What is open and close operating system?
A closed operating system is that does not allow you to have
root access to the file system (ex. delete files or change files
related to the graphical interface or how your computer does
things)An example of this type of operating would be iOS which runs
on iPod touches, iPhones, Apple TV, and iPad. An open operating
system is the exact opposite of a closed operating system and is
how all operating systems on a computer work which includes Mac
OSX, Windows 7,XP, Vista, and Linux.
