Basic Concept of Website

What is the web?

In a nutshell, the web is a whole bunch of interconnected computers talking to one another. The computers (on the web) are typically connected by phone lines, digital satellite signals, cables, and other types of data-transfer mechanisms. A ‘data-transfer mechanism’ is a nerd’s way of saying: a way to move information from point A to point B to point C and so on.
The computers that make up the web can be connected all the time (24/7), or they can be connected only periodically. The computers that are connected all the time are typically called a ‘server’. Servers are computers just like the one you’re using now to read this article, with one major difference, they have a special software installed called ‘server’ software.

What is the function of server software / programs?

 

Server software is created to ‘serve’ web pages and web sites. Basically, the server computer has a bunch of web sites loaded on it and it just waits for people (via web browsers) to request or ask for a particular page. When the browser requests a page the server sends it out.

How does the web surfer find a web site? 

 

The short answer is: by typing in the URL, or in other words, the web site address. So for example, if you wanted to find the web site www.killersites.com, you would type in the address into your web browser’s address bar or maybe use your ‘favorites’ or ‘bookmarks’ link to Killersites.
There are other ways to find web sites (like search engines,) but behind the scenes web sites are all being found by going to the web site’s official address. That brings us our last nerd detail: how does a website get an official address so that the rest of the web can find it?
