The Operating system offers different features

The Operating system is designed to hide the complexity of the PC's hardware. In order to achieve this it offers different features.
  • Provides an interface between computer and the user
  • Input and output devices can be controlled
  • The system's recources are managed by the OS and can also be easily managed by the user using the OS.
  • external image Simple_Operating_System_diagram.pngReads and writes from or to a disk, also providing an interface for the user to manage the files
  • Controls user access rights, by restricting different actions or interfaces

This shows that the operating system hides the hardware's complexity by providing an user friendly interface and controlling the system's resources so that the user has a better experience.

Types of Operating System
There are usually two types of Operating Systems dependant on how they process data:
  • Processing in real time (Used more commonly on everyday systems, and when there are few requests to process)
    • Processing requests are run immediatley when demanded by the use
  • Processing in batches (Used within mainframes and servers, when there are many processing requests)
    • "Processing requests are grouped together and run at once" (Citizendium)
