The internet is a loosely organized collection of over 25,000 networks accessed by computers worldwide. It has no central ownership, services, or comprehensive index. Information is coordinated through the standardized TCP/IP protocol. To access the internet, a computer needs a server with special software using this protocol. The internet connects commercial, industrial, scientific, educational, and other sectors and its vast information continues to grow each day. Users can browse the internet, particularly the World Wide Web, by clicking on screen icons to surf linked text, images, and sounds. Many experts predict the internet will become the center of online global communications and even extend to interplanetary communication in the future.
