The Internet
The Internet is a global network connecting millions of computers through over 100 countries. One key aspect of the Internet is that it is not centraly controled by a server like other types of networks. By design the Internet is decentralized, meaning that each computer called a host acts independantly of other hosts unless instructed otherwise. An operator can chose what Internet services to use and what local services to make available to other hosts on the Internet. Once connected to the Internet a host has a choice of services that it can use from email, chatting, file sharing, web radio, webTV, and many more. The Internet was first implemented back in the 1960's, and was first named the ARPAnet.
