OS

GUI

GUI, or graphical user interface allows to user to easily use the computer.  The GUI is what users see when using the computer and allows the user to easily access applications and personalise their computer.  Every operating system has a different GUI.  Using GUI allows me to change the wallpaper to a different photo and easily open the applications I want.

File management

File management allows the user to save, move, rename and easily access file from the directory.  Using file management allowed me to save files to a file so I could easily find it later.

Application execution

Application execution is when the OS opens and closes applications at the will of the user.  OS give the application and icon so the user can find it quickly and easy.  I use application execution whenever I use an application such as Microsoft word or internet explorer.

Input/Output management

The input and output management works out what inputs and outputs are being used and what is necessary for them to be used.  For example a keyboard, the OS works out what buttons are being pushed and what the computer should do when they are pushed.  When I type on the keyboard for a word document, it will add the letter pushed to the document.  The screen, the OS works out what should be displayed on the screen.
