Operating System
ऑपरे टटिंग टसस्टम एक ऐसा सॉफ्टवेयर होता है जो टक अन्य किंप्यटू र प्रोग्रामों का सिंचालन यानी
टनयिंत्रण करता है, बोले तो ये किंप्यटू र प्रोग्राम और किंप्यटू र हार्ड वेयर को मैनेज करता है | अगर
टकसी भी लैपटॉप, किंप्यटू र या मोबाइल में ऑपरे टटिंग टसस्टम नहीं हो तो इसके अन्दर कोई भी
सॉफ्टवेयर इिंस्टाल नहीं होगा और ना ही आप इससे कोई काम कर पायेंगे |
नोट: याद कीटजये जब आप अपने किंप्यटू र या लैपटॉप को फॉमेट करते हैं तो सबसे पहले उसमें
टसस्टम सॉफ्टवेयर ही र्ालता है उसके बाद ही एक्सटनड ल सॉफ्टवेयर इिंस्टाल होता है |

 An operating system is software that controls the operation of other computer
programs. It manages computer programs and computer hardware. If there is no operating
system on any laptop, computer or mobile, then no software will be installed in it, nor will
you be able to do any work with it.
Note: Remember that when you format your computer or laptop, first you put the system
software in it, only then the external software is installed.


कुछ ऑपरे टटिंग टसस्टम के उदाहरण....................
(i) Unix: यह ऑपरे टटिंग टसस्टम वर्ड 1969 में टवकटसत
टकया गया मगर वास्तटवक ररलीज़ कुछ समय बाद
टकया गया था | यह Multi Tasking और Multi Users
Operating System है

 This operating system was developed in the year
1969 but the actual release was made after some
time. It is Multi-Tasking and Multi Users Operating
System

टलए होता है |

 This is also the operating system which was
developed in the year 1991. This is the Multi Operating
System that is used for servers.




(iii) मैं आपको बता दूँू की ये ऑपरे टटिंग टसस्टम पहले
माइक्रोसॉफ्ट किंपनी ने बनाया था लेटकन बाद में
“ओरे कल सोलेररस” किंपनी ने हटथया टलया |

 Let me tell you that this operating system was
first created by the Microsoft Company but later the
"Oracle Solaris" company took over.

ऑपरे टटिंग टसस्टम टसिंगल यज ू र के टलए है जो टक
माइक्रोसॉफ्ट के द्वारा टवकटसत टकया गया था |
