Draw a diagram of the protocol stack that allows the Web to operate. This stack should include all of the key protocols that are necessary, and depict the hierarchy of the protocols (e.g., high-level protocols that make use of the services of low-level protocols). Protocols that are part of the Internet but not necessary for the Web should be excluded. Use acronyms in the labelling of your diagram, and provide a list of the acronyms with their full names
