Web Page
Web Page is a structured platform of medias such as Music, video, texts and scripts and style sheets in a proper way to browse using browsers. These are basically written in Hyper Text Markup
Language(HTML).

Web Browser

Picture explanation of how Web Server Works
When web pages are stored in Web Server then any internet users can access it.

Website
Collection of webpages in a connectivity of contents. It can be accessed by browsers. A virtual location on World Wide Web.

How it Works...????
Computers will easily understand Binary languages, but Human uses languages to communicate. So,URL of every websites are assigned to a certain IP address. These IP address are found from DNS Server.
The following is the step How website is shown in Browsers...?? 
When a user opens the browser and enters the URL (Uniform Resource Locator) the browser will ask the DNS (Domain Name System) server for the IP (Internet Protocol) address of the webpage.

Now the IP address will be given to browser and then browser will request the website's server to access a copy of website.

 The server will allow it to use and sends Data packs of HTML streaming. The webpages will load some time according to the HTML structure and the requested website is shown.

Some types of Protocols and their Uses

There are so many editors available to do HTML practice and developments. Normally in Windows OS Notepad is used.

Intro to Atom :  To do advanced development Atom software is used. Its an open source IDE (Integrated Development Environment ). Its a very easy IDE to develop HTML projects. It was developed by Github site,...

   HTML Sample
