File>>Create Burn Folder and drag items in then press burn. OR Insert blank media and choose new Burn Folder
This ignores any ownership rules and will grant any logged-on user unlimited access to the contents of the volume.
It starts with a full copy of the system and then it records any changes made to the system and only copies those changes. It creates a simulation of the entire system using hard links for files that didn't change.
Zip files are created with the Finder and are compatible with many OSes. Good for small files & small number of items. Disk Images are created in disk utility.

21. How does the system determine what app to use to open a file?
Disk drive is the hardware itself - partitions are logical divisions of a drive's storage - and volumes are stored inside partitions and define how data is stored to the storage
Option key - Startup Disk preference pane in OS X - or the BootCamp utility in Windows.
The client uses the subnet mask to decide if the client is on the LAN. If it's not on the LAN - then it sends the data to the IP address of the local router. Traffic continues through routers until it reaches the destination.
