    Study Notes

    Client-Server Concept

    • Client-server systems involve clients initiating communication, and servers responding with information.
    • Clients request services, and servers provide them.
    • The server typically holds resources and information.
    • The client typically initiates requests.

    Client-Side Scripting

    • Client-side scripts run on the user's computer (browser).
    • They are typically interpreted by the browser.
    • Client-side languages enhance web pages.
    • Client-side scripts are not processed on the server.
    • Client-side scripts are embedded in HTML documents.
    • JavaScript, JScript and VBScript are common client-side languages.
    • They are often used for validation and to improve user interaction.
    • They can handle requests such as processing credit cards.

    Server-Side Scripting

    • Server-side languages execute on the server, not in the browser.
    • Server-side languages run on the server, and respond to client requests.
    • Server-side code is often used for databases, and the server may store information needed by the client-side.
    • Examples: PHP, Python, Ruby, Perl, C#, and ASP.
    • The server generates the HTML response to be displayed in the browser.
    • Server-side scripts are significantly faster in response time compared to client-side.

    Internet Application Architecture

    • Internet applications have a layered architecture.
    • The structure facilitates the use of resources, and helps with performance.
    • The layers are Application, Networked Applications, Transport, and Network/Communication.
    • Network/Communication provides links between devices.
    • Transport manages the transmission of data.
    • Networked application/Support enables the request and management of data
    • Applications operate at the top layer.

    XAMPP

    • XAMPP is a web server distribution bundle.
    • It bundles Apache, MySQL, PHP, and optionally Perl software.
    • These software are deployed as a single platform.
    • XAMPP installation has a "document root" directory.
    • XAMPP has a browser URL alias.
    • XAMPP is available on several operating systems: Linux, Windows, macOS, and Solaris.

    Structured Query Language (SQL)

    • SQL is embedded into scripts to perform operations like inserting, updating, or deleting records.
    • SQL is also useful with combining tables.
    • SQL commands are used for data management processes.
    • SQL is used to query databases and manage data.

    Client Tier, Middle Tier, and Information Tier

    • These tiers refer to the organization of client-based systems.
    • In a typical application, the client tier is at the top layer, connected to the middle tier and then the information tier at the bottom.
    • The information tier stores data.
    • The middle tier acts as a controller and processes the requests.
    • The client tier, the user interface interacting with the end user.
