Ping

23 August 2017 - 11:04 AM

Sharing my limited education.


H:\>ping -n 2 8.8.8.8
 
Pinging 8.8.8.8 with 32 bytes of data:
Reply from 8.8.8.8: bytes=32 time=11ms TTL=50
Reply from 8.8.8.8: bytes=32 time=4ms TTL=50
 
Ping statistics for 8.8.8.8:
    Packets: Sent = 2, Received = 2, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 4ms, Maximum = 11ms, Average = 7ms

 

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.

Upgrade Australia - Sydney 2017

22 August 2017 - 11:23 AM

Was hoping to have my PC built by the next Upgrade Australia. Didn't think Sydney was getting one this year but just found out it is on in a month.  I think I'm too busy with other things to get it done in time now.  But I'm not sure if they are doing the whole bring in your own PC to test it's OC ability this time 'round anyway.

 

So much on that weekend, but I think I'll make it anyway.

Came across this just now. Things one can do with magnets gets a tad more complex with what these people have developed.
