Final answer:
The IETF, W3C, and ISO/IEC have a critical role in standardizing network protocols, which are necessary for the operation of the Internet and the World Wide Web.
Step-by-step explanation:
The Internet Engineering Task Force (IETF) works closely with the World Wide Web Consortium (W3C) and the International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC), focusing on network protocols. This collaboration is vital for the standardized communication backbones that allow the global internet and the World Wide Web to function. The IETF primarily develops and promotes voluntary Internet standards, including the TCP/IP protocols, which are fundamental to the operation of the Internet. Meanwhile, the W3C is responsible for developing web standards such as HTML, which Tim Berners-Lee first devised on a NeXT computer, shaping the way web pages are created and displayed. The ISO/IEC plays a role in standardizing various aspects of information technology which may include aspects related to networking protocols as well.
