    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.
