UGC NET Questions (Paper – 1)

An IP address uniquely identifies a host or interface on a network using the Internet Protocol so that data packets can be routed correctly. It functions like a digital address, enabling communication between devices. Without IP addresses, the internet could not deliver information to specific destinations. Therefore, the label described in the stem is an IP address.

Option A:
Option A, email address, identifies a mailbox for electronic mail services and not the network interface itself. It cannot be used by routers to forward packets.

Option B:
Option B is correct because IP address is the standard term for the numerical identifier assigned to devices using the Internet Protocol.

Option C:
Option C, MAC address, refers to a hardware address assigned to network interfaces at the data link layer and is distinct from IP addressing at the network layer.

Option D:
Option D, URL link, specifies the location of web resources and is not used for addressing devices in packet routing.
