Answer 1

Answer:

The valid port assignment for the host computer would be D) 1625.

Explanation:

A port number is always associated with an IP address of a host and the protocol type of the communication. The lowest numbered 1024 port numbers identify the historically most commonly used services, and are called the well-known port numbers. Higher-numbered ports are available for general use by applications and are known as ephemeral ports. So in this case, a higher numbered port number should be valid.

D. 80

Explanation:

By default, the port number for a web server is 80.
