Example: what is internet

The Internet, sometimes called simply "the Net," 
is a worldwide system of computer networks -
a network of networks in which users at any 
one computer can, if they have permission, 
get information from any other computer.
Physically, the Internet uses a portion 
of the total resources of the currently 
existing public telecommunication networks.
Technically, what distinguishes the
Internet is its use of a set of protocols
called TCP/IP (for Transmission Control 
Protocol/Internet Protocol). Two recent 
adaptations of Internet technology, the 
intranet and the extranet, also make use 
of the TCP/IP protocol.
