How Apache Works?

    Can someone explain how does Apache works? I see when I start Apache server, 2 httpd processes get created.
    I understand one is the parent, other is the child.
    What do they do?
    I also see that other httpd processes are started and that they are also children. Why and what do they do?

    I am asking the basic questions since I am a complete novice in Apache so please elaborate.
    I am working on a shared Apache module written in Delphi 7 which is acting as a server for client applications running on Windows Mobile 5.0 devices.

    Much appreciated,

    Apache uses the winnt Multi Processing Module (MPM) on Windows.

    http://httpd.apache.org/docs/2.2/mod/mpm_winnt.html
    http://httpd.apache.org/docs/2.4/mod/mpm_winnt.html

    Apache on Linux/Unix is a little diffferent. There are three different MPMs which may be chosen from.

    http://httpd.apache.org/docs/2.2/mpm.html
    http://httpd.apache.org/docs/2.4/mpm.html

    That is about the extent of my knowledge on the subject.
