Study Notes
Web Systems and Technologies
- Web Systems and Technologies encompass tools, frameworks, protocols, and methodologies for creating and managing web applications.
- Involves front-end interfaces and back-end systems necessary for web application functionality.
Front-End Development
- Technologies include HTML, CSS, JavaScript, and frameworks like React, Angular, and Vue.js.
- Focused on user interface (UI) and user experience (UX) to make web pages responsive, accessible, and interactive.
Back-End Development
- Utilizes server-side languages like Python (Django, Flask), PHP (Laravel), Ruby (Rails), Java (Spring), and Node.js (Express).
- Responsible for business logic, database interactions, APIs, authentication, and data processing.
Databases
- Types include SQL databases (MySQL, PostgreSQL) and NoSQL databases (MongoDB, Redis).
- Essential for storing and managing data essential for web applications.
Web Servers
- Examples include Apache, Nginx, and IIS.
- Serve web pages by processing requests and delivering content to users.
Web Protocols
- Key protocols include HTTP/HTTPS, FTP, REST, SOAP, and WebSockets.
- Govern how data is transmitted between clients (browsers) and servers.
Content Management Systems (CMS)
- Popular systems include WordPress, Joomla, and Drupal.
- Allow users to create and manage digital content without extensive technical know-how.
Web Hosting and Cloud Services
- Major providers are AWS, Google Cloud, and Microsoft Azure.
- Offer hosting for websites and scalable resources to manage varying traffic demands.
Security
- Implements technologies like SSL/TLS, OAuth, encryption, and firewalls.
- Protects web applications against threats like hacking and data breaches.
DevOps and CI/CD
- Tools include Jenkins, Docker, Kubernetes, and Git.
- Streamline development and deployment processes to enhance efficiency and reduce errors.
Web Analytics and SEO
- Tools such as Google Analytics, SEMrush, and Moz are used.
- Monitor web traffic, analyze user behavior, and optimize content for improved search engine visibility.
Web Applications
- Web applications operate on a web server and are accessed via a web browser.
- Examples include e-commerce platforms, social media, content management systems, streaming services, online learning platforms, and banking applications.
Current Trends and Technologies in Web
- Progressive Web Apps (PWAs): Hybrid of web and mobile apps.
- Single Page Applications (SPAs): Provide seamless experiences using frameworks like Angular and React.
- Serverless Architecture: Services such as AWS Lambda and Azure Functions facilitate backend management.
- WebAssembly (Wasm): Enables high-performance applications on the web.
- AI and Machine Learning: Integration enhances personalization and user experience.
- Voice Search Optimization: Adapts websites for voice-command queries.
- Cybersecurity: Increasing focus on safeguarding web applications from threats.
PHP Basics
- PHP (Hypertext Preprocessor): Open-source, server-side scripting language ideal for web development, created by Rasmus Lerdorf in 1994.
- Key features include server-side scripting, HTML embedding, cross-platform compatibility, database integration, extensive library support, and open-source nature.
How PHP Works
- User sends a request via their web browser to load a PHP page.
- The web server receives the request, identifies the PHP script, and executes the code to generate dynamic content.
