The internet
Internet is a network connecting many computer networks and based on a common addressing system and communications protocol. The earliest idea of a computer network intended to allow general communication between users of various computers was the ARPANET, the world’s first packet switching network. It was in December 1969 that ARPA (Advanced Research Projects Agency) went online connecting four major U.S. universities. Designed for research, education, and government organizations, it provides a communications network linking the country in the event that a military attack destroys conventional communications systems.
In 1973, the Transmission Control Protocol/Internet Protocol (TCP/IP) was designed and in 1983 it became the standard for communicating between computers over the Internet. In 1976, US Presidential candidate Jimmy Carter and running mate Walter Mondale used email to plan campaign events. In the same year, Queen Elizabeth sent her first email, becoming the first state leader to do so. In 1982, the term “Internet” was used for the first time. The internet is a collection of a large number of client-server based systems. So all files and other resources on it are stored on secondary storage devices of the respective servers. Servers of websites are termed as web servers. When we type in a URL of a website in the address bar of browser, it makes a connection to that web server which in turn fetches the data from the secondary storage device (such as the hard disk) that they must be using and returns it to the respective browser. The same holds true for any other resource (image, MP3 file, zipped file, etc.) that you access on the internet. Web-site and web-page
A website is a collection of linked documents and content associated with a single organization, person, group, or topic and usually sharing a server and a domain name.A web page (usually two words) is a single page of content on a website. A web page or webpage is a document commonly written in HyperText Markup Language (HTML) that is accessible through the Internet or other network using an Internet browsersuch as Firefox, Google Chrome, Microsoft Internet Explorer or Edge, or Apple's Safari. A web page is accessed by entering a URL address and may contain text, graphics, and hyperlinks to other web pages and files.The first web page was created at CERN by Tim Berners-Lee on August 6, 1991.
Difference between website and web page. Web site is collection of webpages which are grouped together and usually connected together in various ways. Often called a "web site" or simply a "site."A website refers to a central location that contains more than one web page. For example, Computer Hope is considered a website, which contains thousands of different pages.
In the above example of a URL, the web page is "url.htm" and is always the last part of the URL. For URL's that do not have an ending of .htm, .html, .php, .cgi, .pl, or other file extension, the server is loading the default index.htm web page in that directory.
