Features of the contemporary operating system (OS) and their structures

 One of the main features of a current OS is to provide the user with an environment where they can execute programs on a platform that is convenient to navigate on (Silberschatz 2014).  The OS is a control program that supervises the execution of a user program to prevent errors and improper use of the computer.  Furthermore, an OS also manages the operations/control of the input and output devices of the system.

The OS has control of many functions and is structured in a way that maintains a fully function environment for that particular user or many users.  Some of the major functions of the OS are a graphical user interface (GUI), processor management, memory management, device management, job accounting, network management, and file management just to name a few.
