Introduction to Operating System ऑपरेटिंग सिस्टम का परिचय

An Operating System (OS) is system software that acts as an interface between the user and the computer hardware. It manages all hardware resources and provides a platform for application programs to run smoothly. Without an operating system, a computer cannot function effectively.

Operating System (OS) एक सिस्टम सॉफ्टवेयर है जो यूज़र और कंप्यूटर हार्डवेयर के बीच इंटरफेस के रूप में कार्य करता है। यह सभी हार्डवेयर संसाधनों का प्रबंधन करता है और एप्लिकेशन प्रोग्राम्स को चलाने के लिए प्लेटफॉर्म प्रदान करता है। ऑपरेटिंग सिस्टम के बिना कंप्यूटर ठीक से काम नहीं कर सकता।

An operating system controls the execution of programs, manages memory, handles input/output devices, and ensures that different programs and users do not interfere with each other. It acts like a manager that allocates resources whenever required.

ऑपरेटिंग सिस्टम प्रोग्राम्स के निष्पादन को नियंत्रित करता है, मेमोरी का प्रबंधन करता है, इनपुट/आउटपुट डिवाइस को संभालता है और यह सुनिश्चित करता है कि विभिन्न प्रोग्राम या यूज़र एक-दूसरे के काम में बाधा न डालें। यह एक मैनेजर की तरह कार्य करता है जो आवश्यकता अनुसार संसाधन आवंटित करता है।

Definition of Operating System:- 

An operating system can be defined as a set of programs that manage computer hardware and software resources and provide common services to computer programs.

ऑपरेटिंग सिस्टम को प्रोग्राम्स के ऐसे समूह के रूप में परिभाषित किया जा सकता है जो कंप्यूटर के हार्डवेयर और सॉफ्टवेयर संसाधनों का प्रबंधन करता है तथा अन्य प्रोग्राम्स को सामान्य सेवाएँ प्रदान करता है

Need of Operating System:- 

Without an operating system, users would have to interact directly with hardware, which is very complex and time-consuming. The operating system simplifies this interaction and makes the computer system easy to use.

ऑपरेटिंग सिस्टम के बिना यूज़र को सीधे हार्डवेयर से संपर्क करना पड़ेगा, जो बहुत जटिल और समय लेने वाला होता है। ऑपरेटिंग सिस्टम इस प्रक्रिया को सरल बनाता है और कंप्यूटर को उपयोग में आसान बनाता है।

Example:-

When you open a file, the operating system decides:

  • Where the file is stored

  • How much memory is required

  • Which device will display it

जब आप कोई फाइल खोलते हैं, तो ऑपरेटिंग सिस्टम यह तय करता है:

  • फाइल कहाँ संग्रहित है

  • कितनी मेमोरी की आवश्यकता है

  • कौन सा डिवाइस उसे प्रदर्शित करेगा

Real-life Comparison:-

The operating system is like a school principal who manages teachers, students, classrooms, and schedules so that everything runs smoothly.

ऑपरेटिंग सिस्टम एक स्कूल के प्रिंसिपल की तरह है जो शिक्षक, विद्यार्थी, कक्षाएँ और समय-सारणी का प्रबंधन करता है ताकि सभी कार्य सुचारु रूप से चलें।
