Functions of an Operating System
An Operating System performs various Functions that ensure the Smooth execution of computer programs and user interactions. Some of the key functions include-
Process Management: The OS manages Processes, allocating system resources to execute Programs efficiently.
Memory Management: It handles RAM allocation, ensuring each program gets the required Memory for execution.
File System Management: The OS organizes and manages Files, Directories, and Storage devices.
Device Management: It communicates with Hardware devices such as Printers, Scanners, and Keyboards.
User Interface: The OS provides a User-friendly Interface to interact with the Computer.
Security Management: It ensures data and system security by controlling access to resources.
Types of Operating Systems
Operating Systems (OS) can be Classified into Various Types based on their Usage and Design. The Main types include-
Single-User, Single-Tasking OS
This type allows only one User to run one Program at a time. Early Operating Systems like MS-DOS is an example of Single-user, Single-tasking OS.
Single-User, Multi-Tasking OS
In this type, a single User can run multiple programs simultaneously. Modern Desktop OS like Windows and macOS are examples of Single-user, Multi-tasking OS.
Multi-User OS
These Operating Systems support multiple Users simultaneously, each running their own Processes. Unix-based systems like Linux are popular Multi-user OSs.
Real-Time OS
Real-Time OS is designed to handle real-time Applications, where Response time is Critical. They are used in Industries like Aerospace and Robotics.
Importance of Operating Systems
Operating Systems play a vital Role in the World of computing, and their Importance cannot be understated. Some Key reasons why Operating Systems are Essential-
Resource Management: OS efficiently manages Computer resources, ensuring Optimal Utilization.
