An IOS 8 question, can someone explain this?

Posted at: 2014-12-18 
Please help me understand, how does downloading IOS 8 on a computer via iTunes save you space apposed to downloading it directly on your phone with wifi?

If you don't have the required free space on the device and install from a computer with iTunes it uses space on the computer.
