single user operating systems

3 functions inside an operating system are: File Management, Input/Output System and the Kernal.

File Management System – This part of the operating system manages all files that are located on the backing storage. Its job is to delete; rename; and create files, loading and saving files to and from disc, and will ensure data is sent to the correct program.

input/output system – this part of the system takes in all the users commands and handles the data and develops the output.. such as reading information from the mouse and keyboard then reacting accordingly, it will also control the sending of information to printers, ensuring the correct information is sent.

the kernal – the kernal is the central main point of an operating system which is connected to all the other parts in the system. tt decides which function gets to use the processor at a given time as a processor can only perform 1 action at once.
