Web Systems Overview
- Web systems combine tools and platforms for creating, deploying, and managing websites and applications.
- Key components include Front-end, Back-end, Database, and Hosting.
Front-End
- Front-end is the visual part users interact with, encompassing design and content.
- Key technologies:
- HTML structures the webpage with elements like headings and links.
- CSS styles the webpage, controlling colors, fonts, and layouts.
- JavaScript adds interactivity, enabling features like form validation and dynamic updates.
Back-End
- Back-end operates behind the scenes, managing server-side logic and data processes.
- Handles tasks such as user authentication during logins by checking credentials.
- Ensures website functionality and smooth operation for users.
Database
- Databases store critical data for web applications, including user accounts and transactions.
Hosting
- Hosting provides the server infrastructure needed for websites to be accessible on the internet.
Evolution of the Web
- WEB 1.0: Characterized by static HTML pages, limited interaction (e.g., GeoCities).
- WEB 2.0: Introduced user-generated content and dynamic interactivity (e.g., Facebook, Twitter).
- WEB 3.0: Focuses on decentralization and AI, utilizing blockchain technology (e.g., DApps).
Websites Defined
