From Web Hosting to Internet

Have you ever just sit and wondered about how a web page you are looking at can be seen so quickly with just simply typing the URL in the window and viola its there? No matter where in the world the URL’s location is it can be seen in a matter of seconds from anyone’s computer. At the most basic level of this process it all comes down to this, your computer formed a connection with a web server, requested a page and then received it.

To get into a bit more detail on how a web page can be seen on your computer screen, there are basic steps that take place behind the scenes.

-The URL is broken down into three parts which are http, the server name, and the file name.
-Your browser communicated with a name server which in turn translates it into an IP address. The IP address is what connects to server machine.
-The browser then formed a connection to the server on port 80 with the IP address.
-The browser then sends a GET request to the server asking for the specific URL.
-The server then sends over the HTML text for the specific web page to the browser.
-The browser then reads the HTML text and formats the page to your computer screen.

To understand the complete process you need to comprehend protocols, ports, and IP addresses. Continue reading through the other sections to get a complete explanation of how a web page is delivered right to your screen.

The Internet

The internet is a huge collection of many, many computers that are all linked together on a network. This network allows all the computers to communicate with each other. The home computer is connected to the internet using a cable modem, phone line, or DSL which in turn talks to an internet service provider better known as ISP. A business computer or school computer usually connects through a network interface card that directly connects to a LAN or local area network within a business. Then that business of school connects to the ISP using a high speed phone line like a T1 line.

ISP then connects to much large ISP’s. The large ISP maintains fiber optic backbones for the entire nation. These backbones are connected through fiber optic lines around the world in undersea cables and satellite links. This in essence connects every computer on the internet to every other computer on the internet.

Two Categories: Clients And Servers

Every single machine on the internet can be categorized as one of these two categories which are clients and servers. The machines that provides services like web servers are the servers. And the machines that connects to those services are consider clients. An example of this is Yahoo. Yahoo is providing a huge cluster of machines for use on the internet. Your personal computer provides no service over the internet and that makes you the client.

IP Address

Each machine on the internet is assigned an unique IP address. IP means internet protocol and the addresses are the 32 bit numbers that are considered four octets. A server has a static IP address. Static IP addresses very rarely ever change. You can typically look up any web page by its IP address. But that isn’t always feasible seeing how it would be impossible to remember numerous sets of numbers for various sites you wish to go to.

The Name Of A Domain

People can’t remember most strings of numbers associated with various web pages and in that rare instance an IP address may not remain the same. With that in mind all servers on the internet have human readable names. These names are called domain names. Domain names like is alot easier to remember than four sets of numbers that may change every once in a while. The URL there consists of three parts: the host name, the domain name, and the top level domain name.

Name Servers

A group of servers which are called DNS or also known as domain name servers maps the domain names to the IP addresses. These servers are essentially databases that put the domain names to the IP addresses which are then distributed all over the cyber world. If you type a URL ending in /web-server.htm into a browser, the browser then extracts the URL, passes it to the DNS which in turn passes back the correct IP address for the URL.

Ports And Protocols

Server machines makes its services available over the internet using numbered ports. One port for ever service available on that particular server. Clients connects to a service to a specific IP address at a specific port.

Once a client has connected to the desired service on a port, then that service is accessed through a specific protocol. A protocol is a pre defined way that a user wants to use a service talks to the service. This is how the server and client conversing begins. early cwc clients included uk betting giant ladbrokes. .
