A web server is a process whose primary purpose is to server up web pages. The web pages can be static HTML or rendered by JSPs or servlets. Apache is an example of a web server. With JServ or Tomcat (or another servlet container) added on it can provide content created via JSPs/servlets.
An app server, in most cases, is a superset of a web server. It adds the ability to run EJBs. So an app server, such as WebLogic, can serve static HTML, provides a servlet container for running servlets & JSPs, and had an EJB container. (In fact you can run WebLogic in web server or app server mode.)
I'm not sure what you mean by network server, so I will not hazard a guess.
Hope that helps.
John
