What is Angular JS?

AngularJS is a JavaScript-based open-source front-end web framework mainly maintained by Google and by a community of individuals and corporations to address many of the challenges encountered in developing single-page applications. It aims to simplify both the development and the testing of such applications by providing a framework for client-side model–view–controller (MVC) and model–view–ViewModel (MVVM) architectures, along with components commonly used in rich Internet applications. (This flexibility has led to the acronym MVW, which stands for "model-view-whatever" and may also encompass model–view–presenter and model–view–adapter.) In 2014, the original AngularJS team began working on the Angular web framework.

The AngularJS framework works by first reading the Hypertext Markup Language (HTML) page, which has additional custom HTML attributes embedded into it.

Angular interprets those attributes as directives to bind input or output parts of the page to a model that is represented by standard JavaScript variables.

The values of those JavaScript variables can be manually set within the code, or retrieved from static or dynamic JSON resources.

Artificial Intelligence in brief !

The Artificial Intelligence tutorial provides an introduction to AI which will help you to understand the concepts behind Artificial Intelligence. In this tutorial, we have also discussed various popular topics such as the History of AI, applications of AI, deep learning, machine learning, natural language processing, Reinforcement learning, Q-learning, Intelligent agents, Various search algorithms, etc.

In computer science, artificial intelligence (AI), sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and animals. Colloquially, the term "artificial intelligence" is used to describe machines that mimic "cognitive" functions that humans associate with other human minds, such as "learning" and "problem-solving".

Why Artificial Intelligence?

  • With the help of AI, you can create software or devices which can solve real-world problems very easily and with accuracy such as health issues, marketing, traffic issues, etc.
  • With the help of AI, you can create your personal virtual Assistant, such as Cortana, Google Assistant, Siri, etc.
  • With the help of AI, you can build Robots that can work in an environment where the survival of humans can be at risk.
  • AI opens a path for other new technologies, new devices, and new opportunities.

Artificial intelligence can be classified into three different types of systems: analytical, human-inspired, and humanized artificial intelligence. Analytical AI has only characteristics consistent with cognitive intelligence; generating a cognitive representation of the world and using learning based on past experience to inform future decisions. Human-inspired AI has elements from cognitive and emotional intelligence; understanding human emotions, in addition to cognitive elements, and considering them in their decision making. Humanized AI shows characteristics of all types of competencies (i.e., cognitive, emotional, and social intelligence), is able to be self-conscious, and is self-aware in interactions with others.

Goals of Artificial Intelligence

  • Replicate human intelligence
  • Solve Knowledge-intensive tasks
  • An intelligent connection of perception and action
  • Creating some system that can exhibit intelligent behavior, learn new things by itself, demonstrate, explain, and can advise its user.


Introduction to Asp.net Core

ASP.NET Core is the new version of the ASP.NET Web Framework mainly targeted to run on the .NET Core Platform.

ASP.NET Core is a free and open-source web framework, and higher performance than ASP.NET, developed by Microsoft and the community. It is a modular framework that runs on both the full .NET Framework, on Windows, and the cross-platform .NET Core. However, the expected version ASP.NET Core 3 was announced to work only on .NET Core dropping support of .NET Framework.

The framework is a complete rewrite that unites the previously separate ASP.NET MVC and ASP.NET Web API into a single programming model.

ASP.NET Core features

  • Cross-platform, open-source now runs your app over Linux, Windows, Mac;   i.e., wherever you want.
  • Fast Development- fast work over the Browsers.
  • Work in your editors - now you can work not only in Visual Studio. You can also choose Visual Studio code and if you
  • want to work on your command on the command prompt, then you can.

Despite being a new framework, built on a new web stack, it does have a high degree of concept compatibility with ASP.NET MVC. ASP.NET Core applications support side-by-side versioning in which different applications, running on the same machine, can target different versions of ASP.NET Core. This is not possible with previous versions of ASP.NET.

