Pattern: IP Address & DNS (Introductory Level)

Pattern

एक IP Address network पर किसी device को uniquely identify करता है, जबकि DNS (Domain Name System) easy-to-remember domain names को IP addresses में convert करता है।

Step-by-Step Example

Question

जब आप web browser में www.bankexam.com type करते हैं, तो कौन-सा system इस domain name को IP address में translate करता है?

Options:
A. HTTP
B. FTP
C. DNS

    DNS human-readable domain names को machine-readable IP addresses में convert करता है।

  3. Step 3: Correct option से match करें

    Domain name से IP address में conversion का काम DNS करता है।

  4. Final Answer:

    DNS → Option C

  5. Quick Check:

    Domain name → IP address conversion = DNS ✅

Quick Variations

• Identify करें कि दिया गया example IP Address है या domain name।

• DNS के purpose से जुड़े questions।

• Private vs public IP की basic understanding (intro level)।

Trick to Always Use

  • Step 1: 192.168.1.1 जैसे numbers → IP Address
  • Step 2: google.com जैसे names → Domain Name
  • Step 3: Name से number में conversion → DNS

Summary

Summary

  • IP address internet पर किसी device को uniquely identify करता है।
  • Domain names easy-to-remember website names होते हैं।
