What is www?

• What is www ? || Concept of world wide web || How does it work ? Internet, which is otherwise called an Internet, is an assortment of sites or pages put away in web servers and associated with nearby PCs through the web. These sites contain text pages, computerized pictures, sounds, recordings, and so forth. Clients can get to the substance of these destinations from any region of the planet over the web utilizing their gadgets, for example, PCs, PCs, phones, and so on. The WWW, alongside the web, empowers the recovery and show of text and media to your gadget.

• What is www ? || Concept of world wide web || How does it work ? The structure blocks of the Internet are site pages that are arranged in HTML and associated by joins called "hypertext" or hyperlinks and got to by HTTP. These connections are electronic associations that connect related snippets of data so clients can get to the ideal data rapidly. Hypertext offers the benefit to choose a word or expression from text and hence getting to different pages that give extra data connected with that word or expression.

• A website page is given a web-based address called a Uniform Asset Finder (URL). A specific assortment of site pages that have a place with a particular URL is known as a site, e.g., www.facebook.com, www.google.com, and so forth. Thus, the Internet resembles a gigantic electronic book whose pages are put away on different servers across the world.

• Little sites store each of their Pages on a solitary server, however huge sites or associations put their Pages on various servers in various nations so that when clients of a nation search their site they could get the data rapidly from the closest server.

• In this way, the web gives a correspondence stage to clients to recover and trade data over the web. In contrast to a book, where we move starting with one page and then onto the next in a grouping, on the Internet we follow a snare of hypertext connects to visit a page and from that site page to move to other website pages. You really want a program, which is introduced on your PC, to get to the Internet.

The contrast between the Internet and the Web:

• What is www ? || Concept of world wide web || How does it work ? Certain individuals utilize the terms 'web' and 'Internet' conversely. They assume they are exactly the same thing, however, it isn't the case. The web is totally not quite the same as WWW. It is an overall organization of gadgets like PCs, PCs, tablets, and so forth. It empowers clients to send messages to different clients and visit with them on the web. For instance, when you send an email or talk with somebody on the web, you are utilizing the web.

• In any case, when you have opened a site like google.com for data, you are utilizing the Internet; an organization of servers over the web. You demand a site page from your PC utilizing a program, and the server delivers that page to your program. Your PC is known as a client program (internet browser) and asks the other PC (server) for the data it needs.

History of the Internet:

• What is www ? || Concept of world wide web || How does it work ? The Internet was created by an English researcher, Tim Berners-Lee in 1989. He was working at CERN around then. Initially, it was created by him to satisfy the need for robotized data division among researchers across the world, so they could undoubtedly share the information and aftereffects of their investigations and studies with one another.

• CERN, where Tim Berners worked, is a local area of more than 1700 researchers from more than 100 nations. These researchers invest some energy in the CERN site, and the rest of the time they work at their colleges and public labs in their nations of origin, so there was a requirement for dependable specialized devices with the goal can trade data.

• Web and Hypertext were accessible now, yet nobody figured out how to utilize the web to connect or offer one record to another. Tim zeroed in on three primary advancements that could cause PCs to see one another, HTML, URL, and HTTP. In this way, the level head behind the development of WWW was to join late PC innovations, information organizations, and hypertext into an easy-to-understand and powerful worldwide data framework.

How does the Internet Function?

• What is www ? || Concept of world wide web || How does it work ? Presently, we have perceived that WWW is an assortment of sites associated with the web so that individuals can look at and share data. Presently, let us comprehend how it works!

• The Internet functions according to the web's fundamental client-server design as displayed in the accompanying picture. The servers store and move pages or data to clients' PCs in the organization when mentioned by the clients. A web server is a product program that serves the pages mentioned by web clients utilizing a program. The PC of a client who solicitations reports from a server is known as a client. The program, which is introduced on the client's PC, permits clients to see the recovered reports.

• Every one of the sites is put away in web servers. Similarly, as somebody lives on lease in a house, a site consumes space in a server and remains put away in it. The server has the site at whatever point a client demands its Pages, and the site proprietor needs to follow through on the facilitating cost for something similar.

• The second you open the program and type a URL in the location bar or search something on Google, the WWW begins working. There are three principal advances engaged with moving data (pages) from servers to clients (PCs of clients). These advances incorporate Hypertext Markup Language (HTML), Hypertext Move Convention (HTTP), and Internet browsers.

Hypertext Markup Language (HTML):

• What is www ? || Concept of world wide web || How does it work ? HTML is a standard markup language that is utilized for making site pages. It depicts the construction of website pages through HTML components or labels. These labels are utilized to arrange the bits of content, for example, 'heading,' 'passage,' 'table,' 'Picture,' and that's only the tip of the iceberg. You don't see HTML labels when you open a site page as programs don't show the labels and use them just to deliver the substance of a site page. In basic words, HTML is utilized to show text, pictures, and different assets through an Internet browser.

Web Browser:

• What is www ? || Concept of world wide web || How does it work ? An internet browser, which is generally known as a program, is a program that shows text, information, pictures, recordings, and liveliness, from there, the sky is the limit. It gives a product interface that permits you to click hyperlinked assets on the Internet. At the point when you double tap the Program symbol introduced on your PC to send off it, you get associated with the Internet and can look through Google or type a URL into the location bar.

• Initially, programs were utilized exclusively for perusing because of their restricted potential. Today, they are further developed; alongside perusing you can involve them for messaging, moving sight and sound records, utilizing web-based entertainment destinations, and partaking in web-based conversation gatherings and the sky is the limit from there. A portion of the normally utilized programs incorporate Google Chrome, Mozilla Firefox, Web Pilgrim, and Safari, and that's only the tip of the iceberg.

Hypertext Transfer Protocol (HTTP):

• Hyper Text Move Convention (HTTP) is an application layer convention that empowers WWW to work without a hitch and successfully. It depends on a client-server model. The client is an internet browser that speaks with the web server which has the site. This convention characterizes how messages are organized and communicated and what moves the Internet Server and program ought to make in light of various orders. At the point when you enter a URL in the program, an HTTP order is shipped off the Internet server, and it sends the mentioned Website page.

• At the point when we open a site utilizing a program, an association with the web server is opened, and the program speaks with the server through HTTP and sends a solicitation. HTTP is persisted TCP/IP to speak with the server. The server processes the program's solicitation and sends a reaction, and afterward, the association is shut. In this manner, the program recovers the content from the server for the client.
