    Study Notes

    Basic Components of the Web

    • Web Servers: Computers that store and distribute content over the Internet, using HTML to format data.
    • Types of Servers: Can be PCs, Macintoshes, or UNIX workstations, differentiated by server software. Must remain operational for public access.
    • Web Clients: Devices like PCs and smartphones that access information from web servers, utilizing various client software such as Mosaic.
    • HTTP Protocol: Facilitates data transmission between clients and servers. It processes requests like file retrieval and delivers results swiftly.
    • Counterparts of HTTP: Includes protocols like FTP (File Transfer Protocol) for different types of data transfer.

    HTML5 Semantic Tags

    • Purpose of Semantic Elements: Enhance web page structure and meaning, making it easier for browsers and developers to navigate and manage layouts.
    • Key Elements: Include header, footer, section, nav, aside, and dialog, which provide meaningful content organization compared to traditional DIV tags.
    • Examples of Structural Elements: The introduction of semantic tags allows for clearer layout definitions, improving overall web design and comprehension.

    HTTP Protocol

    • Definition: An application protocol for communication over the Web, allowing data exchange between clients and servers.
    • Purpose: To enable interaction with web resources, facilitating user requests for documents that are returned in a usable format.
    • Request-Response Mechanism: Users send requests via web browsers that are processed by servers, with responses transmitted back in various formats such as HTML and images.

    HTML Overview

    • Language of the Web: HTML (Hypertext Markup Language) is essential for creating functional web pages, first developed by Tim Berners-Lee and others in 1989.
    • Latest Version: HTML5, which incorporates new elements for enhanced structure and semantics in web design.
    • File Extensions: HTML files typically end with .html or .htm.

    HTML Editors

    • Types of Editors: Simple text editors (like Notepad) can be used to create HTML, but specialized editors improve ease of use through features like syntax highlighting.
    • Recommended Free Editors: Notepad++, Visual Studio Code, and Sublime Text.

    HTML Tags

    • Structure: Tags are enclosed in angle brackets and usually occur in pairs (opening and closing tags) to define content types.

    Image Formats

    • JPG: Ideal for photo storage due to small file sizes without losing color quality; suited for images with gradients.
    • GIF: Best for simple animations; limited color palette and not suitable for photographs.
    • PNG: Good for non-photographic images; larger file size than JPG but supports transparency.
    • SVG: Vector-based format that scales without losing quality, great for responsive design.

    Image Best Practices

    • Alt Attributes: Essential for accessibility and improving SEO; they provide text alternatives for images.
    • Image Alignment: Control horizontal alignment using tags before and after image tags, and vertical alignment with specific attributes.
