What's the internet

The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.

what is web site

A website (also written as web site) is a collection of web pages and related content that is identified by a common domain name and published on at least one web server. Notable examples are wikipedia.org, google.com, and amazon.com.


All publicly accessible websites collectively constitute the World Wide Web. There are also private websites that can only be accessed on a private network, such as a company's internal website for its employees.


Websites are typically dedicated to a particular topic or purpose, such as news, education, commerce, entertainment, or social networking. Hyperlinking between web pages guides the navigation of the site, which often starts with a home page.


Users can access websites on a range of devices, including desktops, laptops, tablets, and smartphones. The software application used on these devices is called a web browser.


web creator

The World Wide Web (WWW) was created in 1990 by the British CERN physicist Tim Berners-Lee.On 30 April 1993, CERN announced that the World Wide Web would be free to use for anyone.


Before the introduction of the Hypertext Transfer Protocol (HTTP), other protocols such as File Transfer Protocol and the gopher protocol were used to retrieve individual files from a server. 


These protocols offer a simple directory structure which the user navigates and where they choose files to download. Documents were most often presented as plain text files without formatting or were encoded in word processor formats.


Web Definition 

The Web is the common name for the World Wide Web, a subset of the Internet consisting of the pages that can be accessed by a Web browser. Many people assume that the Web is the same as the Internet, and use these terms interchangeably. However, the term Internet actually refers to the global network of servers that makes the information sharing that happens over the Web possible. So, although the Web does make up a large portion of the Internet, but they are not one and same.


Most Commonly Used Languages

There is a variety of coding languages developers choose from, and most use the language they are most comfortable with. Their preference is formed over time based on their experience using different languages. 

Here the most common Web language:

1.Html

2.Css

3.Java

4.JAVASCRIPT

5.PYTHON

6.SQL

7.PHP

8.NET

What is the dark web, deep web, and surface web?

The Internet is sizable with millions of web pages, databases, and servers all run 24 hours a day. But the so-called "visible" Internet (aka surface web or open web) — sites that can be found using search engines like Google and Yahoo — is just the tip of the iceberg.


There are several terms surrounding the non-visible Web, but it's worth knowing how they differ if you're planning to browse off the beaten path.


The surface web or open web

The open web, or surface web, is the “visible” surface layer. If we continue to visualize the entire web like an iceberg, the open web would be the top portion that’s above the water. From a statistical standpoint, this collective of websites and data makes up under 5% of the total internet.


All commonly public-facing websites accessed via traditional browsers like Google Chrome, Internet Explorer, and Firefox are contained here. Websites are usually labeled with registry operators like “.com” and “.org” and can be easily located with popular search engines.


Locating surface web websites is possible because search engines can index the web via visible links (a process called “crawling” due to the search engine traveling the web like a spider).


The deep web

The deep web rests below the surface and accounts for approximately 90% of all websites. This would be the part of an iceberg beneath the water, much larger than the surface web. In fact, this hidden web is so large that it's impossible to discover exactly how many pages or websites are active at any one time.


Carrying on with the analogy, big search engines could be considered like fishing boats that can only "catch" websites close to the surface. Everything else, from academic journals to private databases and more illicit content, is out of reach. This deep web also includes the portion that we know as the dark web.


The dark web

The dark web refers to sites that are not indexed and only accessible via specialized web browsers. Significantly smaller than the tiny surface web, the dark web is considered a part of the deep web. Using our ocean and iceberg visual, the dark web would be the bottom tip of the submerged iceberg.


The dark web, however, is a very concealed portion of the deep web that few will ever interact with or even see. In other words, the deep web covers everything under the surface that's still accessible with the right software, including the dark web... More read

Understanding Web 3.0: The Future of the Internet

Image
The evolution of the internet has been marked by significant milestones, from the early days of Web 1.0 to the current Web 2.0. However, a new phase, known as Web 3.0, is on the horizon, and it promises to revolutionize how we interact with the digital world. Web 3.0, often referred to as the " decentralized web," represents a shift towards a more open, user-centric internet that is powered by blockchain technology, decentralized applications (dApps), and enhanced privacy features. What is Web 3.0? Web 3.0 is the next stage in the evolution of the internet. While Web 1.0 was a static web where users could only consume content and Web 2.0 enabled interaction and social networking, Web 3.0 introduces a decentralized architecture where users have more control over their data, identity, and digital assets. At the core of Web 3.0 is blockchain technology, which allows for secure, transparent, and decentralized transactions. Unlike Web 2.0, where major corporations like Google, F...
