what exactly happening while Data from source to destination

Hi Team,

I am new to this blog. I have this question in my mind a long days. I asked this question to someone, but the information is not enough for me.

As we know about OSI layer plays a vital role in Networking. Each and every layer is responsible for data to reach destination whether it is in same or different LAN. Initially Binary(physical) data --> frame( data link ) -->packet( Network ) --> segment --> ( Transport ) --> session ( port )--> presentation (data format ) --> Application ( UI )

For example if we sending mail form outlook, data processed from Application layer and continues to reach destination. My question is how many times each layer functions are required when data from source to destination.

According to my understanding, PC's application layer --> PC's presentation layer --> Pc's etc........while reaching Ethernet physical port of PC (i.e) Lan port in Pc, how many layer functions done. Then what process will take to travel in to ethernet cable --> switch --> router --> WAN --> router --> switch --> server

Please help me to know actual process happening when data travelling from client source to server destination.
