 What is an Operating System? 🧠 (Nepali-English Mixed Guide)

Introduction: What is an Operating System? 👨‍🏫

Operating System (OS) भनेको कम्प्युटरको मुख्य software हो जसले hardware र user बीच bridge जस्तो काम गर्छ। Englishमा भन्ने हो भने An Operating System (OS) is system software that manages computer hardware and software resources, and provides services for computer programs। Without OS, computer चलाउन मुश्किल हुन्छ, किनभने सबै काम manually गर्नुपर्थ्यो।

Nepali मा:
अपरेटिङ सिस्टम (OS) भन्ने कम्प्युटरमा चल्ने अत्यावश्यक सफ्टवेयर हो जसले कम्प्युटरको सम्पूर्ण operation (सञ्चालन), resources (CPU, RAM, Storage आदि), र security व्यवस्थापन गर्छ।

Key Points

• 🧠 Operating System कम्प्युटरको basis हो।
• 🛤️ User र hardware बीच interface गर्छ।
• 🖥️ Types: Batch, Real-time, Mobile, Network, etc.
• 🪟 Examples: Windows, Linux, MacOS, Android, iOS.
• 📅 OS इतिहास: 1940s-बाट आजसम्म Develop हुँदै आएको छ।
• 💪 Advantages: Simple, Secure, Multi-tasking, Resource Management.
• ❗ Disadvantages: Hardware requirement, Compatibility Issue, Update problem.

Functions of Operating System (OS का मुख्य कामहरू)

🌟 Main Function	💡 Simple Meaning	🏷️ नेपाली अर्थ
🖥️ Hardware Control	Manages CPU, RAM, Devices	हार्डवेयर (CPU, RAM) को management
📁 File Management	Saving, opening, organizing files	फाइल & फोल्डरको व्यवस्थापन
⚖️ Resource Allocation	Shares memory, CPU among apps	Source बाँडफाँड (Apps चलाउँदा)
🔐 Security	Password, Permissions, Virus Safety	सुरक्षा, अनुमति, प्रमाणिकरण
📝 Task Management	Runs multiple programs at a time (multitasking)	मल्टि-टास्किंग, प्रोसेस मेनेजमेन्ट
🌐 Networking	Connects to Internet, File sharing	नेटवर्किङ, इन्टरनेट/फाइल सेयर

Why is OS Important? (OS किन चाहिन्छ?)

• OS नहुँदा hardware control गर्न command (code) जान्नुपर्ने।
• OS को कारण apps चलाउन, documents safe राख्न, security पाउन सजिलो हुन्छ।
• OS ले सबै फरक hardware को लागी एकीकरण (integration) गर्छ।

Types of Operating System (OS का किसिमहरू)

1. Batch Operating System (ब्याच OS)

• One task at a time, एकैपटक धेरै काम (batch) बनाएर चलाइन्छ।
• Example: Early Payroll system, Printed Job Cards.

2. Multi-Tasking/Time Sharing OS (मल्टि टास्किंग OS)

• धेरै user वा Programs लाई time-sharing गरेर सेवा दिने।
• Example: Windows, Linux, MacOS.

3. Multiprocessing OS (मल्टि प्रोसेसिंग OS)

• धेरै processors प्रयोग गरेर काम छिटो सम्पन्न गर्ने।
• Example: Linux server, Windows Server.

4. Real-Time OS (RTOS)

• समयमै critical काम चलाउने, delay हुँदैन।
• Example: Medical Equipment, Air Traffic Control.

5. Distributed OS

• जति पनि computer मिलेर resources share गर्ने।
• Example: Clustered servers, Cloud OS.

6. Network OS

• Networking र Resource sharing मा focus।
• Example: Windows Server, Novell NetWare.

• Batch OS: काम थुपारेर चलाउने।
• Multi-programming: धेरै काम सँगै।

🗝️ 1970s: UNIX & परिष्कृत तरीका

• UNIX (Bell Labs): Simple र मल्टि-यूजर।
• PCs (Personal Computers) मा CP/M, MS-DOS सुरु।

🎨 1980–90s: GUI & Networking

• Graphical Interface (Windows 3.1, Macintosh)।
• Networking features (file sharing, printers, etc.)
