Do you know what happens when you type a web address or URL (like www.torjtechnology.com) into your Internet Explorer browser's URL entry bar, and click "GO" or press "Enter"?
-----------------------------------------------------
Note: URL means "Uniform Resource Locator" and is the address for a resource(e.g website) on the internet. It actually represents a unique string of numbers called an Internet Protocol(IP) address e.g 164.205.65.105.
Since words/names are easier for people to remember than numbers, URLs are used to specify website addresses - while the internet server "interpretes" it to mean the "number String" address equivalent.
-----------------------------------------------------
The following describe the sequence of events that occurs:
1. Internet Explorer sends the web address(www.torjtechnology.com) to your ISP(Internet Service Provider).
2. The ISP sends "www.torjtechnology.com" to the nearest node of the Domain Name Server(i.e DNS, which is actually a set of databases shared amongst servers that stores the numeric addresses of Web sites. A new domain name e.g torjtechnology.com is added "or propagated" to these databases during the first few weeks after the domain name is registered. Only after this has been done, will it be possible to type the domain name into a browser and not get a "Page not found" error message).
3. The DNS returns the site's numeric(IP) address to your Internet Explorer(watch the status bar of your browser when next you're doing this online).
4. Your Internet Explorer sends the IP address to a router, which checks the traffic on the Internet, and finds the least busy path to the server containing the website(www.torjtechnology.com) that you've requested.
5. The server receives the IP address, acknowlegdes receiving it(your status bar may momentarily read "website found"), then places the request in a queue to wait until earlier requests(by you or others e.g when many people are trying to go to yahoo.com) have been fulfilled by the server.
6. The server then sends the website's default page(index.htm for example) back over the Internet to your ISP, which then sends it to your computer.
The process described in 1 to 6 above normally happens within seconds, even with a slow internet connection.
When you browse using a fast connection(e.g broadband/ satellite), the entire process can occur in an instant.
However, sometimes when the ISP has a problem and/or its resources are overloaded say due to many users online at the same time, prolonged access times can result.
That's when at steps 5 to 6 you find yourself waiting for what seem like prolonged periods for the webpages you requested to appear.
So, how does the above information help you?
Well, for one thing, you are now equipped to understand why this happens, when it does, so you should feel less frustrated, if at all.
Secondly, this knowledge puts you in a position to communicate more intelligently with the administator/ support staff for your Internet connection about the problem.
Thirdly, this useful knowledge puts you in a unique position to educate other internet users who experience similar problems.
