What is the main function of an operating                  system?


Ans-  An operating system (OS) is the most critical software on a computer, acting as an intelligent intermediary between the hardware and the user. Its main function is to manage all hardware and software resources to ensure the system operates efficiently, fairly, and securely.  

​Core Functions

​Resource Management: The OS acts as a manager for the computer's "organs." It decides which applications get to use the CPU and for how long (Processor Management), and allocates specific blocks of RAM to ensure programs don't crash into each other (Memory Management).  

​Hardware Abstraction: It hides the complex technical details of hardware. Instead of a programmer writing code for every specific brand of printer or hard drive, the OS provides a universal interface (Device Management) using drivers.  

​File and Storage Management: It organizes how data is stored, retrieved, and named on your drives. It keeps track of where information resides and manages user permissions to keep data private.  

​User Interface (UI): It provides the visual environment (GUI) or command line (CLI) that allows humans to interact with the machine without needing to speak binary.  

​Essentially, the OS transforms raw electronic components into a functional, user-friendly environment where multiple programs can run simultaneously without conflict.