Introduction to JQuery

jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript.

jQuery's syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications. jQuery also provides capabilities for developers to create plug-ins on top of the JavaScript library. This enables developers to create abstractions for low-level interaction and animation, advanced effects, and high-level, themeable widgets. The modular approach to the jQuery library allows the creation of powerful dynamic web pages and Web applications.

jQuery Features

  • HTML manipulation
  • DOM manipulation
  • DOM element selection
  • CSS manipulation
  • Effects and Animations
  • Utilities
  • AJAX
  • HTML
  • event
  • methods
  • JSON
  • Parsing
  • Extensibility
  • through
  • plug-ins

Why jQuery is required

  • It is very fast and extensible.
  • It facilitates the users to write UI-related function codes in minimum possible lines.
  • It improves the performance of an application.
  • Browser's compatible web applications can be developed.
  • It uses mostly new features of new browsers.

There are lots of other JavaScript libraries out there, but jQuery is probably the most popular, and also the most extendable.

What is MVC?

MVC stands for Model, View, and Controller. MVC separates an application into three components - Model, View, and Controller.

MVC Architecture

Model: Model represents the shape of the data and business logic. It maintains the data of the application. Model objects retrieve and store model state in a database.

View: View is a user interface. View display data using a model to the user and also enables them to modify the data.

Controller: The controller handles the user request. Typically, a user interacts with View, which in-turn raises an appropriate URL request, this request will be handled by a controller. The controller renders the appropriate view with the model data as a response.

As per the above figure, when the user enters a URL in the browser, it goes to the server and calls an appropriate controller. Then, the Controller uses the appropriate View and Model and creates the response and sends it back to the user.

What is CSS? Advantages of using CSS.

Cascading Style Sheets, fondly referred to as CSS, is a simple design language intended to simplify the process of making web pages presentable.

CSS handles the look and feel part of a web page. Using CSS, you can control the color of the text, the style of fonts, the spacing between paragraphs, how columns are sized and laid out, what background images or colors are used, layout designs, variations in display for different devices, and screen sizes as well as a variety of other effects.

Advantages of CSS:

CSS saves time − You can write CSS once and then reuse the same sheet in multiple HTML pages. You can define a style for each HTML element and apply it to as many Web pages as you want.

Pages load faster − If you are using CSS, you do not need to write HTML tag attributes every time. Just write one CSS rule of a tag and apply it to all the occurrences of that tag. So less code means faster download times.

Easy maintenance − To make a global change, simply change the style, and all elements in all the web pages will be updated automatically.

Superior styles to HTML − CSS has a much wider array of attributes than HTML, so you can give a far better look to your HTML page in comparison to HTML attributes.

Multiple Device Compatibility − Style sheets allow content to be optimized for more than one type of device. By using the same HTML document, different versions of a website can be presented for handheld devices such as PDAs and cell phones or for printing.

Global web standards − Now HTML attributes are being deprecated and it is being recommended to use CSS. So it's a good idea to start using CSS in all the HTML pages to make them compatible with future browsers.


One of the primary advantages of CSS is that it allows developers to separate content from its presentation layer. CSS changes the traditional method of setting style and layout on each individual web page by allows CSS designers to use a single file to control the style and layout of multiple web pages on the same website.

It is the job of CSS to define the styles of the HTML document. So with CSS, you have much better control over the layout of your web pages. You can specify exactly how big the font will be, exactly where an element will be on a page, what the page will look like when printed, and much more.

CSS is easy to learn and understand but it provides powerful control over the presentation of an HTML document. Most commonly, CSS is combined with the markup languages HTML or XHTML.

The main goal (as a method sheet language) was to separate document content from document presentation, which incorporates style elements, like color, layout, and fonts. CSS handles the design and feels a part of an internet page. Using CSS, you will control the color of the text, the design of fonts, the spacing between paragraphs, how columns are sized and laid out, etc.

Blazor | Free and Open-Source Web Framework

Blazor is a Single Page Application development framework. The name Blazor is a combination/mutation of the words Browser and Razor (the .NET HTML view generating engine). The implication is that instead of having to execute Razor views on the server in order to present HTML to the browser, Blazor is capable of executing these views on the client.

Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code is written in C#, allowing you to share code and libraries. Blazor is a feature of ASP.NET, the popular web development framework that extends the .NET developer platform with tools and libraries for building web apps.

Blazor uses open web standards without plugins or code transpilation. Blazor works in all modern web browsers, including mobile browsers.

Code running in the browser executes in the same security sandbox as JavaScript frameworks. Blazor code executing on the server has the flexibility to do anything you would normally do on the server, such as connecting directly to a database.

