Study Notes

Client-Server Concept

  • Client-server systems work together to deliver network services
  • The server initiates communication, sending information back to the client

Client-Server Objectives

  • Students will learn about client-side scripts
  • Students will understand client-side scripting languages
  • Students will learn about server-side scripts

Web Server and Web Browser Interactions

  • Users type a URL into a web browser
  • The browser sends the URL request to the web server
  • Web server accepts, processes the request
  • Sends the information back to the browser
  • The browser displays the requested information

Client-Server Relationships

  • The client-server relationship is fundamental to computer languages on the web
  • Key differences are how the languages are invoked, what resources they access, what structures they manipulate, how they interact with the user and system, and their speed/predictability

Client Side Scripts

  • Scripts are interpreted and executed by the browser
  • Examples include Javascript, JScript, and VBScript
  • Script may be embedded in HTML
  • May be in separate files
  • Validate user input and enhance web pages

Server Side Scripts

  • Server-side scripts run on the server
  • Examples include Python, Perl, PHP
  • Used to generate HTML for the browser
  • Server-side scripts operate independently from the client

XAMPP

  • XAMPP is a web server distribution bundle for PHP applications
  • Included software: Apache, MySQL, PHP, and optional Perl
  • Available for Linux, Windows, Mac OSX, and Solaris
  • Document root directory for Windows is: C:\xampp\htdocs
  • Browser URL alias is http://localhost or http://127.0.0.1

Internet Application- Architecture

  • Top layer - uses support layers from networked application support layer to perform organization functions
  • Composed of networked application support, transport protocol, and network transmission/ communication layers
  • Layers work collectively for application tasks
