इंन्टरनेट मध्ये जोडलेल्या संगणकास अॅडरेस असतो, त्यास म्हणतात.

The correct answer is Option A (Internet protocol).

Key Points:
• Every device or computer connected to the Internet or an IP-based computer network is assigned a unique identifying numerical label known as an IP Address (Internet Protocol Address / इंटरनेट प्रोटोकॉल ॲड्रेस).
• An IP address serves two fundamental functions: host/network interface identification and location addressing.
• Major standards:
• IPv4: 32-bit address represented in dotted-decimal format (e.g., `192.168.1.1`).
• IPv6: 128-bit address represented in hexadecimal format to overcome address exhaustion.
• A URL is the address of a specific web document/resource, whereas the hardware/host computer itself is identified on the network by its Internet Protocol (IP) address.
• The official MPSC final answer key confirms Option 1.
• Key Takeaway: The numerical identity assigned to every computer on the Internet is its Internet Protocol (IP) address.
