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 ARPANet.

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.

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 TCP/IP (for Transmission Control Protocol/Internet Protocol).

Two recent adaptations of Internet technology, the intranet and the extranet, also make use of the TCP/IP protocol.

For most Internet users, electronic mail (email) practically replaced the postal service for short written transactions.

The most widely used part of the Internet is the World Wide Web (often abbreviated "WWW" or called "the Web").

Its outstanding feature is hypertext, 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 browser, the most popular of which are Chrome, Firefox and Internet Explorer.

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, virtual reality, sound, and music files, than earlier versions.

The Internet has continued to grow and evolve over the years of its existence. IPv6, for example, was designed to anticipate enormous future expansion in the number of available IP addresses.

In a related development, the Internet of Things (IoT) is the burgeoning environment in which almost any entity or object can be provided with a unique identifier and the ability to transfer data automatically over the Internet.

When you send a letter, you don’t need to know about the vans, trains and planes that carry it to its destination, or how many post offices it passes through on the way.

Nor do you need to know how your packets of internet data are transmitted through a variety of cables, routers and host computers on the way to their destination.

The internet is a globally connected network system that uses TCP/IP to transmit data via various types of media. The internet is a network of global exchanges – including private, public, business, academic and government networks – connected by guided, wireless and fiber-optic technologies.

However, different packets can take different routes, which makes the internet relatively resilient.

The failure of a particular node or host generally makes little or no difference to the rest of the system.
