The Internet Engineering Task Force (IETF) is responsible for overseeing how the Internet s TCP/IP protocols evolve. For information about the IETF, go to www.ietf.org.
The World Wide Web Consortium (W3C) develops standards for the evolution of the most well-known part of the Internet, the World Wide Web (find it World Wide Web (find it at at www.w www.w3.org 3.org). ). The W3C is an industry consortium run by the Laboratory for Computer Science at the Massachusetts Institute of Technology (MIT).
