Sharing my limited education.
Think of a submarine sending out a sonar 'ping' and then that sound wave hits something hard and shiny that bounces back the sound to the sub so the sub can identify that something is there based on that reply.
That is literally what I always thought the origins were for the networking 'Ping' command. Made sense to me, you send out a targetted ping and if it's reachable, you get a reply.
Apparently, according to this brain-numbing course I'm doing, 'PInG' is actually an acronym.
"Packet Internet Groper".
Awesome name from 20th century geeks.
Turns out I've been 'groping' for years without realising it. Let's hope HR never find out or a quarter of I.T. everywhere will be having difficult conversations.
