Define and describe non-ephemeral ports

Define and describe ephemeral ports
Temporary port numbers for temporary usage, Ports 1,024-65,535, usually determined in real-time by the client
True or False: TCP and UDP ports have predetermined sets of ports they can use
False - TCP and UDP ports can be any number 0-65,535
True or False: Most servers use non-ephemeral port numbers
