System Software

System Software Computer System का एक महत्वपूर्ण भाग है जो Hardware और User के बीच Interface का कार्य करता है। यह Computer Resources को Manage करता है तथा Application Programs को Execute करने के लिए आवश्यक वातावरण प्रदान करता है। System Software के बिना Computer Hardware उपयोगी नहीं हो सकता।

Introduction

Computer System मुख्यतः Hardware तथा Software से मिलकर बना होता है। Software दो प्रकार के होते हैं – System Software तथा Application Software। System Software Computer के मूल संचालन को नियंत्रित करता है और Hardware Components को Efficient तरीके से Manage करता है।

जब Computer Start होता है तब सबसे पहले System Software ही कार्य करता है। यह Memory Management, Process Management, Device Control तथा File Management जैसे कार्यों को नियंत्रित करता है।

Definition of System Software

System Software उन Programs का समूह है जो Computer Hardware को Manage करते हैं तथा Application Software के संचालन के लिए Platform प्रदान करते हैं।

System Software = Hardware Management + Resource Control + Platform Support
