website, for
example, google.com HTTP or
https is used.
Put 80 basically expects or
waits for the web client to ask for a connection. And
this is basically how you try
to connect to any of the web client from your browser.
Once this connection has been made you will
get the privilege to connect to the World Wide Web.
Which is www and get access to
various web pages out there, which is basically nothing
the websites.
In the similar manner how HTTP works
is the same https works,
but this is in a
secure manner.
The connection of https is considered
as secure and encrypted.
So HTTP works on port number 443
the full form is hypertext transfer protocol secure
because the connection which is established between
both the parties that is client and
server is considered secure and encrypted.
So https is a secure protocol which uses?
TLS and SSL certificate to ensure
the authentication is between there between both
the client and the server.
Perfect. So let's
so as you can see.
I'm onto this website, which is Sr. Secure
dot XYZ. This is working on
https.
As you already know.
Https works on the port number that is 443.
So I'm typing the domain name and
I'm giving the port number that is colon 443 and
you will be able to see I am able to redirect to
the same website. This was https.
So let's understand HTTP. So as we can
see, this is leaderboard dot Sr. Secure dot XYZ,
which is running on HTTP and my
browser is also so showing that it is
insecure connection. It is not secure.
So let me try to connect to http using
the port number. That is 80.
As you can see I have given the port 80 and I'm
connected to http.
Also, I can directly Connect using the
protocol that is HTTP colon slash slash
leaderboard as dot Sr. Secure.xyz.
so
I hope you guys understood I can connect to http using
Port 80 and https using
Port 443 directly through
the protocol as well as the port number.
Thank you.
