Step one: The process of sending an email starts on your device. Once you send your email, it starts a journey to the receving device.
Step two: Next the message is sent to the TCP where it is broken down into packets.
Step three: Then the packets are given an IP address to send them to the correct device
Step four: After getting an IP address the packets are sent to a router. The router sends the packets on the quickest route. Packets don't have to follow the same path, and can take different routes.
Step five: If the deivce is local to the router it is sent to IP. If it is not local it is sent to a local router.
Step six: The Ip sends the packets to the device and checks the IP address
Step seven: Then the packets are sent to the TCP of the receving device which reassimble the packets into the message.It does not matter what order the packets arrive in.
Step eight: Finally the message arrives to the recipent's device within seconds of it being sent.
