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

A website is a collection of linked web pages accessible via the internet, likened to a digital book with chapters.
Websites serve diverse purposes including information retrieval, video watching, and online shopping.

Website Functionality

Websites function by exchanging information with servers over the internet.
User input, such as typing a URL, triggers a request to the server, which responds by delivering the requested page almost instantly.
