                     Web Applications
                    A web application (or webapp), unlike standalone application, 
                      runs over the Internet. 
                    Examples of webapps are Google, Amazon, Facebook, etc. 
                    A webapp is typically a 3-tier client-server-database application 
                      run over the Internet and it comprises five components:
                       HTTP Server: e.g., Apache HTTP Server, Microsoft Internet 
                         Information Server (IIS), Google Web Server (GWS), etc. 
                       HTTP Client (or Web Browser): e.g., Internet Explorer (MSIE), 
                         FireFox, Chrome, Safari, and etc.
                       Database: e.g., Open-source MySQL, Apache Derby, mSQL, 
                         Oracle, IBM DB2, SAP SyBase, MS SQL Server, etc.
                       Client-Side Programs: could be written in HTML Form, 
                         JavaScript, VBScript, Flash, and others. 
                       Server-Side Programs: could be written in Java Servlet/JSP, 
                         ASP, PHP, Perl, Python, etc.

                    Web Programming
                   For basic Web Programming we use:
                      HTML
                      CSS
                      JavaScript
                   For more Dynamic Web Programming we use, e.g.,
                      ASP.NET
                      SQL
                      AJAX
                      PHP
                      etc.

                      The Client-server Computing Model
                     When you are surfing the Web, you are using a Web browser. 
                     When you go to a website for documents, the site delivers them 
                       using software called the Web server. 
                     The browser is considered to be a client in the relationship 
                       with the server as it is requesting information services from the 
                       server.
                     Users run client programs (i.e. Web browsers) which provide 
                       the following functionality:
                        Allow the user to send a request for information to the server.
                        Format the request so that the server can understand it.
                        Format the response from the server in a way that the user can 
                          read it.
                     Server programs carry out the following:
                        Receive a request from a client and process the request.
                        Respond by sending the requested information back to the 
                          client.          Adv Web Development - Prof. Moheb Ramzy Girgis
