So let's start with what is a website and what is Web server?
So this is my PC and with the help of a browser, I have opened beta dot com, which is a Web site.
Now, the part which you are seeing here is called as front end.
OK, so it is basically a page estimate is a markup language.
So it is a basically XHTML page.
And every Web site you open, for example, if you open Facebook dot com, then also you will able to
see the front end part of this website.
Right.
So every Web site is divided into two main parts.
First is front end and second is backing.
Now, the part which you will able to see is called s friend or client side, and the other is backend,
which is server side.
So there are different technologies used in both front end and backend.
For example, the funding part will use HTML.
OK, and also a JavaScript.
So if you visit any anon web website and that Web site will ask you to run JavaScript, then don't allow
that Web site, OK, because JavaScript will execute on your PC and not on this server.
Right.
So if you don't trust the website, don't allow it to run JavaScript.
Now, if you talk about Beckenham, which is a server side, which is a Web server side, so Web server
is nothing but a computer like your computer.
OK, it is no different, but it has more power than your computer.
It has more memory.
It has more storage.
OK.
But the working of Observer is seen as your PC, OK?
You can also install Windows operating system on server, you can also install Mac OS, you can also
install Linux.
Right now, the technologies your server understand is BHP Billiton, MySQL, etc..
So my Ezekial is a database and.
Apache is a website, so Web server and database are two of the main components which a server must
have in order to become a Web server.
So these are the two main applications.
Any computer having these two applications has a capability to become a Web server.
Right.
So if you want to perform an attack on the server side, then you must create your attack in a language
which web server understand, like BHP Billiton, etc..
And if you want your attack to perform on the client side, then you will create that attack in JavaScript.
OK, so these are the basics of what is a website and what is a web server.
OK, now in the next lesson, I will teach you how exactly what is happening behind the scenes when
you try to access a website like Facebook dot com.
