    ARPANET used a clever system called  packet  switching. Instead of sending information as
                     one big piece, it broke the data into smaller pieces called packets. These packets would travel
                     through different paths and then be put back together at their destination. This made ARPANET

                     faster and more reliable.
                     Although ARPANET was shut down in 1990, it had already inspired the creation of the Internet.
                     Today, the Internet is much bigger and faster, but it still works on many of the same ideas
                     ARPANET introduced.

                           HTTP

                     HTTP stands for HyperText Transfer Protocol. It is a set of rules
                     that allows computers to communicate with each other over the
                     Internet. Every time you visit a website, HTTP is used to exchange
                     information  between  your  computer  and  the  website’s  server
                     (where the website is stored).

                     You may have noticed that some website addresses start with HTTP, while others begin with
                     HTTPS. The "S" in HTTPS stands for Secure. This means the website is using extra protection
                     to keep your data safe when you visit it. HTTPS is used on websites where you enter private
                     information, like passwords or credit card details, ensuring that your data is kept safe while it's
                     sent over the Internet.

                           INTERNET EXPLORER

                     Internet Explorer is a web browser developed by Microsoft. A web browser is a
                     program that lets you access and view websites on the Internet. Internet Explorer
                     was first released in 1995 and became one of the most popular web browsers for
                     many years. It allowed people to visit websites, watch videos and use online tools.

                     Features like tabbed browsing and pop-up blocking made it easier for users to browse safely.

                           WORLD WIDE WEB

                     The  World Wide Web (WWW) is a  large  information  system where  you  can  surf  and  get
                     information. It consists  of several public and private websites which may be interlinked and
                     accessible over the Internet worldwide. WWW is also known as Web.

                     Many people believe that the World Wide Web and the Internet are the same thing, but this is not
                     correct. In fact, these are two different things. The Internet is the global network that connects
                     computers, while the Web is the collection of websites and webpages accessed through that
                     network.

                     Information on the Web is stored in the form of Web pages. A Web page is a hypertext document.
                     A collection of related web pages is called website. Websites are hosted on Web servers. A
                     Web server is an Internet host computer that often store thousands of individual Web pages.
                     Copying a Web page onto a server is called publishing the Web page. This process is also called
                     as posting or uploading.
