Network protocols
“What is a network protocol and why are protocols essential for successful networking between computers?” Any one who’s read a spy novel will have come across the word “protocol” in the context of international diplomacy. Recently HM the Queen visited the school at which I teach. We (the staff) had to attend “protocol sessions” beforehand. “You don’t address senior royalty prior to him/her addressing you” Wait for the Royal to extend his/her hand to you, don’t extend yours first” “On first addressing HM, address her as ‘Your Majesty’, subsequently address her as Ma’am (rhyming with ‘jam’ not sounding like ‘marggghhm’)”.
