The Internet A single network consists of two or more computers that are connected to share information. The Internet can be defined as a “network of networks” – it connects thousands of networks so information can be exchanged worldwide.

The Internet At one time, connection to the Internet was made through a modem, a device that allows computers to exchange and transmit information through telephone lines. Higher speed broadband connections are available through cable lines or through DSL telephone lines.

The Internet Computers can be linked or networked through wired or wireless (Wi-Fi) connections. Computers that participate in the Internet have a unique numerical Internet protocol (IP) address and usually a name.

The World Wide Web Web browsers allow the user to explore information stored on the Web and to retrieve Web pages the viewer wishes to read. Hypertext is highlighted text or graphics on a Web page that, when clicked, links to other Web sites.

The World Wide Web Hypertext has given rise to the expressions browsing and surfing the Net. Several directories and indexes on the Internet, known as “search engines”, help users find information on a particular topic from the millions of websites located on the Internet.
