The Internet
The Internet is an association of thousands of networks and
millions of computers around the world connected by
communications lines. They all work together to share
information.
The World Wide Web
The World Wide Web (or ‘Web’) is a subset of the Internet —
a collection of interlinked documents (located on computers
connected to the Internet) that work together using a specific
Internet protocol called Hypertext Transfer Protocol (HTTP).
The World Wide Web offers information as text, images,
audio, or video to be referenced from anywhere in the world.
Special programs called Web browsers are specifically
designed to work with HTTP. They make it easier to connect
to a particular network address and send and receive
information.
