  What is Web Development? Definitionand Scope Web development refers to the process of creating, building, and maintaining websites. It involves coding, designing, and managing the infrastructure needed for a website to function effectively.

  The Role ofHTML, CSS, and JavaScript The combination of HTML, CSS, and JavaScript enables developers to create comprehensive web applications that are not only structured and styled but also interactive, enhancing user engagement and overall experience. HTML (Hypertext Mark-up Language): Defines the structure of a web page using elements like headings, paragraphs, links, and images. Which act as building blocks for creating the content and layout of a web page using a set of codes. CSS (Cascading Style Sheet): Used to style the appearance the web page, controlling and standardizing layout, colours, fonts, and other visual aspects of the content. JavaScript: Adds interactivity, it enables developers to create dynamic and interactive elements such as form validation, animations, and dynamic content updates.

  WEB APPLICATION LANGUAGES PopularProgramming Languages: • Java • C# • Perl • VB • PHP • Python • Ruby • Golang
• 8.
  CMS: Tools likeWordPress or Joomla that simplify content management without requiring coding. Frontend: Involves user-facing elements (HTML, CSS, JavaScript). • SPA (React, Angular, Vue.js) Backend: Manages server-side logic, databases, and APIs. (Node.js, PhP, Ruby, Phyton, Golang) Full-Stack: Combines both frontend and backend skills. • Frameworks (Laravel, Yii2, Django, ASP.Net) CMS, FRONTEND, BACKEND, AND FULL-STACK

  Databases store andorganize data used in web applications. Relational Databases: • MySQL • PostgreSQL • SQLite • MariaDB • SQL Server • Oracle NoSQL • MongoDB • Redis • Cassandra DATABASE

  Software like Apache,Nginx, Tomcat, IIS, Node.js or cloud services (AWS, Azure) that host websites and deliver web content to users' browsers. WEB SERVER • Serving Content: Delivers static content (e.g., HTML, CSS, JavaScript files) and dynamic content generated by server- side languages like PHP or JSP. • Handling HTTP Requests: Receives and processes HTTP/HTTPS requests from clients (browsers) and sends the appropriate responses. • Dynamic Content Generation: Executes server-side scripts or applications (e.g., PHP, Python, JSP) to generate dynamic web pages based on user input or database queries. • Security: Implements HTTPS for secure communication, protecting data during transfer. • Load Balancing: Distributes incoming traffic across multiple servers to ensure scalability and reliability. • Middleware Integration: Acts as a bridge between the frontend (user-facing) and backend (databases, APIs) for data exchange. • Error Handling: Displays error pages (e.g., 404, 500) to inform users of issues like missing resources or server errors.
• 11.
  PROTOCOLS Define communication rulesbetween web browsers and servers. Key protocols: HTTP/HTTPS (data transfer), FTP (file transfer), DNS (domain resolution). • A Web page is identified by a unique address called the URL • Each URL consists of two basic parts: – A protocol (usually HTTP or HTTPS) – Either the domain name for a Web server or a Web server’s Internet Protocol address • Hypertext Transfer Protocol (HTTP) manages the hypertext links that are used to navigate the Web • Hypertext Transfer Protocol Secure (HTTPS) provides secure Internet connections for transactions that require security and privacy https://www.google.com/help/index.html | | | | Protocol Domain name Directory Filename

  WEB SECURITY Protects websitesand user data from threats like hacking and malware. Key measures: SSL (Secure Sockets Layer)/TLS(Transport Layer Security) encryption, secure passwords, input validation, and regular updates. • SSL/TLS Encryption: Secures data transmission between the browser and server, ensuring confidentiality. • Secure Passwords: Enforces strong, unique passwords with multi- factor authentication (MFA). • Input Validation: Prevents attacks like SQL injection and cross-site scripting (XSS) by validating user inputs. • Regular Updates: Keeps software, plugins, and frameworks up-to-date to patch vulnerabilities.

  WEB DEVELOPMENT TOOLS CodeEditors: • Visual Studio Code • Sublime Text • Atom • eclipse • Jetbrains: (PHPStorm, WebStorm, PyCharm, RubyMine, Goland) Database Management: • PHPMyadmin • Dbeaver • SSMS • Navicat • MongoDB Compass • Oracle SQL Server • Toad for Oracle

  Planning: Define requirementsand goals. Designing: Create mockups and wireframes. Development: Write code and integrate features. Testing: Debugging and performance testing. Deployment: Launch the website. Maintenance: Ongoing updates and support. Web Development Process
