Computer science was an emerging discipline in the late 1950s that began to consider time-sharing between computer users, and later, the possibility of achieving this over wide area networks. J. C. R. Licklider developed the idea of a universal network at the Information Processing Techniques Office (IPTO) of the United States Department of Defense (DoD) Advanced Research Projects Agency (ARPA). Independently, Paul Baran at the RAND Corporation proposed a distributed network based on data in message blocks in the early 1960s, and Donald Davies conceived of packet switching in 1965 at the National Physical Laboratory (NPL), proposing a national commercial data network in the United Kingdom.
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 interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.
The Internet has enabled new forms of social interaction, activities, and social associations. This phenomenon has given rise to the scholarly study of the sociology of the Internet. The early Internet left an impact on some writers who used symbolism to write about it, such as describing the Internet as a "means to connect individuals in a vast invisible net over all the earth."
W3Schools is a freemium educational website for learning coding online. Initially released in 1998, it derives its name from the World Wide Web but is not affiliated with the W3 Consortium. W3Schools offers courses covering all aspects of web development. W3Schools also publishes free HTML templates. It is run by Refsnes Data in Norway. It has an online text editor called TryIt Editor, and readers can edit examples and run the code in a test environment.
W3Schools also offers education in Python, another leading language currently in the Internet and programming as a whole, although their major expertise is in HTML and CSS, hence "W3" referencing the "World Wide Web Corporation (W3C)", the term "W3" is often used to shorten "www." in front of many websites. On top of Python, HTML and CSS, W3S also offers JavaScript, SQL, PHP, C++, C#, C, BootStrap and many others that can boost one's knowledge of programming and how to properly program and code.
On the site, source code examples with explanations are shown free of charge in English, most of which can also be edited and executed interactively in a live editor. Other important code elements are hidden so that the user can focus on the code shown (developer sandbox). The tutorials are divided into individual chapters on the development languages. In addition to the basics, application-related implementation options and examples, as well as a focus on individual elements of the programming language (so-called "references") are documented. In addition, there is a YouTube channel, which takes up and explains certain topics in web development, and an Internet forum. The languages HTML, CSS, JavaScript, JSON, PHP, AngularJS, SQL, Bootstrap, Node.js, jQuery, XQuery, Ajax, and XML are supported.
