tcp - Port and IP address - what does bind mean? -

-

  1. i read on ports wiki page "ports logical constructs identifies service or process", service or process means here? means protocol http, ftp etc. or software applications configured listen on port?
  2. when said application listening on , so... listen request ip address or port, or listens on combination of port , ip address? application listen specific ip address , 1 or more ports bound or listens combination of ip , port?
    • for example, can have application configured 7001 http requests , 7002 https requests. so, listening on 7001 or what?

  1. applications/services such http web server or ftp server assigned port use/listen on, in config of application. , use standard port. http example uses port 80.

  2. if app/service listening listens port , has no relation specific ip address. because ip address listening on ip address of computer app/service running on.
