What are the various parts of an Operating System?

 

In this section we look at that part of the operating system that is responsible for running programs, called the real-time executive or kernel. An operating system for a large-scale computer that is used by many people at once is a very complex system. It contains many millions of lines of instructions (commands that the computer executes) written by programmers. To make operating systems easier to write, they are constructed as a series of modules (programs), each module responsible for one function. Typical modules in a larger multi-user operating system could be:

• Kernel (also known as the executive)
  
• Process manager
  
• Scheduler
  
• File manager
