DNS Domain Name System definition in Hindi, Understand DNS Server
Domain Name System क्या होता है? DNS definition : Domain Name System को short मे DNS भी कहते है |DNS का काम Domain Name को IP Address मे convert करना होता है | जब हम किसी भी domain name को web browser मे टाइप करते है तो ये DNS उसको IP Address मे कन्वर्ट करता है | इसी प्रकार किसी भी Network मे किसी भी Computer एवं host name को भी ये IP Address मे कन्वर्ट करता है| यह इसलिए होता है क्योकि हम IP Address की तुलना मे Alphanumeric Name easily याद रख सकते है |एक उदहारण की लिए – जब हम www.example.com को browser मे टाइप करते है तो DNS इसको 198.15.45.18 मे या इसी प्रकार की किसी valid IP Address मे चेंज केर देता है| अब आप खुद देखिए हमको WWW.example.com याद करना कितना आसान है जबकि IP address याद करना कितना मुश्किल|
DNS Domain Name System
अब हम जानते है की Public IP Address के केस मे अनगिनत DNS और IP Address हो सकते है तो केवल एक सर्वर सभी की information को save करके नहीं रख सकता, इसी वजह से जब query एक सर्वर के पास आती है एवं उस सर्वर को IP Address नहीं पता होता या वो उस query को resolve नहीं कर पता तो वो query को उससे connected दूसरे सर्वर के पास भेज देता है| यह Pass on तब तक चलता है जब तक query resolve नहीं हो जाती एवं IP Address नहीं मिल जाता|
DNS implements a distributed database to store this name and address information for all public hosts on the Internet.
