The World Wide Web was invented by a British scientist, Tim Berners-Lee in 1989 , He was working at CERN at that time.
Originally, it was developed by him to fulfill the need of automated information sharing between scientists across the world, so that they could easily share the data and results of their experiments and studies with each other.
World Wide Web is a collection of websites or web pages stored in web servers and connected to local computers through the internet. These websites contain text pages, digital images, audios, videos, etc.
Users can access the content of these sites from any part of the world over the internet using their devices such as computers, laptops, cell phones, etc.
A web page is given an online address called a Uniform Resource Locator (URL).
A particular collection of web pages that belong to a specific URL is called a website, e.g., www.facebook.com, www.google.com, etc.
So, the World Wide Web is like a huge electronic book whose pages are stored on multiple servers across the world.
Small websites store all of their WebPages on a single server, but big websites or organizations place their WebPages on different servers in different countries so that when users of a country search their site they could get the information quickly from the nearest server.
The web provides a communication platform for users to retrieve and exchange information over the internet.
Unlike a book, where we move from one page to another in a sequence, on World Wide Web we follow a web of hypertext links to visit a web page and from that web page to move to other web pages.
You need a browser, which is installed on your computer, to access the Web.
=>IRC:
IRC Stands for "Internet Relay Chat."
IRC is a service that allows people to chat with each other online. It operates on a client/server model where individuals use a client program to connect to an IRC server.
In order to join an IRC conversation, you must choose a username and a channel. Your username, also called a handle, can be whatever you want. It may include letters and numbers, but not spaces.
A channel is a specific chat group within an IRC network where users can talk to each other.
Some networks publish lists of available channels, while others require you to manually enter channel names in order to join them.
Channels always begin with a hashtag followed by a name that represents their intended chat topic, such as "#teenchat," "#politics," or "#sports".
Some IRC channels require a password while others are open to the public.
When you join a channel, the chat window will begin displaying messages people are typing. You can join the conversation by typing your own messages.
While channel members can type whatever they want, popular channels are often moderated. That means human operators or automated bots may kick people out of the channel and even ban users who post offensive remarks or spam the channel with repeated messages.
While IRC was designed as a public chat service, it supports other features such as private messaging and file transfers.
For example, you can use an IRC command (which typically begins with a forward slash "/") to request a private chat session with another user.
You can use another IRC command to send the user a file from your local system.
IRC was a popular way for users to connect online before social media became popular in the early 2000s. Today, many people still use IRC, but social media sites and apps are much more popular.
