• Web servers respond to client requests by either serving files associated with requested URLs or generating responses via scripts interacting with databases.
• If a requested page is found, the server sends it back with an HTTP response; otherwise, it returns a 404 Not Found error.

Internet Service Provider (ISP)

• ISPs offer internet access using various technologies such as dial-up, DSL, and cable modems.
• Many ISPs provide email accounts for users, facilitating email communication through their servers.

Apache HTTP Server

• Installation of Apache is often bundled with Linux distributions; configuration is similar across different Unix variants.

Internet Information Services (IIS)

• IIS is a web server created by Microsoft, used for hosting web pages on Windows computers.
• IIS must be manually installed and is not pre-installed on most Windows operating systems.

Publishing Websites on IIS

• To publish a website, create a home page named Default.htm or Default.asp and place it in the default web directory, typically located at \Inetpub\wwwroot.
• FTP publishing requires files to be moved to the \Inetpub\Ftproot directory; visitors can access via computer name or IP.

Domain Names

• A domain name uniquely identifies a website, such as microsoft.com, and must be registered in a DNS system.

Learning Outcomes

• Understanding how to create SPAs using AngularJS and manage UI interactions through its components is critical for modern web development.

AngularJS Overview

• AngularJS is a JavaScript framework for building dynamic web applications.
• It utilizes modules that contain components including directives, services, filters, and templates.
• Documentation includes external resources and guides on various AngularJS topics.

AngularJS APIs

• Organized into modules featuring directives, services, filters, providers, templates, and global APIs.
• Offers testing mocks for enhancing application testing processes.
• APIs can be accessed for further learning and implementation.

AngularJS Animations

• Supports animated transitions using CSS for directives like ngRepeat, ngSwitch, and ngView.
• The $animate service facilitates custom directives with animation capabilities.
• Animations can be triggered during the lifecycle of directives, promoting a responsive user experience.

AJAX in AngularJS

• AJAX allows for retrieving information from a database and sending user details to a server without reloading the page.
• Utilizes XMLHttpRequest object for direct server communication, enhancing application performance.
• Reduces the number of full page reloads, improving user-friendliness.

Event Driven Programming

• Based on interactions where events control program flow.
• Utilizes event listeners and handlers to improve responsiveness.
• Suitable for setting up event-driven architectures alongside RESTful APIs, ensuring data integrity.

Data Binding

• Two-way data binding automatically synchronizes the model and view.
• Changes in the model update the view, and vice versa, ensuring real-time data reflection.
• Simplifies user interactions in web applications, enhancing usability.

Single Page Applications (SPAs)

• SPAs dynamically rewrite requested pages rather than completely loading new ones, allowing for a smoother user experience.
• Code (HTML, JavaScript, CSS) is retrieved in a single page load, reducing necessary page refreshes.
• Heavily relies on AJAX for communication with back-end servers, significantly improving load times and responsiveness.

Directive Usage in AngularJS

• Directives can be invoked using Element name, Attribute, Class, or Comment.
• Each directive can have a restrict property that limits how it can be called.
• Default directive restriction allows both Element names and attributes; customization is possible to refine invocation methods.

AngularJS Directives

• A directive is defined in AngularJS to create reusable components.
• Directives can be invoked by Element names, Attributes, Classes, or Comments.
• Legal restrictions for directive invocation:
  • E: Element name
  • A: Attribute
  • C: Class
  • M: Comment
• Default restriction is EA, allowing invocation through both Element names and attributes.
• Setting the restrict property to "A" limits invocation to attributes only.

Event-Driven Programming in AngularJS

• Event-driven programming mimics human interactions, controlling application flow based on event occurrences.
• Events are monitored by event listeners that trigger event handlers or callback functions.
• Enhances program responsiveness and flexibility, ideal for applications using RESTful APIs.
• AngularJS promotes two-way data binding and data integrity in real-time.

jQuery Selectors and Event Handling

• jQuery selectors allow targeting specific elements:
  • $(":animated"): Selects currently animated elements.
  • $("[href]"): Selects elements with a href attribute.
  • $(":button"): Targets button elements.
  • $(":even"): Selects even-indexed elements.
  • $(":odd"): Selects odd-indexed elements.
• Event handling example:
  • Clicking the "Hide" button will hide a paragraph.
  • Clicking the "Show" button will display the paragraph.

jQuery Form Validation

• jQuery is commonly used for form data validation.
• Validations help identify incomplete input data before server submission.
• A form can be validated using specific rules set in jQuery.

JavaScript Programming Concepts

• JavaScript is structured to handle various programming elements:
  • Conditional Statements: Perform different actions based on decisions.
    • Examples include IF…ELSE, Nested Structures, and Ternary Operators.
  • Selection Statements: Handle multiple options using Switch structures.
  • Functions can take parameters, enabling dynamic behavior.
  • Iterative functions are used for repeating actions.

Learning Outcomes

• At the end of the lesson, students will learn:
  • Writing programs using conditional statements.
  • Utilizing selection statements for multiple options.
  • Creating functions and passing parameters effectively.
  • Basic data input and handling within JavaScript.
  • Understanding data type conversions associated with JavaScript programming.

JavaScript Strings

• Strings can be defined using single or double quotes.
• Quotes within strings must differ from the surrounding quotes, e.g., "It's alright" or 'He is called "Gamini"'.

JavaScript Numbers

• Only one type of number exists in JavaScript, which can be integer or decimal.
• Use scientific notation for very large or small numbers, e.g., 123e5 (12,300,000) and 123e-5 (0.00123).

JavaScript Booleans

• Booleans represent two values: true or false.
• Example comparison: (x == y) is true if x and y are equal, otherwise false.

JavaScript Events and Functions

• JavaScript can execute on user interaction, such as clicking HTML elements.
• Assign JavaScript to HTML events like onclick to trigger functionalities upon user actions.

setInterval() Method

• setInterval() repeats a specified function at defined time intervals.
• Example implementation to display time every second using myTimer function and setInterval().

clearTimeout() Function

• Used to stop the execution of a function initiated by setInterval().
• Relies on the variable returned by setInterval() to clear the function call.

jQuery Validation

• Forms can be validated using rules defined for each input field, ensuring criteria like required fields and correct email format.
• Customize validation error messages for improved user feedback during form submission.

Web Hosting and Maintenance

• The lesson extends knowledge about hosting websites and maintaining them remotely through various platforms.
• Linux servers are known for stability and a wide feature set, providing a foundation for web hosting.

Web Servers

• Web servers respond to client requests by delivering resources, like HTML pages.
• Two main types discussed are Apache HTTP Server and Microsoft IIS, both suitable for testing web applications locally.

Internet Service Provider (ISP)

• An ISP provides customers with internet access, facilitating browsing and web interactions.

AngularJS Directives

• AngularJS allows directives to be invoked via elements, attributes, classes, or comments.
• Directives can be restricted to specific invocation methods by setting the restrict property.

Event-Driven Programming in AngularJS

• This programming model reacts to events controlled by user interactions.
• Event listeners monitor events and execute designated handlers, enhancing application flexibility.
• Suitable for interfacing with RESTful APIs, facilitating data integrity and synchronization.

This quiz covers the fundamentals of Dynamic HTML and its applications in web development. Students will learn how to implement dynamic behavior on web interfaces and write basic scripts using JavaScript. By the end, learners will grasp essential script-programming concepts.