Bootstrap

Bootstrap is the most popular CSS framework for developing responsive and mobile-first websites.

Bootstrap is a giant collection of handy, reusable bits of code written in HTML, CSS, and JavaScript. It’s also a front-end development framework that enables developers & designers to quickly build fully responsive websites.

Bootstrap saves you from writing lots of CSS code, giving you more time to spend on designing webpages.

Why Use Bootstrap?

Advantages of Bootstrap:

  • Easy to use: Anybody with just basic knowledge of HTML and CSS can start using Bootstrap
  • Responsive features: Bootstrap's responsive CSS adjusts to phones, tablets, and desktops
  • Mobile-first approach: In Bootstrap 3, mobile-first styles are part of the core framework
  • Browser compatibility: Bootstrap is compatible with all modern browsers (Chrome, Firefox, Internet Explorer, Edge, Safari, and Opera)

Bootstrap contains a variety of design templates. These design templates are based on and work with the following:

  • HTML
  • CSSLess (version 3)
  • Sass (version 4)
  • JavaScript
  • Extensions (Optional)

Appealing Features of Bootstrap

Bootstrap has a lot of features. These features not only make it stand out, but they also make it more popular even among those web designers who like to take things in a very conventional way.

1. Easy to Begin With
It is pretty easy, to begin with. Being easy to get started with is probably the first quality that makes Bootstrap very appealing.

2. LESS as Well as CSS Files
Bootstrap not only offers LESS files but also includes the old CSS files.

3. Easily Customizable
Despite the fact that Bootstrap is designed in responsive 12-column grids, layouts, and components, it is also very easy to customize. Whether you need a fixed grid or a responsive one, it can be made possible by making a few changes. Offsetting and nesting of columns are also easy to do in both CPU-based and mobile-based browser grids.

4. Responsive Utility Classes
Another prominent feature of Bootstrap is its responsive utility classes. Using responsive utility classes, a particular piece of content can be made to appear or hide only on devices depending on the size of the screen being used. This feature is extremely helpful for designers who want to make a mobile and tablet-friendly version of their websites.

5. Components of Bootstrap
Some of the components that come pre-styled in Bootstrap are:

  1.Drop-downs

  2.Button

  3.Navigation

  4.Badges Alerts

  5.Progress Bar

6. Drop-Down Component Menu
The drop-down component menu is a responsive additive feature of a website. To include it in a website, a lot of different plugins, mostly Java-based, are tested. But, via Bootstrap and its easy customizing options, this can easily be done in a matter of minutes.

7. Bootstrap Templates
The readily available templates make it easier for inexperienced users to create a website following a simple tutorial or demo available on Bootstrap.





About XML

XML stands for Extensible Markup Language. It is a text-based markup language derived from Standard Generalized Markup Language (SGML).

XML tags identify the data and are used to store and organize the data, rather than specifying how to display it like HTML tags, which are used to display the data. XML is not going to replace HTML in the near future, but it introduces new possibilities by adopting many successful features of HTML.

There are three important characteristics of XML that make it useful in a variety of systems and solutions −

  • XML is extensible − XML allows you to create your own self-descriptive tags, or language, that suits your application.
  • XML carries the data, does not present it − XML allows you to store the data irrespective of how it will be presented.
  • XML is a public standard − XML was developed by an organization called the World Wide Web Consortium (W3C) and is available as an open standard.

XML Usage:

A shortlist of XML usage says it all −

   1.XML can work behind the scene to simplify the creation of HTML documents for large websites. 

   2.XML can be used to exchange information between organizations and systems.     

   3. XML can be used to store and arrange the data, which can customize your data handling needs. 

   4.XML can easily be merged with style sheets to create almost any desired output.   

   5.XML can be used for offloading and reloading databases.         

   6.Virtually, any type of data can be expressed as an XML document.

Platform Independent and Language-Independent: The main benefit of XML is that you can use it to take data from a program like Microsoft SQL, convert it into XML then share that XML with other programs and platforms. You can communicate between two platforms which is generally very difficult.

The main thing which makes XML truly powerful is its international acceptance. Many corporations use XML interfaces for databases, programming, office application mobile phones, and more. It is due to its platform-independent feature.
