Let us begin the application level protocols in this lecture.
We will see the hypertext transfer protocol, that is the GDP, the hypertext transfer protocol.
Its GDP is a protocol used mainly to access data on the World Wide Web.
It is a protocol for transferring your webpages, which are designed using a language called Esteemable,
which stands for hypertext markup language.
It should be used as the services of DCB on the well-known board.
It is GDP Burgen one point one is the most common used version to its GDP works by using a user agent
to connect to a server.
The user agent could be a web browser or despite the server, must be located using the are the you
are always content its GDP colon slash slash at the start.
Its GDP is a glance through protocol by which two machines communicate using a reliable, connection
oriented transport service such as the TCP.
Its GDP can be implemented on top of any other protocol on the Internet.
The lifetime of connection corresponds to a single request response sequence to Buhr.
Its GDP server implementation reads every request as if it was a brand new request.
Its GDP pages are stored on your computer and Internet guesses.
The pages load faster, but they are stored on systems that you don't have potentially control, like
ISP caching proxies.
Its GDP server is implemented by the HDB server Microsoft, IIS, Jigsaw, Zopp and many other HTP functions
as a combination of FTB and S&P.
Although its GDP uses the services of DCB, its GDP itself, the state protocol, the client.
Initialise that lazies the transaction by sending request, the server replies back by sending a response.
Its GDP is called a stateless protocol because each command is executed independently without any knowledge
of other commands.
This is the main reason that it is difficult to implement websites that react intelligently to the user
input.
Now we will discuss the advantages and drawbacks of HDB, starting with the advantages its GDP is bad
from independent, which allows straight prospect for importing no random support required to run properly.
It can be used over firewalls, for example, global applications.
It is not connection oriented.
There is no need for network over there to create and maintain Sishen state information contending with
the drawbacks.
Integrity is not there so someone can easily alter with the content.
HDB is insecure as there is no encryption methods for it.
Therefore, it is subjective towards the man in the middle and eavesdropping on the sensitive information.
There is no authentication, so you will not have any clear idea with whom you are initiating a communication.
Authentication is send in the clear anyone who intercepts the request and can know the username and
password being used.
Now let's have a quick recap of what we learned in this lecture.
We started with the general definition of HTP.
Then we saw advantages and drawbacks of its GDP.
What we observed was its GDP has more drawbacks than advantages.
Therefore, in the next lecture, we will see the more encrypted version of its GDP is the its GDP is.
