Operating system controls the entire system as it has all the entire control. Operating system controls the entire system and nowadays it is GUI that means graphical user interface. User interacts with the system to find the desired output over screen. Operating system has all the load of system and it does all memory allocation. Data needs space in system for storage and operating system provide memory for it. Sometimes data is stored permanently and sometimes temporary.
Operating system provides a virtual memory if data exceeds it’s limits. Data needs more store then the actual one then OSU provides it as data is image based mostly. Text needs less space as compared to image so when image size increases then we can’t hold the data for a long time.
