A computer on internet are identified by-

The correct answer is IP address.

Key Points

• An IP address (Internet Protocol address) is a unique string of numbers separated by periods (IPv4) or colons (IPv6) that identifies each computer using the Internet Protocol to communicate over a network.
• Every device connected to the internet has a unique IP address, which allows it to be identified and located.
• IP addresses are used by network devices to send and receive data packets across the internet.
• There are two types of IP addresses: IPv4 (e.g., 192.168.1.1) and IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
• IP addresses can be static (permanently assigned) or dynamic (temporarily assigned by a DHCP server).

Additional Information

• IP addresses are managed and allocated by the Internet Assigned Numbers Authority (IANA) and regional internet registries (RIRs).
• Network administrators and Internet Service Providers (ISPs) are responsible for assigning IP addresses to devices within their networks.
• IP addresses play a crucial role in routing data packets to their correct destinations on the internet.
• IP addresses can reveal general information about the location of a device, such as the country or city in which it is located.
• Network security and privacy measures often involve managing and protecting IP addresses to prevent unauthorized access and cyber threats.
