How CLoning Process works in the background???

Dear VMware Experts,

I want to know " How CLoning Process works in the background???" , as per my understanding is it work like this

1) Snapshot a Cloned VM

2) Registering a VM to a destination host

3)Copy the .vmdk files to a destination host

4)commit the snapshot disk to the destination host (changed blocks r commited)

Can sum1 brief the cloning process.....
