What is the Internet?

“The Internet” refers to the worldwide network of interconnected computers, all of which use a common protocol known as TCP/IP to communicate with each other. Every publicly accessible web site is hosted by a web server computer, which is a part of the Internet. Every personal computer, cell phone or other device that people use to look at web sites is also a part of the Internet. The Internet also makes possible email, games and other applications unrelated to the World Wide Web.

The vast collection of interconnected networks that all use the TCP/IP protocols and that evolved from the ARPANET of the late 1960s and early 1970s. The Internet connects roughly 60,000 independent networks into a vast, global Internet.
