Department of Information Technology

​

  

Information Technology (IT) is one of the most important fields of study and research, and ​it covers various topics such as programming, web development, computer security, software, data science, and many others. Due to huge demands of IT innovations in Uzbekistan and the world, KWTI offers a package of web development courses including both FRONT-END and BACK-END. The following are the two courses offered by this department:

FRONT-END

​

Front-end web development involves with creating the the user interface and user experience of a website or web application. It includes the design and implementation of the visual elements such as layout, content organization, graphics, and animation that users interact with, as well as ensuring the functionality and responsiveness of the interface across different devices and browsers.

​

Key aspects of front-end development include:

​

1. HTML (Hypertext Markup Language): HTML is the standard markup language used to create the structure of web pages. It defines the elements and content of a webpage, such as headings, paragraphs, images, links, and more.

2. CSS (Cascading Style Sheets): CSS is used to style the visual presentation of HTML elements. It controls aspects like layout, colors, fonts, and spacing, allowing developers to create visually appealing and consistent designs.

3. JavaScript: JavaScript is a programming language that adds interactivity and dynamic behavior to web pages. It enables developers to create features such as animations, form validation, and interactive elements that respond to user input.

4. Responsive Design: Front-end developers must ensure that websites are accessible and usable across various devices and screen sizes, including desktops, laptops, tablets, and smartphones. Responsive design techniques, such as fluid layouts and media queries, are employed to achieve this.

5. Cross-Browser Compatibility: Front-end developers need to ensure that websites function correctly and appear consistently across different web browsers, such as Chrome, Firefox, Safari, and Edge. This often involves testing and debugging to address compatibility issues.

6. UI/UX Design: User Interface (UI) design focuses on the visual aspects of the interface, including layout, typography, color schemes, and visual hierarchy. User Experience (UX) design involves understanding user behavior and preferences to create intuitive and enjoyable interactions.

7. Front-End Frameworks and Libraries: Front-end developers often use frameworks and libraries like React.js, Angular, Vue.js, and Bootstrap to streamline development, enhance productivity, and maintain code consistency.

 

The Front-end web development encompasses the creation of the client-side components of a website or web application, with a focus on designing an engaging and user-friendly interface while ensuring functionality, compatibility, and responsiveness across various platforms and devices.

​

BACK-END

​

Back-end development involves with developing the server side of web applications and focusing on the functionality and logic that powers the application behind the scenes. It includes managing data, processing requests from clients, and generating dynamic content to be delivered to users.

​

Key aspects of back-end development include:

​

1. Server-Side Programming Languages: Back-end developers use languages like Python, Ruby, Java, PHP, and Node.js to write the code that runs on the server. These languages handle tasks such as data processing, business logic implementation, and communication with databases.

2. Database Management: Back-end developers work with databases to store, retrieve, and manipulate data. They use database management systems like MySQL, PostgreSQL, MongoDB, and SQLite to organize and manage data efficiently.

3. APIs (Application Programming Interfaces): Back-end developers create APIs to enable communication between the front end and back end of web applications. APIs define the methods and protocols for accessing and interacting with the application's data and functionality.

4. Authentication and Authorization: Back-end developers implement authentication mechanisms to verify the identity of users and authorize access to protected resources. This often involves techniques like username/password authentication, OAuth, JWT (JSON Web Tokens), and session management.

5. Security: Back-end developers are responsible for implementing security measures to protect the application from various threats, such as SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), and data breaches. They employ techniques like encryption, input validation, and secure coding practices to mitigate risks.

6. Performance Optimization: Back-end developers optimize the performance of web applications by fine-tuning database queries, optimizing code execution, and implementing caching mechanisms. They aim to reduce latency, improve scalability, and enhance the overall user experience.

7. Scalability and Load Balancing: Back-end developers design and implement scalable architectures that can handle increasing amounts of traffic and users. They use techniques like load balancing, horizontal scaling, and microservices to distribute workloads efficiently across multiple servers or instances.

8. Infrastructure Management: Back-end developers may be involved in managing the infrastructure on which the application runs, including servers, databases, and cloud services. They ensure that the infrastructure is reliable, secure, and scalable to meet the demands of the application.

 

The back-end web development involves building and maintaining the server-side components of web applications, including managing data, processing requests, implementing security measures, optimizing performance, and ensuring scalability and reliability. It complements front-end development to create fully functional and dynamic web applications.
