"how are browser requests made and the server respond"?

Answer 1

Basic HTTP Client/Server Communication
In its simplest form, the operation of HTTP involves only an HTTP client, usually a Web browser on a client machine, and an HTTP server, more commonly known as a Web server. After a TCP connection is created, the two steps in communication are as follows:

Client Request: The HTTP client sends a request message formatted according to the rules of the HTTP standard—an HTTP Request. This message specifies the resource that the client wishes to retrieve, or includes information to be provided to the server.


Server Response: The server reads and interprets the request. It takes action relevant to the request and creates an HTTP Response message, which it sends back to the client. The response message indicates whether the request was successful, and may also contain the content of the resource that the client requested, if appropriate.

Answer 2

The browser uses http protocol to connect to the server. In simple terms,

The browers calls [like a telephone call] the web servers address on port 80.
The server responds with some information about the page and then the browser requests for further pages. This goes on until the whole page is loaded.

Answer 3

The web address that you request is translated by the web servers as an IP Address. You can get to any web page by knowing it's IP address. The naming address that we all see, such as www.yahoo.com, is because of the Dynamic Naming System (DNS). This just makes connecting to other sites more user friendly and easier. I'm hoping that this is what you were asking about. If so, I recommend running a search for "Dynamic Naming System" or "DNS".

Answer 4

to get any thing from any server we (browser) need to have IP of that server. when we type any web site in address bar, a request is made to DNS server (which is default in a network, set by admin) requesting about the IP of that website. we your browser recives the IP, it sends a packet on 80 or 8080 port which is HTTP port. thus server starts responing.
