FIRST TOPIC

• Web systems refer to the architecture, components, and technologies that power the World Wide Web.

  
  

  Web systems enable the creation, delivery, and interaction with web-based applications and content
• Web Browser: The client-side component that users use to interact with the web system
• User Interface (UI): The visual elements and design that users interact with on the web page
• Client-Side Scripting: Code executed on the user's browser (e.g., JavaScript) to enhance interactivity
• Web Server: The server responsible for receiving and responding to requests from clients. Examples include Apache, Nginx, or Microsoft IIS
• Application Server: Executes server-side code and processes business logic. Examples include Node.js, Django, Ruby on Rails, or Java EE
• Database Server: Manages and stores data. Common databases include MySQL, PostgreSQL, MongoDB, or Microsoft SQL Server
• HTTP/HTTPS: The protocol used for communication between the client and the server. HTTPS provides a secure version of HTTP, often used for sensitive transactions
• Monitoring Tools: Keep track of the web system's performance, availability, and errors
• Logging Systems: Record events and activities for debugging and analysis
• Authentication Services: Verify the identity of users
• Authorization Services: Control access to specific resources or functionalities based on user permissions
• HTML/CSS: Structure and styling
• JavaScript: Dynamic and interactive features
• Front-End Frameworks: React, Angular, Vue.js
• Programming Languages: Python, Node.js, Ruby, Java
• Server-Side Frameworks: Flask, Express, Django, Ruby on Rails
• APIs (Application Programming Interfaces): Enable communication between front-end and back-end
• Progressive Web Apps (PWAs): Combining web and mobile app features
• Serverless Architecture: Executing code without managing servers
• Machine Learning in Web Development: Enhancing user experience
• WebAssembly (Wasm): High-performance binary format for the web
• Key Components of a Web System
