Final answer:
The range of ports from 1 to 1023 are known as well-known ports, reserved for universal applications and assigned to server services by IANA, such as HTTP, HTTPS, and FTP.
Step-by-step explanation:
The range of ports from 1 to 1023 are reserved for the most universal applications. These ports are known as well-known ports and they are assigned to specific server services by the Internet Assigned Numbers Authority (IANA). Common examples include port 80 for HTTP, port 443 for HTTPS, and port 21 for FTP. Using these standardized ports ensures that client software can predictably connect to services that are using the well-known system. Ports above 1023 are designated as user or dynamic ports.
