In the last lecture, we had a look at peer to peer network architecture, and we also discussed the
disadvantages of peer to peer architecture, which we will be overcoming in trying to solve our architecture.
Now, let us have a look at client server architecture.
Glines, our networks are pretty much the polar opposite of peer to peer networks because in them a
single server users network operating system for managing the whole network.
So here's how it works.
Client machines request for a resource, goes to the main server, which responds by handling security
and directing the client to the desired resource.
Now this happens instead of the request going directly to the machine with the desired resource.
And it has some serious advantages.
Now, here, the server asks the central governing authority, and that is why there is ease of accessing
the files.
First, because the network is much better organized and doesn't depend on users remembering where needed
resources are, it's a whole lot easier to find the files you need because everything is stored in one
spot on that special server.
And that is why if the server is fully protected, it provides a huge amount of security to the network.
Your security also gets a lot tighter because all usernames and passwords are on that specific server,
which is never, ever used as a workstation.
You even gain scalability, client server networks can have a lot of workstations on them, and surprisingly,
with all those demands, the networks performance is actually optimized.
And therefore, less memory is needed to store the passwords.
So instead of saving the 50 usernames and passwords in all the 50 machines, we can store that only
on the servers.
And that is why most of the I.T. professionals are more concerned about the servers rather than their
hosts, because in today's services, model and business applications rely completely on client server
architecture to give the ease of information access to the customers.
I hope you understand the difference between the peer to peer network architecture and client network
architecture.
I would like to end this lecture by giving you a simple analogy, for example, if you consider you
have a group of four friends and if you want to have access, if you want to see the assignment of your
peer group, you can just ask him and he will give you his assignment.
That is no one who can say no or there is no one to keep a watch on you.
But if you have a group of four friends and teacher is there in the classroom, you can just you just
have to take the permission of the class teacher in order to do anything.
Now, this is the major difference between peer to peer networks and climbs of a network, but a central
governing authority is there to which keeps all the security measures on track.
So if you have any doubts, please feel free to ask the question and answer Butel reply you as fast
as you can.
And again, do not forget to please write a rating on review for a cause.
It really means a lot that you are enjoying this cause I will see you in the next lecture.
