Port numbers in the range from 1024 to 49151 are referred to as:

Option 1: Well-known ports.
Option 2: Registered ports.
Option 3: Dynamic ports.
Option 4: Private ports.

Answer 1

Registered ports in computer networking

Step-by-step explanation:

The correct answer is Option 2: Registered ports.

Port numbers in the range from 1024 to 49151 are referred to as registered ports. These ports are used by applications or services that have been registered with the Internet Assigned Numbers Authority (IANA). These ports are not well-known like the ones in the range from 0 to 1023, but they are not dynamic or private either.

For example, port number 80 is a well-known port used by the HTTP protocol, while port number 443 is used for secure HTTP communication (HTTPS). On the other hand, registered ports include port numbers like 22 for SSH, 25 for SMTP, and 143 for IMAP.
