I want to know the difference between the Full Install on USB and Live USB.
Specifically I'm confused about the thing that which runs directly from the USB without installing it on Computer's HDD because I frequently work on different computers so I'm not going to install it on every computer and work from it.
In addition, I also want to boot the OS as fast as possible.
It'll be great if someone can give me full explanation of how OS loads, run etc which will be helpful in increasing my ill knowledge.
And also please suggest me a feasible option by considering all the factors like reads/writes etc so that I can plug and work for a maximum frequency.
The OS I need to work on is Kali Linux.
