The internet is the largest computer network in the world, connecting millions of computers.
A network is a group of two or more computer systems linked together.
two main types of computer networks:
Local Area Network (LAN): A LAN is two or more connected computers sharing certain resources in a relatively small geographic location.
two main types of computer networks:
Wide Area Network (WAN): A WAN typically consists of two or more LANs. The computers are farther apart and are linked by telephone lines, dedicated telephone lines, or radio waves.
The internet is the largest Wide Area Network (WAN) in existence.
A server is a computer that "serves" many different computers in a network by running specialized software and storing information. For example, web pages are stored on servers.
your computer is acting as a client. A client runs familiar software such as web browsers or email software, and it communicates with the server to get the information it requires.
In peer-to-peer (P2P) networks, each computer acts as both a server and a client. Examples of P2P software include Skype and BitTorrent.
The World Wide Web (WWW)
The internet is the physical network of computers all over the world.
The World Wide Web is a virtual network of web sites connected by hyperlinks (or "links"). Web sites are stored on servers on the internet, so the World Wide Web is a part of the internet.
The backbone of the World Wide Web is made of HTML files, which are specially-formatted documents that can contain links, as well as images and other media. All web browsers can read HTML files.
