Study Notes
Internet Essentials
- Two requirements to connect to the web: Internet and Browser.
- The Internet is a global system of interconnected networks using standardized protocols.
- It is decentralized, enabling diverse and extensive communication between devices worldwide.
Major Components of the Internet
- Web Server: Uses HTTP to respond to client requests and requires an internet connection.
- Web Browser: Software that retrieves content from web servers to display on user screens.
Types of Internet Service
- Dial-up: Connects via modem to ISP.
- Broadband: High-speed internet faster than dial-up, delivered through cable or telephone lines.
- DSL: Broadband via telephone lines.
- Cable: High-speed internet through a cable modem.
- Satellite: Internet access through orbiting satellites.
Internet Programming Languages
- Server-Side: Validation and processing occur on the server. Examples include XML, Java, ASP.Net, and PHP.
- Client-Side: Programs run on the user's device, such as JavaScript and VBScript.
Evolution of the Web
- Web 1.0: Limited user interaction, primarily for reading information.
-
Web 2.0: Enhanced user engagement and dynamic content, featuring:
- Folksonomy: User-generated tagging for information organization.
- Rich User Experience: Content responds to user input.
- User Participation: Users can create content through comments and reviews.
- Long Tail Services: On-demand services rather than one-time purchases.
- Software as a Service: Renting software instead of installation.
- Mass Participation: Broad information sharing across platforms.
Web 3.0
- A W3C-led initiative allowing individualized user experiences and data sharing across applications.
- Limitations: Compatibility issues with existing HTML, security concerns with user data, and challenges in machine understanding.
Types of Web
- Website: Informational and mostly static collection of pages.
- Web App: Interactive collection of pages for user functionality and engagement.
Core Languages for Web Page Creation
- HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JavaScript.
HTML Overview
- Structure web pages using markup through tags.
- DOCTYPE: Declaration defines the HTML version.
- Elements: Metadata, audio controls, and/forms for user data collection.
HTML Tags and Forms
- Essential tags include
<html>,<head>,<title>, and<body>. - HTML forms collect data from users for further processing.
- Form Controls: Include text input, buttons, checkboxes, and radio box controls.
Text Input Controls
- Single-line: For short inputs (search boxes).
- Password: Masks user input for security.
- Multi-line: For longer responses needing detailed input.
Input Attributes
- type: Specifies the control type (text, password).
- name: Identifies control for server processing.
- value: Sets a default input value.
- size: Defines width in terms of characters.
