Solaris Interview Question:

What is difference between Process and Daemon in Solaris?

Submitted by: Administrator

A 'daemon' is a software process that runs in the background (continuously) and provides the service to client upon request. For example named is a daemon. When requested it will provide DNS service. Other examples are:

xinetd (it is a super-daemon, it is responsible for invoking other Internet servers when they are needed)
inetd (same as xinetd, but with limited configuration options)
sendmail/postfix (to send/route email)
Apache/httpd (web server)
'server process' run runs one time, when called by a daemon. Once done it will stop. For example telnetd (in.telnetd) or ftpd called from xinetd/inetd daemon . By calling server process from daemon you can save the load and memory. Use a server process for small services such as ftpd, telnetd
