difference btw apache , tomcat and jakarta

madmax

can anybody tell me what is the difference btw apache , tomcat and jakarta.
i know tomcat is a application server based on java technology - so can i called it java server .
apache is a web server like windows IIS.
apache is a association and they a have a project name jakarta -which works on java technology and one of them project names is tomcat.
i am not sure jakarta by itself a server yes|no?
