What is the logical address of a device connected to a network or the Internet called?

1. Media access control (MAC) address

2. Internet Protocol (IP) address

3. Geophysical address

4. Terminal address

The correct answer is: Internet Protocol (IP) address

The logical address of a device connected to a network or the Internet is referred to as the Internet Protocol (IP) address. This address is essential for identifying devices on a network and facilitating communication between them. It provides a unique identifier for each device, allowing data to be routed correctly across the internet. IP addresses can vary in format, such as IPv4, which consists of four sets of numbers separated by dots, or IPv6, which uses a longer hexadecimal format due to the growing number of devices accessing the internet. In contrast, a Media Access Control (MAC) address is a unique identifier assigned to network interfaces for communications at the data link layer. While it is used for local network communication, it does not serve as a logical address for routing over the Internet. The terms 'Geophysical address' and 'Terminal address' are not standard terminology used in computer networking. They do not represent recognized addressing schemes in network communications, making them incorrect in this context. Thus, the IP address remains the appropriate term for the logical address of a device on a network or the Internet.
