The Internet is an interconnected network of networks, while the web is a collection of documents connected by universal resource locator (URL) codes and hypertext protocol. The Internet also includes e-mail, fi le transfers, and instant messaging. Although many web-based services have reached out to support these protocols, these protocols were well in place before the web was created. The Internet had its beginning in 1969 with an Advanced Research Projects Agency (ARPA) grant to create communication between remote computers. The fi rst communications network, ARPANET, included computers at University of California at Los Angeles, University of California at Santa Barbara, University of Utah, and Stanford University. The fi nal step that created what is known today as the Internet was the defi nition of the transmission control protocol/Internet protocol (TCP/IP) standards in 1982. The Internetworking Group was responsible for defi ning how a network of networks would communicate. The formal name of Internet came from that group’s name.
