Introduction to Website

Introduction

According to a survey, an average user visits 3 - 5 websites or even more per day. This is the reason why more than 300 websites are created in a single minute. By this statistics we can assume that how websites make an influence to our life. Or, we can say that on this ground, there is a big market available nowadays. Now, several questions come to our mind like “What is a Website?”, “How it is created?” and, “How it works?” I’m going to answer them one by one. So, let’s begin.

What is a Website?

“A Website is a set of related web pages under a single domain name.” Here, by the term webpage, we want to include several multimedia content like plain text, markup language, images, audio or, any kind of information (data). “Domain Name or DNS server tells the browser about the location of the web server hosting the site.”

How a website is created?

All websites use HTML and CSS but, Content Management Systems, Blogging Software, and E-Commerce Platform often use or add a few more technologies into the mix. These technologies can be PHP, JavaScript, Java, JQuery, ASP.Net, Ruby and many more.

What we see?

When we are looking at a website, it is more likely that the browser we are using will be receiving HTML and, CSS from the web server that hosts the site. The web browser interprets the HTML and CSS code to create the page that we see.

            Most web pages also include extra content such as images, audio, video or, animation. Some sites also send JavaScript or Flash to the browser.

How the Web works?

When we visit a website, the web server hosting that site could be anywhere in the world. In order for us to find the location of the web server, our browser will first connect to a Domain Name System (DNS) server.

What happens when a web user wants to view the website which is located anywhere in the world?

When we connect to the web, we do so via an Internet Service Provider (ISP). We type a domain name or web address into our browser to visit a site for example google.com, etc. Our computer contacts DNS servers. The IP address that the DNS server returns to our computer allows the browser to contact to the web server that hosts the website that had been requested. Then, the web server sends the page requested back to our web browser.
