Study Notes
Definition
- Web technology refers to the tools, programming languages, and protocols used to create and maintain websites and web applications.
Key Components
-
HTML (HyperText Markup Language)
- Standard markup language for creating web pages.
- Structures content using elements such as headings, paragraphs, links, and images.
-
CSS (Cascading Style Sheets)
- Style sheet language used for describing the presentation of a document written in HTML.
- Controls layout, colors, fonts, and overall visual appearance.
-
JavaScript
- A programming language that enables interactive web pages.
- Used for client-side scripting to enhance user experience (e.g., form validations, dynamic content).
-
Web Servers
- Software or hardware that serves web pages to users.
- Common servers include Apache, Nginx, and Microsoft IIS.
-
Databases
- Systems for storing and managing data used by web applications.
- Popular databases include MySQL, PostgreSQL, and MongoDB.
Protocols
-
HTTP/HTTPS (HyperText Transfer Protocol/Secure)
- Protocol for transferring hypertext requests and information on the internet.
- HTTPS provides a secure version using encryption (SSL/TLS).
-
FTP (File Transfer Protocol)
- Standard network protocol for transferring files between a client and a server.
Frameworks and Libraries
-
Frontend Frameworks
- React, Angular, Vue.js: Libraries/toolkits for building user interfaces and single-page applications.
-
Backend Frameworks
- Node.js, Django, Ruby on Rails: Libraries for building server-side applications.
Development Tools
-
Version Control Systems
- Git, GitHub: Tools for tracking changes in source code during software development.
-
Integrated Development Environments (IDEs)
- Visual Studio Code, Atom, Eclipse: Software applications that provide comprehensive facilities for software development.
Web Standards and Accessibility
- Guidelines and best practices established by W3C (World Wide Web Consortium) to ensure consistency, interoperability, and access to web content for all users, including those with disabilities.
Trends and Innovations
-
Responsive Design
- Approach to web design aimed at making web pages render well on various devices and screen sizes.
-
Progressive Web Apps (PWAs)
- Web applications that use modern web capabilities to deliver an app-like experience.
-
APIs (Application Programming Interfaces)
- Set of rules and protocols for building and interacting with software applications, facilitating integration between different services.
Security Considerations
- Importance of securing web applications against vulnerabilities (e.g., SQL injection, cross-site scripting).
- Utilization of HTTPS, content security policies, and regular security audits to protect web data.
