An IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.

Port 23, on the other hand, is used for TELNET, a protocol that provides a way to remotely access and control a computer. TELNET is not secure and transmits data in plain text, making it less secure compared to SSH. Therefore, the correct answer is that port 22 is used for SSH remote login, while port 23 is used for TELNET.Rate this question:
