ephemeral port numbers and well known port numbers
Lasting for a very short time, short-lived; transitory: the ephemeral joys of childhood. It can mean "lasting one day". As in Ephemeral Flowers, they last one day. Or in computer terminology an ephemeral port is a transport protocol port for Internet Protocol communications where each client process is assigned a temporary port number for its use. When that process is complete the port is closed.
Ephemeral port numbers and well-known port numbers.
A non-ephemeral port, also known as a well-known or registered port, is a port number that is typically reserved for specific services and applications. These ports range from 0 to 1023 for well-known ports and from 1024 to 49151 for registered ports. Unlike ephemeral ports, which are temporary and assigned dynamically for client-side connections, non-ephemeral ports are usually static and associated with server applications, such as HTTP (port 80) or FTP (port 21). They facilitate consistent communication between clients and servers.
Ephemeral port
We must believe that bad times last ephemeral. Ephemeral means time that does not last for long.
Ephemeral Museum was created in 2008.
That is correct. Ephemeral and evanescent are synonyms.
That is the correct spelling of "ephemeral" (short-lived, or fleeting).
"The joys of childhood only seem ephemeral in retrospect." "Large gains in stock prices are often ephemeral." "The lives of most insects are ephemeral, so the exceptions are more remarkable."
The word "ephemeral" is an adjective. It describes something that lasts for a very short time or has a short lifespan.
The beauty of a blooming flower is ephemeral, lasting only a few days before wilting.
