organize your files - 2booting the computer =Restarting a computer or its operating system software. It is of two types (1) Cold booting: when the computer is started after having been switched off. (2) Warm booting: when the operating system alone is restarted (without being switched off) after a system crash or 'freeze.' Both types of booting clear out (for the time being) the bugs, bombs, memory conflicts, and other idiosyncrasies of the operating system.
- 3a user interface =Graphical user interface is sometimes shortened to GUI. The user chooses an option usually by pointing a mouse at an icon representing that option
- 4a file management =A file object provides a representation of a resource (either a physical device or a resource located on a physical device) that can be managed by the I/O system. Like other objects, they enable sharing of the resource, they have names, they are protected by object-based security, and they support synchronization.
