Diagnostic ping transport simply asks if servers are alive
When IT tells you they are pinging the network, they are just running a digital pulse check. The ICMP protocol sends a tiny meaningless packet solely to see…

The email setting that quietly deletes server copies
If you setup an old POP3 email account, your phone will greedily hoard all your messages. By default, the protocol downloads your inbox and immediately…
