why internet is called network of networks
Before explaining the above question letБs get a fair idea about Internet. Internet, also known as World Wide Web, is a global system of interconnected computer networks that use the standard internet protocol suite (TCP/IP) which connects billions of users worldwide. Initially networks like BBS system, Milnet, DAPRANET were not interconnected to each other and that led to the base concept of connecting these wide numbers of networks together via a new strong global connection called the Internet. With its wide range of applications, Internet is not just one network rather it is called the network of networks. Millions of private firms, public sectors, government offices, academic institutions and business networks of local as well as global status are connected by Internet. All these networks are linked together by a broad array of wireless, electronic and optical wiring technology. Internet is the source of unlimited amount of information and services, such as the hypertext documents of World Wide Web and the whole structure that support the e-mail service. The amazing feature of hypertext is a method of cross referencing as you must have noticed in certain websites that words or sentences appear in different color and are underlined.
You just have to click on those words or sentences and you will be directed to a new network. This shows internet is interconnected via a number of networks. Internet is like a huge working network, as there are dozens of computers in the city and all these computers are linked together as a local area network (LAN). And there are hundreds of such LANs in cities, in a wider area, called БWANБ or wide area network. You will be amazed that thousands of WANs are spread across the entire earth and connected via Bridges transferring information around the world. So, internet is like network of networks spread across the entire world like a web.
The Internet, sometimes called simply the Net, is a worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer (and sometimes talk directly to users at other computers). It was conceived by the Advanced Research Projects Agency (ARPA) of the U. S. government in 1969 and was first known as the. The original aim was to create a network that would allow users of a research computer at one university to talk to research computers at other universities.
A side benefit of ARPANet's design was that, because messages could be routed or rerouted in more than one direction, the network could continue to function even if parts of it were destroyed in the event of a military attack or other disaster. Today, the Internet is a public, cooperative and self-sustaining facility accessible to hundreds of millions of people worldwide. Physically, the Internet uses a portion of the total resources of the currently existing public telecommunication networks. Technically, what distinguishes the Internet is its use of a set of protocols called (for Transmission Control Protocol/Internet Protocol). Two recent adaptations of Internet technology, the and the, also make use of the TCP/IP protocol. For most Internet users, electronic mail ( ) practically replaced the postal service for short written transactions. People communicate over the Internet in a number of other ways including Internet Relay Chat ( ), video chat or. The most widely used part of the Internet is the (often abbreviated WWW or called the Web ). Its outstanding feature is, a method of instant cross-referencing. In most Web sites, certain words or phrases appear in text of a different color than the rest; often this text is also underlined.
When you select one of these words or phrases, you will be transferred to the site or page that is relevant to this word or phrase. Sometimes there are buttons, images, or portions of images that are clickable. If you move the pointer over a spot on a Web site and the pointer changes into a hand, this indicates that you can click and be transferred to another site. Using the Web, you have access to billions of pages of information. Web browsing is done with a Web, the most popular of which are, and. The appearance of a particular Web site may vary slightly depending on the browser you use. Also, later versions of a particular browser are able to render more bells and whistles such as animation, sound, and music files, than earlier versions. The Internet has continued to grow and evolve over the years of its existence. , for example, was designed to anticipate enormous future expansion in the number of available. In a related development, the Internet of Things ( ) is the burgeoning environment in which almost any entity or object can be provided with a and the ability to transfer data automatically over the Internet.
