Internet Applications Programming - Chapter 1

  • Internet: A vast network of interconnected computers enabling global information sharing and communication.

  • World Wide Web (WWW): A system of interconnected hypertext documents accessible via the internet. Formatted in HTML and accessed using HTTP.

  • World Wide Web Consortium (W3C): An international organization standardizing the web to ensure interoperability and cooperation among web developers. Established in 1994 by Tim Berners-Lee.

  • Website: A collection of related web pages, identified by a common domain name, hosted on one or more servers. Examples include personal, corporate, government, and organizational sites.

  • Web Page: A document suitable for viewing on web browsers and the WWW. Typically written in HTML and displayed on monitors or mobile devices.

  • Web Browser: Software applications used to access web pages. Popular browsers include Chrome, Firefox, Safari, and Internet Explorer.

  • Web Server: A computer program that stores, processes, and delivers web pages to clients. Communication uses HTTP protocol. Delivered pages are often HTML documents, potentially including images, style sheets, and scripts alongside text.

  • Web Page Addresses (URL): Uniform Resource Locators specify the location of a resource (example: a web page) on the internet, defining the protocol, domain name, and path to the requested resource.

  • URL Components: URLs have protocols (e.g., http, https), domain names (e.g., www.example.com), and paths (e.g., /index.html) to locate specific web pages.

  • Domain Names: Human-readable names for locations on the internet where resources are stored, often websites. For example, microsoft.com is a domain name.

  • Paths: Parts of URLs indicating the specific files or resources within a server.

  • Domain Registrar: Companies providing domain registration services and managing the database of registered domain names, including propagating information across the internet.

  • Web Client: A software application (like a web browser) that requests and receives web pages from a web server.

  • HTTP: Hypertext Transfer Protocol; the standard protocol for communication between web browsers and web servers.

  • HTTP Request: When a web client wants a web page, it issues an HTTP request.

  • HTTP Response: The web server returns an HTTP response with the requested data.

  • Primary Web Technologies:

    • HTML: Hypertext Markup Language for creating web pages' structure and content.
    • CSS: Cascading Style Sheets for controlling the appearance of web pages.
    • JavaScript (JS): Used for interactive components within web pages.
    • PHP: Server-side scripting language for dynamic web pages and interactions.
    • Structured Query Language (SQL): For managing and interacting with databases, often when dealing with large amounts of information.
