    Study Notes

    Client-Server Model

    • Servers handle incoming requests from clients but do not initiate services themselves.
    • A server program runs indefinitely unless interrupted by an issue.

    Advantages of Client-Server Networks

    • Centralized Data: All data is stored on the server.
    • Security: Resources are centrally managed for enhanced security.
    • Performance: Dedicated servers improve the speed of shared resources.
    • Scalability: Allows for separate scaling of clients and servers.

    Disadvantages of Client-Server Networks

    • Traffic Congestion: High request volumes can slow down server response.
    • Server Downtime: When servers fail, clients cannot access services.
    • Hardware Limitations: Regular hardware may not support multiple clients, requiring specialized server hardware.
    • Vulnerability to Attacks: Clients can get infected by malware; servers are susceptible to Denial of Service (DoS) attacks.
    • Data Transmission Risks: Packets can be spoofed or modified during transit.

    Types of Web Developers

    • Frontend Developers: Use HTML and CSS to design user interfaces that function across devices.
    • Backend Developers: Code the server-side logic and manage user input actions (e.g., processing form submissions).
    • Full Stack Developers: Capable of working on both frontend and backend, adapting based on project needs.

    Introduction to HTML

    • HTML: Stands for Hyper Text Markup Language; foundational language for structuring web pages.
    • Uses HTML tags for defining elements, which are enclosed in angle brackets (<>).
    • HTML files must have a .html or .htm extension and can be created with any text editor.

    Web Page Structure Considerations

    • Plan the type of content and information to include on the website.
    • Establish clear goals for the site and organize content into main topics and a logical structure.

    HTML Tags and Elements

    • HTML elements are indicated by tags that typically appear in pairs (start and end tags).
    • Tags are not case sensitive; both <TAG> and <tag> are valid.
    • The text between the start and end tags constitutes the element's content.

    Creating and Viewing HTML Documents

    • Write HTML in a text editor (e.g., Visual Studio, Notepad).
    • Save the document with a .html extension to create a document source.
    • View the HTML page using a web browser by navigating to the saved file.

    HTML Image Handling

    • Image Tag: Defined with <img> and requires the src attribute for the image's URL.
    • Images can be placed within content and will render where the tag appears in the document.
    • Images can be adjusted for size and alignments according to layout needs.

    HTML Tables

    • Tables are created using the <table> tag, with rows defined by <tr> and data cells by <td>.
    • The border attribute displays table borders, which are not shown by default.

    HTML Frames and Framesets

    • Frames allow the division of the web page into multiple sections using <frameset>.
    • Columns can be defined with specific sizes (in pixels or percentages) to manage spacing.

    HTML Forms

    • Forms collect user input and are indicated by the <form> tag.
    • Common input types include text fields, radio buttons, and checkboxes, each defined by their respective tags (e.g., <input>).

    Handling Form Submissions

    • The action attribute of a form determines where the form data is sent upon submission.
    • Forms can include diverse input fields and interactive elements like buttons for submission.

    Best Practices for Forms

    • Use clear labels and structures to guide user interaction.
    • Allow for multiple selections with checkboxes and single selections with radio buttons.
    • Ensure forms have a designated backend to process the data collected efficiently.
