Socket and Port Basics Quiz

Source port numbers identify the originating application, while destination port numbers identify the application on the remote host.

A socket is a combination of the source IP address and source port number, or the destination IP address and destination port number.

Well-known ports range from 0 to 1,023 and are reserved for common services and applications.

<p>Registered ports range from 1,024 to 49,151 and are assigned to specific applications, like Cisco's RADIUS server using port 1812.</p> Signup and view all the answers
