Study Notes

Web Application Basics

  • Web Application Definition: A client-server software application accessible through a web browser.
  • Web Application Function: They are dynamic websites with server-side programming, allowing for user interaction, database connections, and browser-based results.

Internet Terminologies

  • World Wide Web: A collection of networked information, resources, visuals, and sounds accessible through a web browser.
  • Host: A computer that transmits data over the internet.
  • Domain Name: A unique identifier for a website, associated with a specific IP address.
  • DNS (Domain Name System): A database linking domain names to their corresponding IP addresses.

Request and Response Model

  • Request-Response Model: A basic communication method where a computer sends a request for data, and the receiving computer responds.
  • HTTP (Hypertext Transfer Protocol): The foundation of World Wide Web data communication, enabling the exchange of hypertext information.
  • HTTP Methods: Common methods are POST, GET, PUT, and DELETE, corresponding to create, read, update, and delete operations.

Web Servers

  • Web Server: A computer that delivers web pages to users.
  • Web server functions: When a user requests a web page, the server retrieves and sends the requested page to the user's browser.
  • Popular Web Servers: Apache (most widely-installed), Microsoft IIS, Nginx, Novell NetWare, Google Web Server (GWS), and IBM Domino servers.

Web Application Architectures

  • Web Application Structure: Typically consists of presentation, business, and data layers.
  • Tiered Design Patterns: Two-tier (client and server), three-tier (client, application server, database server), and n-tier (multiple tiers for security and scalability).

Dynamic vs. Static Web Pages

  • Dynamic Website: Uses HTML, CSS, and website scripting for user interaction and content sharing.
  • Static Website: Uses only HTML and CSS, offering limited interactivity.

Client-Side vs. Server-Side Scripting

  • Client-Side Scripting: Executed by web browsers, viewable by website visitors. Includes technologies like HTML, CSS, JavaScript, Ajax, jQuery, MooTools, and Dojo Toolkit.
  • Server-side Scripting: Executed on the server, invisible to website visitors. Common languages include PHP, Python, Ruby, Java, and .NET.
