What sets out TAR packages from RPM or DEB?

An RPM or DEB package takes care of all the installation with little interaction with the user.

Question 4

DAEMON? Who that?

Answer 4

a DAEMON is a computer program that runs as a background process, rather than being under the direct control of an interactive user.

Traditionally daemon names end with the letter d: for example, syslogd is the daemon that implements the system logging facility and sshd is a daemon that services incoming SSH connections.

Question 5

What is the difference between a tomcat and apache server?

Answer 5

Apache Tomcat is used to deploy your Java Servlets and JSPs. So in your Java project you can build your WAR (short for Web ARchive) file, and just drop it in the deploy directory in Tomcat.

So basically Apache is an HTTP Server, serving HTTP. Tomcat is a Servlet and JSP Server serving Java technologies.
