Question: In the URL HTTP://xxxx:yyyy/zzzz, the name of the port is _________.

Answer:

In the URL `HTTP://xxxx:yyyy/zzzz`, the name of the port is represented by `yyyy`. The port number is used to identify a specific communication endpoint within a host. In the case of HTTP, the default port number is 80. However, it is common to include the port number explicitly in the URL when it deviates from the default. The port number helps direct the request to the appropriate service running on the server.
